A cable is inserted into the safety loop. The entire structure is lowered into the water. The pipe coming from the pump is connected by a coupling to the water supply, the cable is plugged into a socket, and the cable is attached to the brackets of the upper concrete ring in the well. Lowering the device while holding the cable is prohibited!

A huge selection of pumping units, differing from each other not only in performance characteristics, but also in design and principle of operation, can put you in a difficult situation. Which pump to choose for a well and how to ensure it works flawlessly, economically and meets all the requirements? It won’t be difficult to answer this question if you understand all the nuances, consider not only characteristics various categories of equipment, but also auxiliary equipment, automation. It is equally important to identify the most reliable equipment manufacturers.

All pumps that can be used to supply water from a well can be classified according to the operating principle:

• screw,
• centrifugal,
• vortex,
• vibration.

Depending on the installation method and location pumping units can be:

• superficial,
• submersible

Comparison of surface and submersible models

From the name of these categories it is clear that some are installed on the surface, taking water from the source using special pipe or a hose immersed in a well, the latter work in the water column. However, the installation location is not the only difference; models of these types, with equal power, will have different capabilities and technical characteristics. When comparing pumps for wells, how to choose a unit can be understood by the operational capabilities of the models.

Surface Models

Surface pumps are most often installed next to the well, but in some cases they can operate “float”, for example, on a raft made of foam plastic or other buoyant and moisture-resistant material. In the second case, it is important to calculate the capabilities of the floating support and relate them to the mass of the unit.

When choosing a surface pump, special attention should be paid to the lifting height, this parameter differs different models, but usually does not exceed 8 meters. For greater depth, it is recommended to choose submersible models, but in cases where the excess depth of the well is not large, you can use a surface pump with an ejector. A fairly simple device, the operating principle of which is based on the formation of vacuum when the speed of water flow increases, increases the ability of the unit to lift liquid from great depths.

Main advantage surface pumps– simplicity Maintenance and repair, accessibility for visual inspection.

Disadvantages, in addition to restrictions on the height of water rise, one can consider a higher noise level and vulnerability to external factors compared to submersible models.

If the surface unit is used seasonally, it can be protected from precipitation using a canopy. If you use the equipment year-round, you will need to install it in a heated, insulated room or in to avoid freezing.

Submersible units

A deep pump for a well is usually used when the water is below a level of 8 meters and, as a rule, is installed in such a way that about 50-100 cm remains from its lower part to the bottom. If the bottom is closer, the risk of capturing bottom sediment will increase. The quality of the supplied water will decrease, and the likelihood of breakdown of the pumping unit, designed to work with clean water, will increase.

Which submersible pump to choose for a well is determined, among other things, by its lifting characteristics, which are higher for this type of unit compared to analogues.

In addition, such models are recommended for installation in cases where the well is located close to the house or recreation area on outdoors. The mass of water above the unit absorbs sound waves, so the noise level when operating such models is noticeably lower. When choosing submersible pumps for wells, which one is better is determined by whether the unit meets the requirements of performance and pressure.

The disadvantage of submersible pumps is the difficulty of maintenance. Even in order to inspect and check the unit, it is necessary to stop its operation and remove the equipment from the well using a cable.

Centrifugal and vibration models

Taking into account the operating characteristics of various models, it is easier to choose the optimal pump for specific conditions.

Vibration pumps

A vibration water pump for a well differs from all other designs in the absence of rotating elements. This nuance can significantly increase the wear resistance of the equipment.

Instead of a classic motor, vibration pumps use an electromagnetic coil that attracts a rod with a piston when current is applied. At this time, a vacuum is created in the pump chamber, and water is sucked inside. Next moment operation - disappearance of current, stop of the rod stroke. To prevent water from flowing back, a check valve is activated, so under the pressure of the piston, the liquid moves into the space behind the piston. During the next oscillation, the appearance of current and the movement of the piston will ensure not only the suction of liquid, but also the pushing of water from the space behind the piston into the supply pipeline.

Such reciprocating movements of the rod can be considered vibrations, which is why the pump got its name.

Installation of vibrating models is generally safe for the well. The exception is springs on quicksand. Due to the low density and strength of the soil, vibration can cause deformations in the soil layers and, as a result, destruction of the well structure.

Reliable vibration pumps are also characterized by low cost, which makes this option very attractive for equipping a water supply system, if in other respects the selected model is also suitable for specific conditions.

Centrifugal pumps

The principle of operation of centrifugal pumps for wells for water supply is based on the formation of a centrifugal force during rotation of the working element, under the influence of which water passes from the filled chamber into the pipeline, forming a vacuum zone into which the next portion of liquid is sucked. The direction of water movement is determined by the pressure in different sectors of the pump: reduced at the center of the rotating wheel, increased at the walls.

Structurally, the working element is a wheel mounted on a shaft with blades placed on it. The bending of the blades is against the wheel travel.

The operation of a centrifugal pump has its own characteristics. The unit can only be turned on when it is completely submerged in water. This allows you to avoid “dry running”, which is dangerous for the equipment, and protect the model from damage during a power surge. When operating a centrifugal model, it is important to control the water level, so a submersible well pump with automatic equipment comes complete with a simple float, which will eliminate the possibility of air entrapment when the level decreases.

Centrifugal pumps will be the optimal answer to the question of which pump is best for a well in which the water contains small insoluble impurities (sand). The content of impurities in water can reach 185 g/m3. To protect against the abrasive action of sand, it is better to choose models with bodies made of of stainless steel. If the water is clean and the operating mode of the unit is not excessively intense, you can choose cheaper models with plastic bodies.

Advice: If there is a large number of impurities and sand, you should pay attention to a vibration pump, which is more resistant to contamination, of course, if its performance suits you.

Criteria for selecting well pumps

Which pump to choose for water supply from a well is determined by technical specifications models. They must meet the requirements, so before purchasing it is important to determine the required values ​​of the main parameters.

Power

The amount of power determines the ability of the unit to create a certain pressure and affects the performance of the equipment. However, one should not assume that for efficient work system, it is enough to select the most powerful unit. Power that far exceeds the required value can cause excess pressure in the pipeline, squeezing out gaskets, and causing ruptures. In addition, a powerful pump for a well in a country house will quickly pump out the volume of water available in the shaft, and this will lead to frequent switching on and off, and rapid wear of the unit.

Performance

Productivity is the volume of water that a well pump for water supply to a home is capable of pumping over a certain period of time. Correct selection of this characteristic will ensure uninterrupted water supply even during peak loads. To calculate, it is necessary to sum up the fluid flow at all water intake points in the house.

If the exact value of the parameters is not known, you can use the following guidelines:

• washbasin – 300 l/hour,
• shower – 700 l/hour,
• toilet - 83 l/hour.

If a bathhouse and an irrigation system are connected to the water supply system, it is necessary to add 1000 l/hour for each of these objects.

Of course, the likelihood that all water consumption points will operate simultaneously is not great. Such calculations do not determine the nominal, maximum maximum value of water consumption.

A submersible pump for a well with automation that does not have the required performance means not only interruptions in the water supply to the house, but also an increase in the likelihood of accidents when operating equipment sensitive to water supply.

Pressure

The pressure characteristics of the pump determine its ability to lift water to a certain height from the depth of the well and transport the liquid along horizontal lines to points of water consumption. When summing up the lifting and pumping pressure, every 10 meters of horizontal distance is equivalent to 1 meter of lifting.

For example, if the well is 7 meters deep and its distance from the house is 20 meters design head calculated as follows: 7+20/10=9 meters. If the house has more than one floor and it is planned to install water intake points above the first floor, this should also be taken into account in the calculations. For the example under consideration, when installing a water supply system on the 2nd floor, the pressure value will be equal to 7+20/10+4 =13 meters, where 4 is the approximate height of the second floor of the building.

Important: When carrying out such a calculation, it is always necessary to select the unit pressure value with a reserve, since there are certain losses in the pipeline, which depend on the specific water supply scheme.

One of the popular representatives of vibration units is. Its main advantages are fairly high reliability at a minimal price.

If the depth of the water source is shallow, you can use ready-made surface pumps.

And if you want to learn about using plastic pipes, then we have a separate article on this topic.

Extra options

When choosing a model, additional parameters are important that will help make the necessary calculations.

Static levels

Static levels are the depth of the shaft and the level of the water surface when the well is filled. Both quantities are easily measured using a string with a weight: the depth of the well - until the weight reaches the bottom, the level of the mirror - until a characteristic splash occurs when the weight enters the water.

Dynamic level

The dynamic water level in the well indicates the intensity of liquid inflow into the shaft. This value is also called the debit of the source. The dynamic level can be determined by pumping water from the mine. When, despite the operation of the pump, the water stops decreasing, the dynamic level of the well has been reached. In sources with a high dynamic level, the position of the water surface changes slightly during pumping.

Shaft diameter

The diameter (or side length with a square section) of the shaft is necessary to calculate the volume.

Optional equipment

Additional equipment helps ensure pump safety and water supply efficiency.

• Floats and level sensors protect against air suction, dry running and the formation of air pockets.
• Uninterrupted supply and economical operation depend on the presence or storage tank.
• Hydraulic accumulators are equipped with controls that control the parameters for turning on and off the pumping unit.

Popular manufacturers

Which pump to buy for a well should be decided individually, but it is preferable to choose it from among models of well-known brands.

• Gardena(Gardena) – efficient and low-noise German pumps with double gaskets and reliable engine protection. Built-in check valves optimize the operation of the unit.
• Baby- a series of several models of vibration pumps, characterized by simple design and low cost (for such a submersible pump for a well, the price will be only 2000 rubles). Should not be used for continuous operation. Pressure – 40 m, productivity depending on the model 432-1000 l/hour.
• – an economical centrifugal submersible pump for domestic purposes from a Kharkov manufacturer. Suitable for pumping drinking water.

If the distance from the wall of the tank (well) to the pump is less than 1.5 meters, a model with a mesh filter is recommended.

A surface pump is located next to the well or in the house, and a submersible pump is lowered into the well. In well models, the suction hole is located at the bottom, so the pump works even if it is not completely submerged in water. A float switch that is activated when the water level drops prevents dry running. It is recommended to maintain a distance of one meter from the pump to the bottom of the well, no less. This prevents the pump from sucking up silt and sand from the bottom.

Pumps differ in their mode of operation:

1. Centrifugal - with an impeller screw; when rotating, the screw creates an area low blood pressure, and water is absorbed.
2. Vibrating - water is pumped by a piston, which is a moving part of an electromagnet.

Pump models differ in pressure, functionality, and performance.

Pumps for ten-meter wells: make the right choice

The height of water lifting for centrifugal and vibration pumps is up to 60-70 meters. The vibration-type range includes pumps with a capacity of up to 1000 liters per hour, while centrifugal pumps can operate ten times more efficiently.

Advantages of Vibration Pump – simple design and energy efficiency. With the same power, the productivity of the vibration model is higher than that of the centrifugal model.

Disadvantage: vibration causes the ground to move. The sandy bottom rises when such a pump operates for a long time. Buildings may suffer from ground vibrations.

Pumps for ten-meter wells: price depends on design

Vibration pumps are cheaper than centrifugal pumps, with equal power. For occasional use, not too long, buyers choose a vibration pump. If you need to pump water constantly, then use a centrifugal one, although it is more expensive.

Characteristics of pumps for ten-meter wells

Water must be raised to the surface and delivered to the place of consumption. Therefore, pumps for ten-meter wells are chosen with a reserve in the height of water rise.

Models of vibration pumps designed to lift water to a height of more than 10 meters are few in number. Buyers prefer centrifugal well pumps to supply water from a ten-meter well.
type.

The power of vibration pumps is 250-300 W, and centrifugal pumps

develop a power of 0.5-2 kW.
The productivity of a 300 W vibration pump will be 16 l/min, and the productivity of a 1.1 kW centrifugal pump will be 150 l/min.

Purchasing a pump for maintenance country house will save you from a lot of problems. Relatively inexpensive compact equipment will collect water in containers for irrigation and deliver it to the bathhouse, kitchen, or pond or pool equipped on the site. Agree, doing so many things manually is too difficult, and almost impossible.

Pumping equipment will easily perform all the work listed for you if all technical and hydrogeological nuances were taken into account before purchasing it. We are happy to help you understand this difficult issue. The article presented for review contains all the characteristics and circumstances necessary for making an informed choice.

The information we offer will help you thoroughly understand what you should pay attention to before purchasing, which pump is best for a well, and what needs to be provided for connection. We have listed the leaders in the production of pumping equipment for private purposes. The information is supported by video and photo examples.

Before purchasing a well pump, you need to carefully prepare.

Without information about the source of water supply, even a brilliant salesman will not be able to accurately say which device is ideal.

The characteristics of the pump are selected based on the calculated water flow rate and the type of source from which water is to be extracted

For perfect pump selection, the following information is required:

• Distance from the entry point to the bottom of the well. For country prefabricated water supply systems, it is counted from the top edge of the head, because the water supply hose is usually routed through it. For permanent water pipelines, the specified distance is set aside from the entry point through the wall of the well. It can be determined with the simplest measuring device made of string and a weight tied to it.
• Static level or otherwise a mirror of water. This is the distance from the ground line to the surface of the water in the well. To determine it yourself, the above-described device must be upgraded by replacing an arbitrary weight with a heavy nut. You need to tie it to two opposite walls so that the hole in the nut that comes into contact with the surface of the water makes something similar to a pop.
• Dynamic level. It is determined in a similar way, but before it is measured, water is pumped out from the excavation. Before determining the static indicator, water cannot be pumped out.
• Full height of the well. This value can be found by adding the heights of the rings used in the construction.
• Site plan with dimensions. It is necessary to determine the distances from the water intake site to the water collection points. A hand-drawn diagram with precisely marked distances will do.
• Difference between dynamic and static level characteristic. The value gives the right to determine the flow rate of the well.
• The height of the water column. Equal to the distance between the bottom and the dynamic level.
• Degree of water pollution. Whether it is crystal clear or with a fine suspension, it belongs to the technical or drinking category.

Armed with measured and calculated data, you can safely go to a specialized store.
