water pumping station for giving, which water pumping home station to choose, the choice of how to choose a household autonomous station

Every year more and more peo­ple start sum­mer cot­tages. Many come to their coun­try house for the week­end to relax. For oth­ers, a dacha is a place to live per­ma­nent­ly. It is for such peo­ple that it is extreme­ly impor­tant to cre­ate com­fort­able con­di­tions in their coun­try hacien­da.

For any per­son, the main con­ve­nience both in an apart­ment and in a coun­try dwelling is the con­stant avail­abil­i­ty of water in the taps. In the coun­try, to pro­vide water sup­ply, many own­ers install an autonomous water sup­ply sys­tem. For a sta­ble sup­ply of water at any time of the day, you can­not do with­out installing a pump­ing sta­tion. What pumps can be used in a coun­try house will be dis­cussed in this arti­cle.

The purpose of the home pumping station

A domes­tic water sta­tion is a com­pact device that, thanks to the pres­ence of auto­mat­ic con­trol, is able to ensure the func­tion­ing of the water sup­ply.

This equip­ment con­sists of:

• suc­tion pump;
• pres­sure tank;
• pres­sure switch;
• pres­sure gauge.

It can be locat­ed in the imme­di­ate vicin­i­ty of the well:

• in the base­ment;
• in mine;
• in a spe­cial room.

Qual­i­ta­tive­ly made auto­mat­ic pump­ing sta­tions for the home do not need spe­cial main­te­nance, as they are reli­able in oper­a­tion. Their oper­a­tion in sub­ur­ban build­ings, the own­ers of which use water from their own sources, makes its con­sump­tion more com­fort­able. As a result, it is pos­si­ble to con­nect wash­ing and dish­wash­ers and house­hold plumb­ing.

Principle of operation

The func­tion­ing of any pump­ing sta­tion depends on the pump, the hydraulic accu­mu­la­tor and the auto­mat­ic sys­tem designed to reg­u­late the pres­sure. After start­ing the device, water is pumped into the pres­sure tank (accu­mu­la­tor), after which it moves through the pipes. It is impor­tant to know how to adjust the water pres­sure with a pres­sure reg­u­la­tor before start­ing any work.

The pump stops when the upper pres­sure lim­it is reached. Fur­ther flow of water occurs due to the pres­ence of pres­sure in the tank until it drops to the low­er lim­it val­ue. Then the pump resumes its work.

This is how a home pump­ing sta­tion pro­vides water sup­ply in a con­stant mode. The pres­sure switch, which must respond to changes, is adjust­ed at the fac­to­ry. To start the device, the required pres­sure is 2 bar and 3 bar to stop. This val­ue is con­trolled by a manome­ter.

Surface pump

The most pop­u­lar pump in sub-irri­ga­tion sys­tems is the sur­face cen­trifu­gal pump. It most ful­ly meets the require­ments for an irri­ga­tion pump. These pumps com­bine high per­for­mance and high pres­sure. All major brands have a wide range of these pumps to cov­er the require­ments of any irri­ga­tion project.

It is called sur­face because it is installed on the sur­face. Only the suc­tion pipe is low­ered into the well, well or oth­er reser­voir. The max­i­mum suc­tion depth is 5–7 meters.

The pow­er of the pumps varies from 300 to 2200 W for sin­gle-phase cur­rent and even more pow­er­ful for 3‑phase cur­rent. Such a pump is installed next to the water tank. The vol­ume of the con­tain­er is select­ed in the project and depends on the area to be irri­gat­ed and the type of sprin­klers. For exam­ple, for a plot of 20 acres with a lawn area of ​​​​about 12 acres, a 1.7 kW pump and a 2000 l tank are used. In autumn, before frosts, the irri­ga­tion sys­tem is purged with air under pres­sure. Spe­cial­ists car­ry out the con­ser­va­tion of the sys­tem using an air com­pres­sor.

Most often you can find pumps mount­ed in the open with­out shel­ters. Remark­ably, pumps oper­ate under rain and sun for many years, but it is still worth con­sid­er­ing that the mate­ri­als from which the pumps are made are not intend­ed for out­door oper­a­tion. Under the influ­ence of ultra­vi­o­let radi­a­tion and pre­cip­i­ta­tion, the pump and automa­tion are in harsh con­di­tions, so it is rec­om­mend­ed to cov­er the pump, for exam­ple, with a visor from rain and sun, or install the pump and automa­tion in a ven­ti­lat­ed cab­i­net.

Purchase of equipment

To ensure an autonomous water sup­ply that ful­ly meets domes­tic needs, it is impor­tant to know how to choose a pump­ing sta­tion for a pri­vate house.

First, you should decide on the main para­me­ters of the pur­chased device, includ­ing:

• pow­er;
• per­for­mance;
• pres­sure tank vol­ume.

Before you choose a pump­ing sta­tion for your home, you need to make some mea­sure­ments and cal­cu­la­tions, and you can do them your­self.

With their help, you will learn:

1. Water injec­tion depth.
2. The dis­tance between the source and points of water intake.
3. Aver­age simul­ta­ne­ous water con­sump­tion at all points. It is assumed that this val­ue is about 4 l / min and in the case of using a show­er 10 — 12 l / min. As a result, it is pos­si­ble to deter­mine the amount of one-time water con­sump­tion by all res­i­dents with­in an hour. The result­ing val­ue must match the per­for­mance of the equip­ment.

There are sev­er­al options for man­ag­ing such a sta­tion:

• auto­mat­ic — the relay starts and turns off the pump after reach­ing the upper and low­er pres­sure val­ues;
• remote;
• man­u­al.

Operating principle

A pump­ing sta­tion for a well or well, which ensures the oper­a­tion of an autonomous water sup­ply sys­tem of a pri­vate house, oper­ates accord­ing to the fol­low­ing prin­ci­ple.

• Water is tak­en from an under­ground source by a pump, after which it enters a hydraulic accu­mu­la­tor, the inter­nal capac­i­ty of which is divid­ed into two halves by a mem­brane.
• The liq­uid pumped out by the pump­ing sta­tion from an under­ground source, enter­ing the accu­mu­la­tor, acts on its mem­brane and stretch­es it, there­by increas­ing the pres­sure in the cham­ber with the air.
• As soon as the flu­id lev­el in the accu­mu­la­tor reach­es its max­i­mum val­ue, the pump auto­mat­i­cal­ly turns off and stops sup­ply­ing water to the tank capac­i­ty.
• When the water in the hydraulic tank becomes less than the min­i­mum lev­el, the water pump­ing sta­tion for a pri­vate house auto­mat­i­cal­ly turns on.

The pump with a hydraulic tank auto­mat­i­cal­ly main­tains pres­sure in the water sup­ply sys­tem at home

For turn­ing on and off the well pump­ing sta­tion, as men­tioned above, the pres­sure switch is respon­si­ble, which is pre-con­fig­ured at the fac­to­ry, but can also be adjust­ed by the con­sumer him­self. As a rule, a pump­ing sta­tion for a pri­vate house is set up by the man­u­fac­tur­er in such a way that it auto­mat­i­cal­ly turns off at a pres­sure val­ue in the sys­tem of 3 bar, and turns on at 2 bar. To con­trol the lev­el of pres­sure that an auto­mat­ic water sup­ply pump­ing sta­tion cre­ates in the pipeline it serves, pres­sure gauges are pro­vid­ed in the design of such an instal­la­tion.

Overheating and dry running protection

Devices designed to sup­ply water, which have pro­tec­tion against dry run­ning and over­heat­ing, have flaw­less func­tion­ing. When there is no water in the source, the sys­tem auto­mat­i­cal­ly turns off, as a result of which the elec­tric motor does not over­heat. This method of pro­tec­tion extends the life of a home water sup­ply sta­tion, but at the same time increas­es its cost.

Popular brands of home appliances

In the domes­tic mar­ket, the most pop­u­lar are:

• Ital­ian prod­ucts Mari­na, Pedrol­lo;
• Ger­man devices TM Karcher, Wilo;
• Gileks is a Russ­ian-made pump­ing sta­tion.

The above equip­ment has the fol­low­ing para­me­ters:

1. Ital­ian devices Mari­na
   . They are designed to lift liq­uid from a depth of 25 meters. Thanks to the cast-iron body, the pow­er­ful sta­tions of this TM can be oper­at­ed in dif­fer­ent con­di­tions. The auto­mat­ic mode of oper­a­tion guar­an­tees a con­stant pres­sure in the water sup­ply. Pro­duc­tiv­i­ty at a pow­er of 1.1 kW is 2400 l / h.
2. Pedrol­lo sta­tions made in Italy
   . They are dis­tin­guished by reli­a­bil­i­ty and the abil­i­ty to pump water from a depth of 9 — 30 meters. This water pump­ing sta­tion for giv­ing with a pow­er of 0.85 — 1.3 kW has a capac­i­ty of 2400 — 9600 l / h.
3. Ger­man instal­la­tions Karcher
   . They are con­sid­ered high-qual­i­ty equip­ment that does not require addi­tion­al main­te­nance due to auto­mat­ic oper­a­tion. Their com­plete set pro­vides the low­ered con­sump­tion of the elec­tric pow­er. Steel stor­age tanks can have a capac­i­ty of 18 to 40 liters. The pow­er of these units is 0.95 kW, and the pro­duc­tiv­i­ty is 3800 l / h.
4. Sta­tions Wilo
   . Prod­ucts of this brand have been on the mar­ket for over 100 years. The com­pa­ny uses the lat­est tech­nol­o­gy. Pump­ing house­hold sta­tions for sum­mer cot­tages and Wilo hous­es are in high demand among con­sumers. They are dis­tin­guished by reli­a­bil­i­ty, trou­ble-free oper­a­tion and easy use, they have pro­tec­tion against dry run­ning, con­den­sa­tion and over­heat­ing. They are sold with a capac­i­ty of 0.55 — 1.6 kW, with a tank of 8 to 60 liters.
5. Pump­ing devices Gileks
   . These sta­tions are the most adapt­ed to work in Russ­ian con­di­tions. The required pres­sure val­ue is main­tained by automa­tion. Units with a capac­i­ty of 0.50 — 1.1 kW have a capac­i­ty of 2700 to 4200 l / h. The vol­ume of the tank can be 24 — 50 liters. The body is made of car­bon steel or plas­tic. Pres­sure con­trol is car­ried out by a manome­ter.

Many own­ers of coun­try hous­es do not have the oppor­tu­ni­ty to enjoy such a bless­ing of civ­i­liza­tion as a cen­tral­ized water sup­ply net­work. This does not mean at all that the only way out in this sit­u­a­tion is to car­ry water from the near­est source in buck­ets. Today it is quite pos­si­ble to equip your own pres­sure water sup­ply. A pump­ing sta­tion will help you with this, auto­mat­i­cal­ly sup­ply­ing water from a well or well.

Decid­ed to buy a pump­ing sta­tion for your home? The mod­ern pump­ing equip­ment mar­ket offers many options — here are ready-made sta­tions, and indi­vid­ual com­po­nents, from which, as from a design­er, you can assem­ble some­thing that best suits your needs.

The choice must be tak­en very respon­si­bly so that you do not have any prob­lems dur­ing the oper­a­tion of the equip­ment.

What is a pumping station

So, as men­tioned above, the whole range of tasks includes ensur­ing the intake of water from the source in the required vol­umes, trans­port­ing it to places of water con­sump­tion with prop­er pres­sure. You can get acquaint­ed in detail with the vari­ety of pump­ing equip­ment for exter­nal sources, with its device, prin­ci­ples of oper­a­tion, instal­la­tion rules, lay­ing lines, insu­la­tion, etc., on the pages of our por­tal, so it makes no sense to return to this top­ic.

There are sev­er­al ways to solve the issue of water sup­ply direct­ly at the points of water intake:

• The pump turns on direct­ly when it is nec­es­sary to sup­ply water, that is, direct­ly — from the source to the con­sumer. This scheme is one of the sim­plest in orga­ni­za­tion, but also the most imper­fect. It com­plete­ly depends on the para­me­ters of the pump­ing equip­ment, and most impor­tant­ly, on the avail­abil­i­ty of pow­er at the time of water intake.

In addi­tion, when automat­ing such a sys­tem, that is, installing a flow sen­sor, the pump will start when­ev­er any tap is opened — no mat­ter whether you need to take a show­er, put the laun­dry on, rinse the plate or even just take a glass of water. Agree that with such fre­quent switch­ing on and off, any pump­ing equip­ment is unlike­ly to last a long time.

Such an approach can be ful­ly jus­ti­fied for, for exam­ple, water­ing a gar­den or for pro­vid­ing water to a very small coun­try house, where the own­ers come only from time to time.

• The pump pumps water into a stor­age tank locat­ed at the top of the house. Thus, there is always a cer­tain mar­gin that reduces the depen­dence of the own­ers on the sta­bil­i­ty of the elec­tric­i­ty sup­ply.

A quite possible, but not without drawbacks, solution is a capacious non-pressure tank

Such a sys­tem is eas­i­er to auto­mate — you can install a float switch that will con­trol the start and stop of the pump when the desired water lev­el is reached in the tank and as it is con­sumed.

How­ev­er, there are seri­ous short­com­ings here as well. First­ly, to install a stor­age tank, it is nec­es­sary to pro­vide a lot of space in the upper part of the house. If this falls into the attic (and this hap­pens most often), then you will also have to deal with high-qual­i­ty ther­mal insu­la­tion of the con­tain­er. Sec­ond­ly, such a dri­ve usu­al­ly has a very impres­sive size.

Placing such a container in the attic will require additional efforts to insulate it.

And third­ly, the usu­al grav­i­ta­tion­al pres­sure of water from the tank may not be enough for the nor­mal oper­a­tion of house­hold appli­ances. And this means that it will be nec­es­sary to install anoth­er pump — to increase the pres­sure, as shown in the dia­gram above. Agree that the instal­la­tion of two pumps is not entire­ly and not always con­ve­nient, the over­all com­plex­i­ty and vul­ner­a­bil­i­ty of the entire sys­tem increas­es.

• Final­ly, the third approach — a pump, sur­face or sub­mersible (deep) pumps water into a mem­brane-type accu­mu­la­tor (pos. 1).

The optimal solution is a hydrostorage membrane tank

Not only is the required sup­ply of water cre­at­ed — it is also under the right pres­sure, in such a way as to ensure the func­tion­ing of all plumb­ing and house­hold appli­ances avail­able in the house. The sys­tem is con­trolled by a pres­sure switch (in this fig­ure — item 2) — it is designed to ensure that the pump is turned off at the moment when the upper lim­it of oper­at­ing pres­sure is reached in the stor­age tank. As water is con­sumed, the pres­sure decreas­es, and when it drops to the low­er thresh­old (which is still slight­ly high­er than the pres­sure required for the cor­rect oper­a­tion of house­hold appli­ances), the pump will be turned on again to replen­ish the spent sup­ply. Thus, the pres­sure in the mem­brane tank is con­stant­ly main­tained in the required oper­at­ing range.

It is obvi­ous that this scheme is the most con­ve­nient to use, opti­mal in terms of ener­gy effi­cien­cy and the life of the pump­ing equip­ment. Such a sys­tem can be assem­bled from sep­a­rate com­po­nents — a pump, a hydroac­cu­mu­la­tor tank, an automa­tion unit with a pres­sure switch. But very often it makes sense to give pref­er­ence to a ready-made tech­no­log­i­cal solu­tion to the prob­lem — a spe­cial instal­la­tion in which all the nec­es­sary ele­ments of the sys­tem are arranged. It is this type of equip­ment that is called pump­ing sta­tions.

An approx­i­mate dia­gram of a pump­ing sta­tion is shown in the fig­ure below:

Schematic diagram of the device of the pumping station

Struc­tural­ly, the pump­ing sta­tion con­sists of the fol­low­ing ele­ments:

Water intake from a well or well is pro­vid­ed by a sur­face pump (pos. 1) of one type or anoth­er — the vari­eties will be men­tioned below. An intake hose (pipe) (pos. 2) is laid to the water source, at the end of which a strain­er (pos. 3) must be installed, which pre­vents the ingress of sol­id sus­pen­sions of unac­cept­able size, and a check valve (pos. 4), which pre­vents water from flow­ing down when off posi­tion of the pump.

The water leav­ing the pump under pres­sure pass­es through anoth­er non-return valve (pos. 5) and a split­ter (pos. 6). An accu­mu­la­tive mem­brane tank (pos. 7), flex­i­ble pip­ing (pos.

to the barometric switch (pos. 9). The relay monitors the level of pressure in the system, ensuring timely operation to transfer power from the 220 V network (pos. 10) to the pumping unit. The pipe (pos. 11) supplies water with the required pressure to the points of consumption: faucets in the kitchen, in the bathroom, in the washbasin (“a” and “b”), the shower stall (“c”), the toilet flush tank (“g ”), washing machine and dishwasher (“d” and “e”), household tap — for watering, cleaning, car washing, etc. (“and”).

Design features of pumping stations

The lay­out of indi­vid­ual ele­ments may vary between man­u­fac­tur­ers and depend­ing on the spe­cif­ic mod­el range. For exam­ple, a baro­met­ric switch (pres­sure switch) may not have a flex­i­ble con­nec­tion, but sim­ply be “plant­ed” on a pipe or on a mem­brane tank. How­ev­er, the prin­ci­ple scheme will not change sig­nif­i­cant­ly from this.

Externally, the layout of the stations can vary quite significantly, but this is only at first glance.

Quite sig­nif­i­cant dif­fer­ences are pos­si­ble in the type of the pump itself.

• Very often, con­ven­tion­al sur­face pumps of the self-prim­ing type are used. These are reli­able and easy-to-install units that do not require com­plex instal­la­tion oper­a­tions. They have a fair­ly high lev­el of per­for­mance, are able to cre­ate a good pres­sure, unde­mand­ing to the puri­ty of the water and to air­ing. The dis­ad­van­tage is the low height of the rise of water from the well — usu­al­ly with­in 6 meters, com­bined with a fair­ly high noise lev­el. So for them it is bet­ter to pro­vide a sep­a­rate room.

The pump has a built-in ejector

• Some self-prim­ing pumps are equipped with a built-in ejec­tor — a spe­cial device that allows you to sig­nif­i­cant­ly increase the depth of water intake from a well or well. up to 10 — 15 meters. True, you have to “pay” for this with even greater noise and a slight decrease in over­all effi­cien­cy — part of the ener­gy is spent on recir­cu­lat­ing water in the ejec­tor loop.
• If the depth of the water in the source is sig­nif­i­cant, then the only alter­na­tive is to use a pump­ing sta­tion with an exter­nal ejec­tor.

An external ejector allows water to be drawn from much deeper depths
The looped movement of water, which sharply increases the suction characteristics of the pump, is organized through the intake and additional hoses, lowered into the water and connected by an ejector nozzle.

Scheme of the recirculation movement of water through an external ejector

Such a con­nec­tion scheme allows you to raise water from con­sid­er­able depths (up to 40 — 45 meters) and trans­fer it over con­sid­er­able dis­tances through pipes from a remote source. The exter­nal loca­tion of the ejec­tor block reduces the noise of the pump­ing sta­tion. There is, of course, a draw­back — such equip­ment is char­ac­ter­ized by high ener­gy con­sump­tion due to reduced effi­cien­cy.

• For shal­low sources, up to 8 — 10 meters, pump­ing sta­tions with a mul­ti­stage type unit are per­fect. The lev­el of noise gen­er­at­ed is very low, so they will not become a source of irri­ta­tion even when installed in a res­i­den­tial part of the house or in the kitchen. At the same time, both the pres­sure and the per­for­mance of the pump reach very sig­nif­i­cant val­ues. True, the com­plex­i­ty of the design pre­de­ter­mines a much high­er price than con­ven­tion­al self-prim­ing units.

A multistage pump has several working chambers in series

Mul­ti­stage pumps can be imme­di­ate­ly dis­tin­guished by the size of the work­ing cham­ber — it has a pro­nounced elon­gat­ed cylin­dri­cal shape, since it con­tains sev­er­al impellers:

• Anoth­er pos­si­ble type of pumps installed on pump­ing sta­tions is vor­tex. The spe­cial design of the work­ing cham­ber and the shape of the wheel cre­ate a tur­bu­lent flow of water, which is char­ac­ter­ized by a high pres­sure, how­ev­er, due to a decrease in the per­for­mance of the device (com­pared to oth­er types). The depth of the fence is small — usu­al­ly with­in 6 ÷ 7 meters.

For shallow sources, a vortex-type pump is quite suitable.

It is advis­able to use such pump­ing sta­tions for small hous­es with a shal­low source — here they will show “in full glo­ry” their effi­cien­cy and qui­et oper­a­tion. Anoth­er com­mon area of ​​their use is as pumps that increase the pres­sure in the domes­tic water sup­ply sys­tem, if such a need aris­es (for exam­ple, a weak pres­sure from the cen­tral water sup­ply line).

The illus­tra­tion below shows a typ­i­cal lay­out of a pump­ing sta­tion in the plumb­ing sys­tem of a pri­vate house.

The place of the pumping station in the plumbing system of a private house

It is pos­si­ble to place a pump­ing sta­tion both in the util­i­ty room of a res­i­den­tial build­ing, and in a spe­cial­ly allo­cat­ed room, for exam­ple, in the base­ment or base­ment floor. For a sta­tion­ary instal­la­tion, it is impor­tant to pay atten­tion to lay­ing the pipeline from the well to the house (shown by an orange arrow) at a depth below the freez­ing lev­el of the soil and with its high-qual­i­ty ther­mal insu­la­tion.

Pay atten­tion to a num­ber of let­ters with arrows shown in the dia­gram. These are the val­ues ​​that we will need in the future to deter­mine the required para­me­ters of the pump­ing sta­tion — the depth of water intake, the height of the pres­sure it cre­ates, and the per­for­mance of the sys­tem.

Choosing a pumping station

The read­er has already famil­iar­ized him­self with some para­me­ters for choos­ing a pump­ing sta­tion above. In par­tic­u­lar, they talked about the type of the pump itself and relat­ed fac­tors — noise, effi­cien­cy. Now let’s look at a few fun­da­men­tal per­for­mance char­ac­ter­is­tics that must be tak­en into account when buy­ing pump­ing equip­ment.

Maximum water intake depth

The selec­tion of a pump­ing sta­tion for this para­me­ter should be based on the actu­al char­ac­ter­is­tics of the water source and its dis­tance from the instal­la­tion site of the equip­ment.

The fun­da­men­tal dis­tance is the dis­tance in height from the water sur­face in the well to the axis of the pump (shown in the dia­gram with red arrows and the let­ter G). It is cus­tom­ary to take the dynam­ic lev­el of the well as a ref­er­ence point, that is, the aver­age lev­el with a con­stant water intake for at least 24 ÷ 48 hours. The sta­t­ic lev­el that water reach­es if there was no selec­tion from the well dur­ing the last one or two days can give a sig­nif­i­cant error in the cal­cu­la­tions.

The val­ues ​​of the dynam­ic and sta­t­ic source lev­el must be known to each host. They are deter­mined empir­i­cal­ly, by con­duct­ing mea­sure­ments over a suf­fi­cient­ly long peri­od. By the way, the deb­it of the well (well) large­ly depends on these indi­ca­tors, which will also become one of the deter­min­ing cri­te­ria when choos­ing pump­ing equip­ment.

If the water source is locat­ed in close prox­im­i­ty, lit­er­al­ly a few meters from the pump­ing sta­tion, then this val­ue of G may be quite suf­fi­cient. Of course, in order for the pump not to work at the lim­it of its capa­bil­i­ties, about 10 — 15% of the reserve should be added, espe­cial­ly since the water will also have to over­come the resis­tance of the check valve. But if a sig­nif­i­cant hor­i­zon­tal sec­tion is also being laid (in the dia­gram — blue arrows and the let­ter L), then it should also be tak­en into account — there will also be loss­es due to the hydraulic resis­tance of the pipes.

In the case when a pipe with a diam­e­ter of 1 inch is being laid, then we can pro­ceed from the ratio of 1 meter of ver­ti­cal = 10 meters of hor­i­zon­tal pipe lay­ing. Usu­al­ly pump­ing house­hold sta­tions are equipped with a cor­re­spond­ing branch pipe of this diam­e­ter. But if a ¾ inch pipe is laid, then it would be more cor­rect to take a ratio of 1: 7. It is unlike­ly that any­one will think of using pipes of a small­er diam­e­ter — this is com­plete­ly unrea­son­able.

The mate­r­i­al used to man­u­fac­ture pipes is also impor­tant — in steel, the hydraulic resis­tance is sig­nif­i­cant­ly greater than in plas­tic ones.

To make it eas­i­er for the read­er, below is a cal­cu­la­tor that will help you quick­ly cal­cu­late the required val­ue of the depth of water intake, tak­ing into account the laid pipeline and the required mar­gin.

Water pressure generated by the pumping station

The pump­ing sta­tion is designed to pro­vide the nec­es­sary water pres­sure at any of the points of con­sump­tion, up to the most remote, tak­ing into account its fea­tures, that is, the min­i­mum pres­sure required for cor­rect oper­a­tion. If it is just a mix­er, then 1 ÷ 1.5 atmos­pheres will be enough there (respec­tive­ly, 10 ÷ 15 meters of water col­umn). But for some appli­ances, for exam­ple, for a show­er stall, a hydro­mas­sage bath, an instan­ta­neous water heater or oth­er house­hold appli­ances, more is required. This para­me­ter must be spec­i­fied in the tech­ni­cal spec­i­fi­ca­tions of the prod­uct.

Be sure to take into account the dif­fer­ence in the heights of the loca­tion of the pump­ing sta­tion and the point of water intake (in the dia­gram — green arrows and the let­ter H), the length of the hor­i­zon­tal sec­tions of the inter­nal water sup­ply net­work, the mate­r­i­al and diam­e­ter of the pipes.

Below is a cal­cu­la­tor that will allow you to avoid com­plex cal­cu­la­tions. Just enter the request­ed val­ues ​​— and get the result.

The oper­at­ing range of the accu­mu­lat­ing mem­brane tank is also direct­ly relat­ed to the pres­sure gen­er­at­ed. In the doc­u­men­ta­tion of some mod­els, it is indi­cat­ed by two val­ues ​​— the upper and low­er lim­its for the oper­a­tion of the baro­met­ric relay. Mod­els are avail­able in which the adjust­ment of the water pres­sure val­ues ​​in the sys­tem can be car­ried out in a cer­tain range and inde­pen­dent­ly. As a rule, for visu­al con­trol, the pump­ing sta­tion is equipped with a barom­e­ter.

Pump station performance

The next impor­tant para­me­ter is how much the pump­ing sta­tion will be able to cope with the flow of water. Here you can count in dif­fer­ent ways, for exam­ple, start­ing from the aver­age dai­ly con­sump­tion for each fam­i­ly mem­ber. How­ev­er, it seems more cor­rect to cal­cu­late peak con­sump­tion, which pro­vides for the pro­vi­sion of water to all points of water intake in that unlike­ly, but still pos­si­ble sit­u­a­tion, when all of them are involved at the same time.

It is enough to sum up the val­ues ​​for all the water points in the house, take into account the cor­rec­tion fac­tor for their num­ber and con­vert to liters per minute or per hour (usu­al­ly these are the para­me­ters indi­cat­ed in the pass­ports of pump­ing equip­ment).

Qmax = ∑Q(1÷x) × Kx

Qmax — peak demand.

∑Q(1÷x) is the sum of water dis­charges from all draw-off points, from 1 to x.

Kx is a cor­rec­tion fac­tor that takes into account the total num­ber of water con­sump­tion points (x).

Kx is deter­mined by the fol­low­ing expres­sion:

Kx = 1 / √ (x‑1).

It should be cor­rect­ly under­stood that the val­ue obtained is indica­tive. It should not exceed the actu­al deb­it of the well (well) in any way in order to pre­vent air­ing of pump­ing equip­ment or shal­low­ing and silt­ing of the water source. If the actu­al flow rate should be less (based on the para­me­ters of the source), then nev­er­the­less, when choos­ing, one should pro­ceed from it. Well, at home, you will have to solve the issue of con­sump­tion by any “admin­is­tra­tive” mea­sures in order to exclude the pos­si­bil­i­ty of simul­ta­ne­ous­ly open­ing all points of water intake.

Supply voltage and power consumption of pumping equipment

These selec­tion cri­te­ria are not so impor­tant from the point of view of the oper­a­tion of the pump­ing sta­tion itself, but from the point of view of lay­ing an appro­pri­ate pow­er line for it.

The vast major­i­ty of domes­tic pump­ing sta­tions are equipped with elec­tric dri­ves oper­at­ing on a sin­gle-phase AC 220 V. Very rarely, but still there are sta­tions with three-phase motors (380 V) — these are pow­er­ful units designed for long-term and high-per­for­mance work to pro­vide water to a large man­sion or a whole ris­er at the entrance of a high-rise build­ing.

The pow­er of domes­tic pump­ing sta­tions usu­al­ly ranges from 500 to 2000 watts. In accor­dance with this, the cross sec­tion of the wires of the pow­er line, the type of cir­cuit break­er and safe­ty device (RCD) will be select­ed.

As a rule, mod­ern pump­ing sta­tions are also equipped with their own emer­gency shut­down sys­tems — from over­heat­ing, “dry” run­ning (in the absence of water in the source or in the intake hose), short cir­cuit or break­down to ground, pow­er surges, etc.

Hydrostorage tank volume

The larg­er the vol­ume of the mem­brane tank, the less often the pow­er plant will turn on, and the longer the pump­ing sta­tion itself will last. True, an increase in vol­ume is always accom­pa­nied by an increase in the dimen­sions and weight of the entire instal­la­tion (not every­where there is enough free space for its instal­la­tion), and an increase in the cost of the sta­tion. There­fore, some kind of “gold­en mean” is need­ed.

• The most pop­u­lar, accord­ing to sales sta­tis­tics, are pump­ing sta­tions with a tank with a capac­i­ty of 24 liters — this is quite enough to pro­vide water to a coun­try house or orga­nize an autonomous water sup­ply sys­tem for the needs of 1–2 peo­ple.

The most “running” are pumping stations with a relatively small 24-liter membrane tank

• For a fam­i­ly of 3 ÷ 5 peo­ple, sub­ject to con­stant use, a 50-liter hydraulic accu­mu­la­tor is usu­al­ly enough — the engine will not turn on too often, and in addi­tion, a quite impres­sive sup­ply of water is cre­at­ed that can help out in the event of a sud­den pow­er out­age.
• If 6 or more peo­ple live in the house, then, of course, you need to think about a more capa­cious accu­mu­la­tor — about 100 liters.

By the way, in some brand­ed salons work­ing with brand­ed prod­ucts, it is prac­ticed to com­plete the pump­ing sta­tion with an accu­mu­lat­ing capac­i­ty of the cus­tomer’s choice, based on spe­cif­ic needs.

If you look at the cat­a­logs of pump­ing sta­tions offered for sale, you can find instal­la­tions with very small mem­brane tanks — some­times the vol­ume is only 2 liters. It is clear that it is at least naive to seri­ous­ly con­sid­er such a con­tain­er as a hydraulic accu­mu­la­tor — it serves, rather, to main­tain the required pres­sure in the sys­tem, smooth­ing out hydraulic shocks. But the fre­quen­cy of start­ing the pump with such a tank will be very high, and the appar­ent advan­tages in the cost of the sta­tion will be absolute­ly not jus­ti­fied — such a pump is unlike­ly to last for a long time.

Design features

• Pump­ing sta­tions also dif­fer in the mate­r­i­al of man­u­fac­ture of the hous­ing.

— Pumps with cast iron cas­ings are dis­tin­guished by a rel­a­tive­ly low noise lev­el and quite afford­able price.

The dis­ad­van­tage is the large mass of the prod­uct. In addi­tion, although cast iron itself has good cor­ro­sion resis­tance, rusty deposits can form in water, espe­cial­ly with pro­longed con­tact with­out move­ment. Man­u­fac­tur­ers are try­ing to solve this prob­lem by apply­ing a spe­cial pro­tec­tive coat­ing to the inner walls. When choos­ing a pump­ing sta­tion with a cast-iron cas­ing, this aspect should be paid atten­tion to.

- Stain­less steel cas­es do not rust and are sig­nif­i­cant­ly lighter in weight.

How­ev­er, they also have a sig­nif­i­cant draw­back — such pump­ing sta­tions are the most “noisy” dur­ing oper­a­tion. In addi­tion, their cost is sig­nif­i­cant­ly high­er than devices with cast-iron cas­es.

- Mod­els made of spe­cial high-strength plas­tic are gain­ing more and more pop­u­lar­i­ty.

They, in fact, com­bine the advan­tages of both types list­ed above — they have a low noise lev­el and per­fect inert­ness in rela­tion to water — they do not change its com­po­si­tion in any way. Many pump­ing sta­tions in plas­tic design have addi­tion­al anti-vibra­tion pro­tec­tion.

• When buy­ing, you should pay atten­tion to the pres­ence and place­ment of mount­ing brack­ets (stands), the method of mount­ing the sta­tion on the instal­la­tion site in the select­ed loca­tion.
• The degree of pro­tec­tion of the body of the device from dust and water splash­es is impor­tant. The high­er the IP index, the bet­ter the sta­tion. The best choice would be to pur­chase an instal­la­tion of at least IP54 class — this is almost com­plete pro­tec­tion of the elec­tri­cal part of the pump from dust and water splash­es.
• A con­ve­nient addi­tion will be the built-in water fil­ter — this will com­plete­ly elim­i­nate the wear or fail­ure of the pump due to the pos­si­ble ingress of sol­id sus­pen­sions from the source into the work­ing cham­ber. How­ev­er, noth­ing pre­vents you from installing a coarse fil­ter at the inlet and on your own.

• And, final­ly, in the event that the pump­ing sta­tion, accord­ing to the own­ers, should have a cer­tain mobil­i­ty — it is planned to move it from place to place as need­ed, then you should pay atten­tion to the mass of the prod­uct, its equip­ment with a car­ry­ing han­dle, the con­ve­nience and ease of quick prepa­ra­tion for work and trans­fer to the “stowed posi­tion”.

Brief overview of models of domestic pumping stations

Of course, the rat­ing of the man­u­fac­tur­er should be con­sid­ered the most impor­tant cri­te­ri­on for choos­ing pump­ing equip­ment. Such a pur­chase can­not be called cheap, it is made for sev­er­al years in advance, and it would not be entire­ly rea­son­able to give mon­ey for an unknown prod­uct with vague war­ran­ty oblig­a­tions.

Of the domes­tic brands, we can safe­ly rec­om­mend pump­ing sta­tions — they are per­fect­ly adapt­ed specif­i­cal­ly to Russ­ian oper­at­ing con­di­tions. The instal­la­tions of the Vikhr and Zubr brands have a good rep­u­ta­tion — these are also Russ­ian devel­op­ments, how­ev­er, they are main­ly let in at the pro­duc­tion facil­i­ties of neigh­bor­ing Chi­na. How­ev­er, Chi­nese assem­bly is prac­ticed and many Euro­peans in the pro­duc­tion of pump­ing equip­ment are always con­sid­ered Ger­man, Gar­de­na, Grund­fos, Metabo, Kärcher. High-qual­i­ty reli­able pump­ing sta­tions of Ital­ian, “Pedrol­lo”, “Ergus” are in high demand.

When choos­ing a spe­cif­ic man­u­fac­tur­er, it will nev­er be out of place to clar­i­fy how ser­vice main­te­nance is orga­nized in a giv­en region, whether there are spe­cial­ized cen­ters where you can get tech­ni­cal sup­port. It will be very dis­ap­point­ing if the pur­chased pump­ing sta­tion in your area is con­sid­ered “exot­ic”, and any even tri­fling spare part will have to be ordered from some­where far away.

Key ele­ments affect­ing the oper­at­ing life of a pump­ing sta­tion:

• Work­ing wheel;

  

• sta­tor wind­ing;
• flange, as well as the qual­i­ty of the mem­brane and the reli­a­bil­i­ty of automa­tion.

Depend­ing on the type of elec­tron­ic-mechan­i­cal unit, there are types of pump­ing sta­tions and the prin­ci­ple of their oper­a­tion.

The clas­sic design most famil­iar to home­own­ers based on pres­sure switch­es. The water pres­sure switch is a water sup­ply sys­tem automa­tion device that auto­mat­i­cal­ly turns on and off the pump or pump­ing sta­tion when the water pres­sure changes. The relay has upper and low­er thresh­olds. When the water pres­sure drops to the low­er thresh­old, the pres­sure switch clos­es its con­tacts and sup­plies pow­er to the pump, there­fore, turns it on. When the pres­sure reach­es the upper thresh­old, the relay opens the con­tacts and de-ener­gizes the pump, turns it off. This mechan­i­cal device, with its high preva­lence, is the most vul­ner­a­ble con­trol of pump­ing sta­tions, as it is com­plete­ly unpro­tect­ed from var­i­ous emer­gency sit­u­a­tions. There is anoth­er type of pump­ing sta­tions based on elec­tron­ic units of var­i­ous func­tion­al­i­ty.

Their main dif­fer­ence from sta­tions with relays is pro­tec­tion against most emer­gency sit­u­a­tions in the sys­tem:

• “dry run­ning” — work with­out water;
• impeller jam­ming;
• low volt­age in the mains;
• poor per­for­mance of the source, low­er­ing the water lev­el or its dynam­ic fluc­tu­a­tions;
• decrease in pres­sure in the accu­mu­la­tor;
• block­age.

There are man­u­fac­tur­ers who spe­cial­ize in the pro­duc­tion of such pump­ing sta­tions. The most famous of them are AQUAROBOT Adap­tive and Uni­ver­sal.

The uni­ver­sal sta­tion, in addi­tion to the relay, con­tains a flow sen­sor in its struc­ture. The prin­ci­ple of oper­a­tion is sim­i­lar to sta­tions with a relay. When the set max­i­mum pres­sure val­ue in the sys­tem is reached, the sta­tion turns off, and when the pres­sure drops to the min­i­mum, it turns on. But, if for some rea­son the pump can­not cre­ate the set shut-off pres­sure in the sys­tem (lack of water in the suc­tion line, low volt­age of the mains, jam­ming of the pump impeller, improp­er instal­la­tion of the sta­tion, etc.), the pump is con­trolled by the TURBI flow sen­sor.

Adap­tive sta­tions are equipped with an automa­tion unit with a low­er pres­sure thresh­old sen­sor and a flow sen­sor, as well as a restart func­tion in case of an emer­gency stop. In the absence of water, the sta­tion will go into pre-alarm mode, then it will make 6 auto­mat­ic test runs last­ing 30 sec­onds each — after 5, 20, 60 min­utes, then after 6, 12 and 24 hours. If water appears dur­ing any of the test runs, the sta­tion will auto­mat­i­cal­ly start and go into pump­ing mode.

This type of sta­tion is con­sid­ered the most reli­able, pro­longs the life of the pump and the sys­tem itself, and also saves the con­sumer from unnec­es­sary trou­ble.

Nuances of choice

The process of choos­ing a pump­ing sta­tion for a sum­mer res­i­dence or your own home will not become dif­fi­cult if you take into account a num­ber of fea­tures that affect its oper­a­tion:

1. Per­for­mance. Prod­ucts of com­pa­nies known among con­sumers on the pos­i­tive side do not cre­ate prob­lems in work.
2. Man­u­fac­tur­ing mate­r­i­al. Devices in the man­u­fac­ture of which car­bon steel is used have a long ser­vice life com­pared to plas­tic prod­ucts.
3. Cor­re­spon­dence between tech­ni­cal para­me­ters and required char­ac­ter­is­tics. This applies to the size of the stor­age tank, the per­for­mance of the equip­ment and the depth of the aquifer.
4. The pres­ence of a sys­tem that pro­tects against the pos­si­bil­i­ty of over­heat­ing and dry run­ning, which extends the ser­vice life.

What to look for when choosing?

The main prob­lem that the dacha own­er faces is which pump­ing sta­tion will be suit­able for the dacha. In order not to make a mis­take with the choice, you should lis­ten to the rec­om­men­da­tions of experts.

How to choose a pump­ing sta­tion for a sum­mer res­i­dence:

• First of all, you need to cal­cu­late in advance the amount of water that you plan to spend while liv­ing in the coun­try. Based on the results of the cal­cu­la­tions, it is nec­es­sary to make a choice in favor of a tank of a suit­able vol­ume. If you need water not only for domes­tic needs, but also for water­ing plants, then you should choose a larg­er con­tain­er.
• It is also nec­es­sary to deter­mine the per­for­mance of the pump­ing sta­tion. The greater the need for water from the own­er of the site, the more pow­er­ful pump­ing sta­tion you need to choose for your water sup­ply sys­tem.
• Anoth­er point that requires atten­tion is the depth of the aquifer. This para­me­ter is also impor­tant, since it affects not only the choice of the type of pump­ing sta­tion, but also oth­er pow­er indi­ca­tors.

While in the store and choos­ing a pump­ing sta­tion for your dacha, the main atten­tion should be paid to para­me­ters such as per­for­mance and pres­sure. In addi­tion, the pres­sure that the sta­tion can pro­duce dur­ing oper­a­tion, tak­ing into account loss­es, is impor­tant. They should be under­stood as a decrease in water pres­sure as it pass­es through pipes.

When decid­ing which mini-sta­tion to choose, it is nec­es­sary to pay atten­tion to such a moment as the mate­r­i­al of man­u­fac­ture of the pump hous­ing and tank. Most mod­els are made of ordi­nary or stain­less steel, as well as cast iron. The advan­tages of a stain­less steel case is that it is resis­tant to cor­ro­sion process­es. This allows the pump to be installed out­doors. The cast iron pump runs qui­et­ly. Its instal­la­tion can be per­formed in one of the premis­es of the house. How­ev­er, dur­ing oper­a­tion it is nec­es­sary to peri­od­i­cal­ly check the integri­ty of the coat­ing.

Many mod­ern mod­els con­tain var­i­ous addi­tion­al fea­tures. For exam­ple, the pump may have a water fil­ter or a dry run­ning sen­sor. The sec­ond func­tion is espe­cial­ly impor­tant, because in the absence of water sup­ply, thanks to this option, the pump is turned off, which elim­i­nates its over­heat­ing and pre­ma­ture fail­ure.

It should be under­stood that the pur­chase and instal­la­tion of pump­ing equip­ment for autonomous water sup­ply sys­tems is quite an expen­sive plea­sure. There­fore, do not rush to pur­chase it. The task of buy­ing a pump for the coun­try must be approached thor­ough­ly. It is bet­ter to spend mon­ey on a qual­i­ty device of the required pow­er than to suf­fer with an unre­li­able and weak device. Even before buy­ing, you should decide which func­tions in the pump­ing sta­tion are the most impor­tant for you, and which ones you can do with­out.

When choos­ing a mini-pump­ing sta­tion for your site, atten­tion should be paid to such a para­me­ter as the source of water. Pumps can be installed on a well or on a well. If the dis­tance to the water source is too large, then in this case you will have to spend mon­ey on bore­hole pump instal­la­tion.

When choos­ing a pump­ing sta­tion for a sum­mer res­i­dence, atten­tion should also be paid to the accu­mu­la­tor. If the num­ber of peo­ple liv­ing in the house is small, and the num­ber of taps is insignif­i­cant, then it will be enough to pur­chase a 24-liter hydraulic tank. If the house has sev­er­al sources of water intake at once, then in this case the best choice would be a 50-liter hydraulic accu­mu­la­tor. If the own­er did not plan to use many sources of water, and addi­tion­al ones appeared dur­ing the oper­a­tion of the equip­ment, then this is not a big prob­lem. You can install an addi­tion­al accu­mu­la­tor with a capac­i­ty of 24 liters.

Advantages and disadvantages

If the selec­tion of the pump­ing sta­tion is done cor­rect­ly, it will be able to ful­ly feed the autonomous water sup­ply sys­tem. In addi­tion to pump­ing water, it also main­tains the required pres­sure.

Among the ben­e­fits are:

• the use of mate­ri­als that are not sub­ject to cor­ro­sion;
• long peri­od of oper­a­tion;
• the pres­ence of a sys­tem that pro­tects against dry run­ning;
• com­plete instal­la­tion, after which the equip­ment is ready for use;
• reduced noise lev­el dur­ing oper­a­tion;
• ener­gy con­sump­tion in econ­o­my mode;
• avail­abil­i­ty of water in the tank.

There are also dis­ad­van­tages:

1. Most coun­try pump­ing sta­tions are capa­ble of lift­ing liq­uid from a depth of 8 — 9 meters.
2. When putting the equip­ment into oper­a­tion, the hose is filled with water and the pres­sure switch is adjust­ed.
3. Sen­si­tiv­i­ty to the pres­ence of var­i­ous con­t­a­m­i­nants, so you need to install a fil­ter.
4. The need to con­trol the lev­el of pres­sure.

Installation of equipment

A large or small pump­ing sta­tion is deliv­ered to the dis­tri­b­u­tion net­work assem­bled, ful­ly pre­pared for oper­a­tion. The buy­er only needs to con­nect the equip­ment to the water-car­ry­ing struc­ture and the suc­tion pipeline. Before this, a check valve is installed on the suc­tion pipe — it will retain water in the event of a pow­er out­age. A detailed dia­gram of con­nect­ing a pump­ing sta­tion in a pri­vate house allows you to do every­thing your­self.

If there are mechan­i­cal inclu­sions, a strain­er is mount­ed. When installing the unit, shock-absorb­ing mate­r­i­al is used to help reduce the vibra­tion that occurs dur­ing its oper­a­tion. The instal­la­tion must be ground­ed. After the sta­tion is ful­ly con­nect­ed to the water sup­ply, it is nec­es­sary to fill the suc­tion pipeline and the pump hous­ing with water using the fill­ing plug.

After check­ing the tight­ness of the con­nec­tion nodes, the pres­sure lev­el is pumped through the fit­ting to the val­ue rec­om­mend­ed by the man­u­fac­tur­er. Only after that the unit is con­nect­ed to the pow­er sup­ply. The room where the sta­tion is locat­ed must be heat­ed. When placed in a mine, the cov­er is made dou­ble and insu­lat­ed.

Types and types, connection features

The main work­ing part of this equip­ment is the pump. It is its type that deter­mines their main tech­ni­cal char­ac­ter­is­tics. Let’s talk about pumps.

Surface and submersible

Most of the sta­tions sup­plied from fac­to­ries in assem­bled form are equipped with sur­face pumps. They are installed on the same frame with a hydraulic accu­mu­la­tor and a con­trol group. A pipeline is con­nect­ed to the pump, which is low­ered into a source — a well, a well, etc. This option is good because it can be used in nar­row wells — the pipe diam­e­ter can be from 32 mm, which is nor­mal even for the nar­row­est well. But such sys­tems can raise water from a depth of about 7–10 meters.

Water sup­ply scheme of a pri­vate house with a pump­ing sta­tion with a sur­face pump

When installing such equip­ment, a fil­ter and a check valve must be installed at the end of the sup­ply pipeline immersed in water. A fil­ter (mesh) is required, since pumps are demand­ing on water qual­i­ty, and a check valve pre­vents water from drain­ing while pump­ing is in progress. With­out these two parts, the sys­tem works inef­fi­cient­ly.

If the well is deep, a sub­mersible pump or instal­la­tion with an exter­nal ejec­tor is required. In this case, the ejec­tor is low­ered into the well or well, two hoses are con­nect­ed to it. The rest of the equip­ment is on the sur­face. With such a sys­tem, water can rise from a depth of 40–45 meters.

A pump­ing sta­tion with an exter­nal — sub­mersible ejec­tor allows you to get water from deep wells or wells up to 40–45 m deep

The dis­ad­van­tage of this sys­tem is that it does not like the pres­ence of air in the pipes (hoses), which is why start­ing the sys­tem is a trou­ble­some and respon­si­ble event.

Quiet and noisy

The inter­nal design of the pumps also dif­fers. The noise lev­el dur­ing oper­a­tion depends on their struc­ture.

• Vor­tex. The suc­tion force is cre­at­ed by the blades inside the body. These pump­ing water sup­ply sta­tions for the home are silent or very qui­et, but they can only raise water from a shal­low depth. They can and should be installed in res­i­den­tial build­ings: they real­ly do not like tem­per­a­ture changes, and when they freeze, they fail.
• Cen­trifu­gal pumps make a lot of noise dur­ing oper­a­tion, but they pump water from decent depths and can oper­ate at dif­fer­ent tem­per­a­tures, there­fore they can be installed in spe­cial­ly equipped pits.

Some Tips

Before choos­ing a pump­ing sta­tion, it is desir­able:

1. Decide on the pur­pose of buy­ing a device, since its pow­er and oth­er para­me­ters depend on it.
2. Per­form the cal­cu­la­tions that are need­ed to com­pare with the tech­ni­cal para­me­ters of the unit.
3. Choose a mod­el accord­ing to the advice of experts.
4. Keep in mind that equip­ment with a met­al case has a high­er price com­pared to plas­tic mod­els, but it will pay off due to a long peri­od of oper­a­tion and sav­ings in ser­vice costs.

The device must be installed accord­ing to the man­u­fac­tur­er’s instruc­tions.

B. Station Capabilities

This ques­tion is much more dif­fi­cult. What to con­sid­er?

Features of the well (well)

• Depth of water intake.
• Her sta­t­ic lev­el.
• Deb­it (in oth­er words, fill­ing rate).

Pump features

Installation scheme
Someone looks at power, someone is interested in performance. Of course, there will not be a single recommendation, since these parameters are interrelated. Basically, all budget devices at a depth of 10 m will provide a fence. Here you need to focus on a combination of a number of factors — pressure (pillar height), reservoir capacity, intensity of water use, station distance from the source, and some others.

The issue of per­for­mance is worth not­ing espe­cial­ly. In prin­ci­ple, this is the amount of liq­uid that this device is capa­ble of pump­ing over a cer­tain peri­od of time. But it makes no sense to take the mod­el “with a mar­gin”. First­ly, do not for­get about the elec­tric / ener­gy meter, which will “turn” faster. Sec­ond­ly, the more pow­er­ful the pump, the faster the well will “drain”, and this is no longer “very good”.

How to proceed?

The eas­i­est option is to talk to the own­ers of the plots in your hol­i­day vil­lage. What kind of pumps they have at the sta­tions and every­thing else. Where is the water pumped from, enough for irri­ga­tion or not. There are many nuances, but it is pos­si­ble to come to a com­mon denom­i­na­tor.

If you need an accu­rate cal­cu­la­tion, you will have to con­tact the experts. But is it nec­es­sary, giv­en that we are not talk­ing about such an expen­sive pur­chase as a car or an apart­ment? In prin­ci­ple, the man­ag­er in the store (if he is real­ly knowl­edge­able) will be able to help you make the right choice. But for this he will need the ini­tial data (depth and deb­it — in the first place). Those who are inter­est­ed in how to deter­mine the lev­el of ground­wa­ter will find a detailed answer here.

Cal­cu­late every­thing your­self. Approx­i­mate data: for irri­ga­tion — up to 1.5 m³ / hour. As they say, “behind the eyes.” This is equiv­a­lent to a capac­i­ty of about 3 l/s. Such a char­ac­ter­is­tic is reflect­ed in the pass­port of the device. And dur­ing breaks, it is enough to quick­ly fill the spare con­tain­er.

Prac­tice shows that for a sum­mer res­i­dent who comes to the site to engage in gar­den­ing / gar­den­ing, and not wash­ing, swim­ming in the pool, etc., a sta­tion with a capac­i­ty of 0.7 — 1.2 kW is quite enough.

Price

Quite a log­i­cal con­clu­sion to the sto­ry is to answer the ques­tion, how much does a “dacha” sta­tion mod­el cost approx­i­mate­ly? Nat­u­ral­ly, speak­ing of inex­pen­sive mod­els, it is advis­able to pay atten­tion to Russ­ian-made prod­ucts. It is rare among import­ed ones to be both good and cheap at the same time. Is it Chi­nese instal­la­tions, but this is more like­ly for “extreme lovers”.

Mean­while, there are also our, domes­tic, units that work reli­ably and, most impor­tant­ly, the own­ers do not have any prob­lems with spare parts and repair of this equip­ment.

“Vortex”

Under this brand, there are many installations on sale that differ mainly in characteristics. For example, the model of the ASV-800/19 series, costing 7,359 rubles, provides a capacity of 60 l / min with a maximum liquid intake depth of 9 m (power 0.8 kW, hydraulic accumulator 19 liters). It will fully fulfill its functions if there is no more than 25 — 30 m between it and the source. What else is needed for a summer residence? And this despite the fact that the power supply is 1 f 220 V (from a conventional outlet).

A more pow­er­ful mod­el (for exam­ple, ASV-1200 / 24N) for 1.2 kW with a 24-liter bat­tery costs about 8,650 rubles.

And these are only 2 units from the entire range of “Whirl­winds”. The choice is real­ly big, for every taste.
