The submersible type of well pumps is most often used in the country, although this is not the only option. Considering that generally the depth of wells in the areas does not exceed 8–10 m (with a larger value of this parameter, it is more economically profitable to drill mines), it makes no sense to consider other varieties. The difficulty is that even submersible models are different, and sometimes it’s difficult to choose best option For dacha use. So let's look at this in more detail.

Main characteristics

We will focus on the fact that there is no permanent resident on the site big family, and the owners come to the dacha only during the season (the most common option).

Pump type

In this case, you need to pay attention to vibration pumps. Their main advantage is ease of operation and unpretentiousness. For use in the period spring-summer-early autumn - optimal solution, especially since they are cheaper than their analogues. Although centrifugal pumps are more efficient, they have a number of significant disadvantages. Therefore, their installation and operation (including repairs) are more expensive. For a small dacha there is no point in purchasing one.

Performance

Only a professional can perform accurate calculations. Many factors are taken into account - the total length of the pipes (and their cross-section), the number of water collection points, the immersion depth of the pump and a number of others. Based on this, they focus on indicators such as pressure and power (by the way, they are interrelated).

In relation to a small dacha of several hundred square meters, where the owners appear only periodically (for watering and caring for the plot), so as not to “overload” the reader with formulas and coefficients, we can give the following general recommendation– a model with a power of 1.2 (±0.2) kW is sufficient. Although sometimes 0.3 is quite enough. It is necessary to take into account the specifics of watering, then it will become more clear what to buy.

Perhaps these are all the features of choice if you mean purchasing a small-sized pump without permanent residence. Otherwise, the reader should read the materials on issues related to the water supply system. This is a separate and rather voluminous topic.

Before you go shopping, you need to clearly understand some points, since the seller is absolutely not informed what kind of well is on the site and how it is used. What to consider?

• Required volume of water intake. For what - if watering the territory, then for how long, or only for domestic needs, and so on. This determines the required performance.
• Length and configuration of the highway.
• Well parameters (depth, filling capacity, etc.).
• Frequency of operation (all year round or only during the season).

The market offers products from different manufacturers. For example, models under the ESPA brand (the head office is located in Spain) have proven themselves well. There are also many other high-quality imported pumps (for example, “WILO”, “KERSELF”).

However, we can advise you to pay attention to domestic products. And not only from a sense of patriotism, but also from a practical point of view.

• They are cheaper foreign analogues. Already a plus.
• Russian models are quite simple in design and unpretentious in operation. Repairing them on your own, as well as finding spare parts, does not cause any difficulties. Plus number 2.

Based on this, we will consider several domestic pumps.

*Prices are indicated for the Moscow region.

"Aquarius"

Available in several modifications. The “BTsPE 0.5” series with a power of 0.65 kW creates a pressure of up to 40 m with a productivity of 1.8 m³/h. It is clearly not suitable for simultaneous, “fan” irrigation of the site, but alternate irrigation of segments of the territory will provide. In principle, most summer residents organize their work this way, opening/closing the corresponding valves on the pipes.

Price – from 10,050 rubles.

"Gileks"

The Vodomet - 150/30 series is more powerful - 0.9 kW. At a head of up to 30 m, the productivity is about 150 l/min. Able to work in turbid water (fractions - no more than 2.5 mm).

Price – from 8,165 rubles.

"Baby"

The cheapest, and therefore most popular among summer residents, is a submersible pump. For example, the model of the “P 1500” series has a lower intake pipe (up to 10 m). Power – 0.24 kW; 25 l/min; immersion depth – up to 3 m. Weight – 3.2 kg. It is unpretentious in operation and for a small dacha, taking into account the cost, the best option.

Price – from 1,510 rubles.

Well, what exactly to buy, decide for yourself, dear reader. The choice is huge now.

Which pump to choose for a 10 meter well

Selecting a submersible pump usually takes a lot of time from summer residents, because so many incomprehensible numbers, designations and manufacturers fall out of nowhere. And how many stupid articles have been written... it’s impossible to count, but this is not one of them.

We have already told you how to choose a pump for a well; it was a general article, not tied to a specific depth.
Now we will quickly and clearly explain to you which pump is better for a 10-meter or 15-meter well; there is not much difference here.

Choosing a pump for a well 10 meters deep

Let's consider the situation: you have drilled a well 10 meters deep, and you want to choose a deep-well pump for it.
The first and most important thing you need to do is find the well's passport and look at the drilling organization's recommendations for choosing a pump. If there is no passport or the pump parameters are not indicated there, then we will continue.

It is important to know the diameter of the casing pipe in order to understand what diameter the pump should be.

Some drilling organizations can install a 4-inch (100 mm) pump in a 117 mm plastic pipe. Her inner diameter 102 mm, so the narrowest 4-inch (98 mm) can be lowered there. But when it breaks, you won’t be able to get it back out, and the warranty on the well will end. Or the drilling organization itself will end.

Let's return to the choice, the well pump has a marking, for example Grundfos 2-70, in which the first number indicates productivity, and the second indicates pressure. Knowing these parameters, you can choose the right one submersible pump.

Performance well pump should be no more than 90-95% of the well's flow rate, and we will now calculate the pressure.

Choosing a pump for irrigation from a 10 meter well

So, suppose you have a summer garden and you need to lift water from a well 10 meters deep to water the beds. Such a shallow well was most likely drilled into sand, which means the flow rate is not high. Any cheap submersible pump will do. Here are some models chosen for performance.

Well flow rate is 1.5 m 3 /hour.
This is the optimal pump for this flow rate and depth:

• Aquarius 0.32-25U.
• Gilex Water Jet 40/50.
• Grundfos SQ 1-35 (3 inches)

Well flow rate is 2 m 3 /hour.
For a well with low productivity, these options are perfect:

• Aquarius 0.32-32U.
• Gilex Vodomet 40/75.
• SPERONI SQS 1-45 (3 inches)

Well flow rate is 2.5 m 3 /hour.
Here the best choice for such a 10 meter well with a small flow rate:

• Aquarius 0.5-40U.
• Gilex Water Jet 55/50.
• Grundfos SQ 2-35 or SQ 3-30 (3 inches)

Well flow rate is 3 m 3 /hour.
A sand well often does not have such a flow rate. Most likely this is a shallow artesian well:

Well flow rate is 3.5 m 3 /hour.

• Aquarius 1.2-25U.
• Gilex Vodomet 60/92.
• Grundfos SQ 2-70 (3 inches)
• UNIPUMP MINI ECO 2 (3 inches)

Well flow rate is 4 m 3 /hour.

• Aquarius 1.2-25U.
• Grundfos SQ 3-40 (3 inches)
• UNIPUMP MINI ECO 3 (3 inches)

You can choose the closest analogue from Chinese pumps. If you were drilled with a plastic casing pipe 117 mm or 110 mm, then you will have no other options except Chinese ones.
But you shouldn’t worry, a sand well lasts 5-7 years, and it makes no sense to use a really high-quality pump in it. However, if you really want quality, choose Grundfos or Speroni.

Water supply to the house from a 10 meter well

In the Moscow region (southern part), sand wells are not used to supply water to homes due to their drying out and other disadvantages, which we wrote about in detail in our article about sand wells. But if you do not have such problems or it is a very shallow artesian well, then let's choose a pump for it.
Let's look at water supply 2 storey building from a well 10 meters deep. To do this we need to calculate the pressure.

The water needs to be lifted from the well, this is about 10 meters, then the water needs to be raised to the tap on the second floor of the house, this is another 5 meters in height. In total, the water must overcome a height of 15 meters from the pump to the highest point of water intake. Accordingly, we need a head of 15 meters.
When you open the tap, you should get good water pressure, the usual pressure is 3 atmospheres. This is equal to another 30 meters of pressure, because 1 atm. = 10 meters of pressure. As a result, we have the required pressure of 45 meters. Let's set aside another 20 meters of pressure for losses due to horizontal movement of water and a small margin so that the pump works freely and quickly creates the necessary pressure for us.

In total, we need 65 meters of pressure for a 2-story house.

If 1-storey house, then just remove the extra 3 meters, because the pump does not need to raise water to the 2nd floor. The required head for a 1-story building will be 62 m.
These 3 meters are too small and they won’t make any difference to us.

Well flow rate is 2 m 3 /hour.

Well flow rate is 2.5 m 3 /hour.

For small artesian well The following pumps are perfect for low flow rates:

• Aquarius 0.5-80U.
• SPERONI STS 1014.
• Grundfos SQ 2-70. (3 inches)

Well flow rate is 3 m 3 /hour.

Our choice:

Well flow rate is 3.5 m 3 /hour.

• Aquarius 1.2-50U.
• SPERONI STS 1316.
• Grundfos SQ 3-65. (3 inches)

Well flow rate is 4 m 3 /hour.

• SPERONI SPS 1825.
• Grundfos SQ 3-80. (3 inches)

We deliberately did not take into account the dynamic water level. In such small wells, an error of +/- 5 meters is nothing; it easily fits into the pressure reserve.

What not to choose

There is no need to save every penny and buy a vibration pump. We have already talked about these pumps in

Today find submersible pumping equipment for the system autonomous water supply at the dacha or in a country house is not difficult: such devices are offered on the modern market in a wide variety of types and models. Having decided to purchase a submersible pump for a well or a well, many future users are wondering: which type of equipment will be able to most fully satisfy the requirements for it, ensure efficient and uninterrupted operation water supply systems, do not create any special problems with maintenance and repair. In order to pick up suitable model submersible pump for pumping water from a well, should be taken into account whole line factors, as well as understand the design, principle of operation, advantages and disadvantages of various types of pumping equipment.

Reasons for popularity

For servicing wells located on the territory personal plot, both submersible and surface water pumps can be used. Which pump is best to choose and install for pumping water from an underground source should be decided in a particular case, but quite often experts recommend paying attention to submersible type devices.

The high popularity of submersible pumps for wells is determined by a whole list of their advantages. So, in comparison with surface pumps, submersible pumps for wells have the following advantages.

1. Using a deep well pump, you can pump out water from even very deep underground sources and transport it through a pipeline system over a considerable distance. If you use surface water pumps, then you can use them to service only those wells whose depth does not exceed 8–9 meters. Naturally, the fairly low pressure of the liquid medium that is created household pumps surface type, does not allow them to transport water over significant distances and along a horizontal section of the pipeline.
2. During operation, submersible well pumps create a minimal amount of noise, which cannot be said about surface-type devices.
3. Deep well pumps for wells, they are more suitable for pumping contaminated water, which contains silt inclusions, fine sand and clay.
4. Since the cooling of submersible well pumps is ensured by the liquid medium they pump, it is quite difficult to overheat such equipment if the well has a good flow rate.
5. Submersible well pump, installed directly in the thickness of the pumped liquid medium, can be equipped with float switches that allow you to control the water level in the well, and also provide automatic switching on and shutting down equipment in cases where such levels reach critical values.
6. When installing and operating submersible well pumps, the tightness of the intake pipe is not subject to such high requirements as in the case of using surface equipment.
7. A well submersible pump is much easier to dismantle and place in a special storage place, which is especially important in cases where Vacation home or the dacha has to be left unattended for a long time.

When deciding which pump is best for a well, you should also study the disadvantages of submersible equipment.

• For connecting submersible well pumps to electrical network you need a high-quality and, accordingly, expensive cable with double insulation.
• When used for well maintenance submersible devices somewhat more difficult than when using surface pumping stations, coordinate the functioning of the automation elements that control the operation of all components of the water supply system.

Design, principle of operation, advantages and disadvantages

According to their design and operating principle, submersible pumps for wells and boreholes are divided into four types of devices:

• vibration pumps for wells and wells;
• screw hydraulic machines;
• centrifugal type devices;
• vortex type submersible pumping equipment.

To decide on the choice of a submersible pump for a well (which one is better), you should understand the design features, operating principle and scope of application of each type of such equipment.

Vibration pumps

A vibration pump for a well is the most a budget option equipment autonomous system water supply Distinctive feature vibrating hydraulic machines is simple in design, in which there are no rotating parts, which makes such equipment reliable and easy to operate, and facilitates its maintenance and repair.

The element that drives the vibrating water pump for a well is not an electric motor, but an inductance coil. Its core when passing an alternating electric current by turns of wire and creating magnetic field attracts and repels the device's anchor at certain intervals. The movement of the armature through the connecting rod is transmitted to the elastic membrane and the piston, which also begins to perform reciprocating movements (vibrations), which ensures the drawing of water pumped from the well into the working chamber of the equipment, as well as its subsequent pushing into the pressure line.

The body of the vibration pump, always made of metal, consists of two parts, the junction of which is sealed with sealing elements.

Among the advantages of vibration pumps, in addition to simplicity of design and fairly high reliability, we should highlight their low cost, as well as the ability to create a good pressure of the liquid medium in the pipeline system they serve.

For submersible hydraulic machines vibration type there are a number of disadvantages.

• These hydraulic machines do not have high productivity.
• When operating in the thickness of a liquid medium pumped from a well, such devices create vibration waves in it, which makes the water in the lower part of the underground source cloudy if its walls are not protected concrete rings. In addition, vibrations of the liquid medium contribute to the destruction of unprotected walls of wells.
• Pumps of this type not very suitable for dirty water, which contains inclusions of sand and small pebbles. The presence of contaminant inclusions in the pumped water prevents the tight fit of the equipment valves.
• If you decide to choose a vibration pump for your well, keep in mind that models of such equipment are not equipped with automatic elements, so you will have to purchase them additionally or monitor the operation of the device yourself.
• A vibration-type pump creates quite a lot of noise, although it is located in the thickness of the water layer.

The life of a vibration pump is often short-lived, but the simplicity of its design allows you to carry out repairs yourself

Vibrating type pumps, taking into account their specifications, advantages and disadvantages, are installed in repaired and cleaned wells and used in cases where high demands are not placed on the performance of pumping equipment. There are many different models of pumping equipment on the modern market, so the question of which vibration pump is better is quite relevant. Meanwhile, it should be borne in mind that most models practically do not differ from each other in technical characteristics, so you need to focus on the rating of the manufacturers of this equipment.

Screw pumps

To equip wells, screw-type submersible electric pumps are used very rarely, but, given functionality and the characteristics of such devices are worth considering.

The main design element of screw-type hydraulic machines is a screw, which is mounted on a shaft connected to the shaft of the drive electric motor. Rotating in the inner chamber of the pump, such a screw, with its protruding screw part, captures water entering the working chamber through the inlet and moves it to the pressure pipe.

Let's consider the advantages that distinguish screw pumps for wells and wells.

• The use of screw pumps allows you to create a good flow pressure of the pumped liquid medium in the pipeline system, the value of which is always stable.
• The noise level created during operation of such a pump is minimal.
• Screw pumps are best equipment for dirty water, which may contain even fairly large grains of sand. What is noteworthy is that screw pumps were specially designed to work with viscous media and dirty water.

The reasons for the rather limited use of screw-type submersible hydraulic machines are that such devices are characterized by a number of significant disadvantages:

• low productivity;
• the lowest efficiency among submersible pumps, which is explained by the presence in the design of such devices of a large number of rubbing elements;
• intense wear of parts due to a large number of friction units, which leads to frequent repairs.

Due to the above disadvantages, screw pumps have the lowest rating among submersible household pumping equipment.

Centrifugal pumps

The most popular type of pumping equipment used for autonomous water supply systems for private houses and cottages is a centrifugal pump for a well or borehole.
The main working element of such equipment is a wheel, on outer surface which fixed curved blades. When the impeller rotates inside the working chamber, the blades capture the liquid located there and begin to move with it. Thus, centrifugal force begins to act, which throws the liquid towards the walls of the working chamber, where it is created overpressure, ensuring the pushing of the liquid medium into the pressure line. When these processes occur, a vacuum of air is created in the central part of the chamber, which ensures the suction of a new portion of the liquid medium through the inlet pipe.

Centrifugal devices are among the best submersible pumps for wells. This is related to the following.

1. Working according to the above principle, centrifugal pumps are capable of forming a flow of liquid with powerful pressure, which allows them to be used for pumping water even from very deep underground sources and transporting it through a pipeline system over considerable distances.
2. Such pumps also have impressive performance.
3. During operation, centrifugal hydraulic machines create a minimal amount of noise.
4. A wide variety of models of centrifugal pumping equipment offered on the modern market makes it possible to select a pump of this type that will optimally meet the required parameters.

Among the disadvantages of centrifugal pumps, the following should be noted:

• complexity of the design and, accordingly, maintenance and repair;
• quite high cost;
• significant reduction in service life when used for pumping contaminated liquid media.

Vortex pumps

Vortex-type submersible pumps operate on a principle similar to centrifugal devices, but differ from them in a simpler design. Such devices also have an impeller with blades of a special configuration, and special grooves are made on the inner walls of their working chamber. This design allows not only to influence the pumped liquid with centrifugal force, but also to impart turbulent acceleration to its flow. Thus, vortex-type pumping equipment creates a fluid flow with even more powerful pressure and pumps it with even greater productivity than centrifugal devices.

Other advantages of vortex-type submersible pumps include:

• lower price than for centrifugal devices;
• enough simple design, facilitating them Maintenance and repairs;
• almost complete absence of noise and vibration during operation;
• the ability to effectively pump liquid media that contain a certain amount of air or any other gas, which allows the use of such equipment not only for domestic, but also for technological purposes.

The disadvantages of vortex-type equipment, which do not allow us to call it the best pump for a well, include:

• inability to work with liquid media that contain even a small amount of solid inclusions;
• not too long, when compared with centrifugal-type devices, service life.

In order not to constantly encounter problems in the functioning of the autonomous water supply system that arose due to malfunctions in the operation of pumping equipment, you should know how to choose the right submersible pump for a well. The pump you choose will operate efficiently and will not require frequent maintenance or repair if you answer the questions below before purchasing it.

• What problems will the water supply system need to solve for which a well pump is purchased? Such tasks, in particular, may be the use of water for economic needs and work household appliances, watering the garden, washing the car, etc.
• How deep will the pump go into the well to pump out water? You should also take into account the thickness of the water layer in the well and its flow rate, so as not to constantly encounter the problem of incorrect operation of the pump, which has taken all the water from the underground source.
• What is the degree of contamination of the water at the source? Knowing this information will help you accurately determine which submersible pump would be better suited for a well.

After answers to all of the above questions have been received, we can say that the problem of a submersible pump for a well (which one to choose from a number of models) has been solved.

The choice of pump for a well is carried out according to such parameters as:

1. the flow pressure of a liquid medium that a pump can create to ensure its lifting from a certain depth of an underground source and transportation through a pipeline to all water intake points;
2. productivity, indicating how much water per unit time the pump can supply to the water supply system;
3. the degree of water contamination with which the selected device is capable of working;
4. material of manufacture of the pump body and its internal elements (these characteristics affect the durability of the device, as well as the quality parameters of the water that it will supply to pipeline system);
5. Availability additional options, automation and protection elements;
6. drive motor power;
7. electrical parameters, dimensions and weight;
8. trademark, under which the pump is manufactured, as well as the warranties provided by the manufacturer.

Having decided which submersible pump suits you best in terms of basic parameters, choose a model with some margin in pressure and performance. This is explained by the fact that any of the elements of the water supply system creates hydraulic resistance, which is quite difficult to take into account when performing preliminary calculations. That is why, choosing a pump whose technical characteristics slightly exceed the calculated parameter values plumbing system, you definitely won’t encounter the problem of its ineffective operation.

Following the recommendations described above, you can decide on how to choose a pump for a well yourself. However, when choosing a submersible pump, it is worth consulting with a specialist from the selling organization, from whom it is advisable to obtain information about what service centers your region provides maintenance and repair of the equipment you choose.

When solving the problem of water supply using a well, you need not only to build it correctly. It is also necessary to choose a suitable pump for it.

Our article will tell you how to choose pumps for wells.

Criteria for choosing a pump for a well

To figure out how to choose well pumps correctly, you must first decide on the selection criteria.

They will be as follows:

1. Purposes and frequency of use - if you plan to use the pump for some narrow purposes and do it irregularly, then you should not buy an expensive model. For example, for watering a small plot of land, an inexpensive device “Rucheyok” or “Malysh” will be quite sufficient. And to provide year-round water to all residents of the house, it is worth looking at more powerful models;
2. Performance - when solving the problem of how to choose a pump for a well, you need to determine the volume of water required to meet your needs. In this case, you should take into account all points of water intake - these are all taps, toilets, washing and dishwashers. For the calculation, the amount of water that can be consumed at a time is taken;
3. Water pressure is another parameter that cannot be ignored when talking about how to choose a well pump. This criterion indicates the maximum height to which the device can deliver water. You should choose those devices in which this value is slightly higher than the value that you require. This is due to the need to overcome pipe resistance;
4. Type of equipment - all types of devices have certain design features that must be taken into account when giving preference to one type or another.

Advice!
Pay close attention to the performance of the product.
If the device turns out to be less powerful than required, this will lead to various problems during its operation.
In particular, the set of water in large containers will take much longer than you would like.

Types of well pumps

All these devices can be divided into surface and submersible according to the type of placement. By design features They are divided into centrifugal and vibration. Let's take a closer look at these types.

Surface type

These units are installed at some distance from the water source, which makes them quite popular among owners country houses. After all, such devices can be installed directly in the house, and this greatly simplifies their maintenance.

Thinking about how to choose pumps for a well, Russian buyers often choose brands such as CALPEDA (Italy), WILO (Germany), GRUNDFO (Denmark). Russian products are also in demand, for example, products from the company “Dzhileks”.

It should be noted that such devices are capable of lifting water from a depth of no more than 9 meters. This is their disadvantage, because of which summer residents may prefer another type of device - submersible.

Submersible type

Such devices are placed in a well, directly in the water column. During operation, they are cooled by the flow of water passing through them. Because of this, you cannot turn on such a pump without water, as it may fail.

Except this deficiency, submersible machines also have a number of advantages:

• reliability of design;
• simplicity of the device;
• the ability to supply water from great depths.

Among such devices are separate subspecies- These are well devices. They are characterized by more efficient cooling and tolerance to the presence of solid impurities in the water.

When thinking about how to choose submersible pumps for wells, we recommend taking a closer look at products from the WILO, LOWARA and NOCCHI brands. They perform well during operation, distinguished by their quality and reliability.

Centrifugal type

Devices of this type are equipped with a wheel with blades placed inside the body. It is rotated by an electric drive, which creates a centrifugal force that pushes water into the pipeline.

The disadvantage of such a pump is its extreme demands on water quality. The presence of even small impurities in it will inevitably lead to failure of the device. As for the advantages, these include high performance and ease of operation.

Vibration type

The devices related to it are characterized by the absence of an electric motor. Its function is performed by electric and vibration magnets.

Thanks to its simple design, this device is very reliable and can last for a very long time. Another advantage is its low price. This is why vibration pumps have become so widespread.

Optimal technical parameters of well pumps

Now it’s time to consider how to choose a submersible pump for a well or another type of device with optimal technical parameters.

Power

This parameter is measured in watts (Watt) or kilowatts (kW). It is an indicator of the volume of water pumped per unit of time. The more points of consumption, the greater the power should be.

Advice!
It is not worth purchasing a unit with maximum power, as this will lead to unnecessary waste of money.
For the needs of a small family, a device with a power of 250-350 W will be sufficient.

Performance

This is the amount of water that a well pump can lift in a certain time. The unit of measurement in this case is cubic meter per hour (m³/h). For a family of three, a device with this figure of 4.2 m³/h will be quite sufficient.

Maximum head

For good water supply from the well, sufficient pressure in the pipes is necessary. It's called pressure.

The following instructions will help determine its optimal value:

1. to the depth of the well we add the horizontal distance, that is, the length of the ground hose or pipe;
2. for every 10 meters of the resulting gap we add 1 meter - this is the pressure loss during transportation;
3. We add another 20% to the resulting figure - this will be the final result.

Conclusion

Having made a well with your own hands, you need to select and install a suitable pump in it. For selection the required device First of all, you need to decide specific goals and the expected frequency of its use. This will help you choose the type of pump, as well as its specific model with optimal technical parameters.
