How to choose submersible pumps for wells: selection criteria

AT country houses, the water supply system often depends on a well or well, which is equipped at a depth of 8-10 meters. It is not possible to get water from such a depth on your own. Moreover, it is inconvenient every time you need fresh drinking water to go outside. Therefore, owners of summer cottages and suburban housing should pay special attention to models of submersible devices. They will ensure uninterrupted water supply to the home. Let's look at how to choose submersible pumps for wells and the principle of operation of the mechanism.

What does a submersible pump look like?

The submersible pump works in water. It lifts liquid even from very deep wells and wells to the surface. It is worth distinguishing between well and downhole devices. Downhole, as a rule, have a more oblong shape for working in narrow wells and a higher head for lifting water from great depths.

These species have minor differences in the device. Basically, all units consist of the following parts:

• The impeller, which is the main structural element. It sets in motion all the other details of the structure;

Instrument impeller

• Wheel blades. They develop centrifugal force, which is necessary for the rapid absorption of water;
• Suction area;
• Impeller housing. It protects him from the negative influence of the environment;
• Valve - retain water in the pump and prevent its return to the well;
• Protective mesh - necessary to protect drinking water from harmful impurities that can adversely affect the health of residents of the house.

A submersible blower is powered by electricity. It causes the impeller to rotate. Thus, the liquid flows from the well or well into the pipeline, which, in turn, conducts water to the plumbing system.

As we can see, the principle of operation, as well as the design of the supercharger itself, are elementary. And now let's find out what types of these devices exist and how to choose a submersible pump for a well.

Submersible unit classification

According to the design, the following types are distinguished:

• vibratory- is a design of a vibrator, an electromagnet and a housing. It is widely used in suburban areas, not only for pumping and delivering water to the house, but also for the garden. Vibrating devices show good performance in terms of pressure and power. At the same time, their price is low;

• Vortex- consists of a discharge area and an electric motor. The first element is used to pump liquid, the second - to supply water to the house. This type is able to lift water from a depth of 12 meters. In this case, the process occurs quite quickly;

• Centrifugal- a complex of two blocks: a working chamber and an engine. They pump out up to several hundred liters per hour due to the presence of a special centrifugal shaft. However, such devices have one significant drawback: they consume too much.

Submersible Device Selection Criteria

To make the device suitable for your home, you should decide on the following parameters:

• The distance from the well to the dwelling. The greater the distance, the more powerful the pump model should be chosen;
• The volume of water consumed. As practice shows, for ordinary families consisting of 4-5 people, the most common medium-power blower is suitable. But if more people live in the house, it is worth choosing a stronger model;
• Performance. This parameter is measured in liters of fluid that the pump can lift per unit of time. On average, productivity reaches 4.2÷4.5 cubic meters. However, if the device is necessary not only for the usual water supply of the dwelling, but also for irrigating a spacious personal plot, then you should pay attention to models with a capacity of 4.8 cubic meters and above;
• Power. Denoted in kilowatts. This indicator indicates the volume of water supplied per unit of time. But you should not buy a device on the principle of "the more power, the better." If your family does not need too much water, then take a blower with a medium power, as a device that is too powerful consumes a lot of energy.

Focusing on these indicators, you will choose the best unit for your home, which will serve you for many years in a row.
