Types of pumps for wells
The surface ones are not submerged in water, but are installed side by side – on the ground or on a floating platform. Used if the lifting depth does not exceed 9-10 m. They only work at above-zero temperatures. They must be protected from water ingress, otherwise the engine may burn out.

The submerged ones are partially or completely lowered into the well. They pump water from a considerable depth. They are suitable for creating an Autonomous water supply system. According to the principle of operation, they can be vibrating and centrifugal.

Vibration-the most budget. They work due to a flexible rubber membrane. They create reciprocating movements, which is why they lift sand and other debris from the bottom. Their service life is short – abrasive particles often get inside and damage the mechanisms.
Centrifugal (borehole) pumps are suitable for long-term operation. They are characterized by high performance and pressure. The housings are narrow and elongated, fit even in small (from 80 mm) wells. Some models can lift water from a depth of up to 100 meters – they are suitable for artesian wells.
The screw ones work by means of a screw screw. When it rotates, water rises from the well, and then under pressure falls into the hose. These pumps are suitable for domestic systems of Autonomous water supply. Narrow housings can be installed in boreholes from 90-100 mm.
The vortex creates a pressure through the impeller (the impeller). They suck the liquid from the inside of the channel and pump it into the outside, which causes a longitudinal vortex to appear. Suitable only for clean water from wells (from 100 mm), reservoirs and open reservoirs. They create 3-7 times more pressure than conventional centrifugal pumps.
