Submersible pumps are of 2 types:
According to the principle of operation, submersible pumps are divided into vibration and centrifugal
Submersible vibration pumps are ones of the simplest electric pumps in design. Their operation is based on changing air and water pressure in the inner chamber by way of reciprocating movements of pump piston. These pumps have no rotating parts and no drive motor, so they are easy to maintain and repair.
Centrifugal electric pump for boreholes is a pump inside of which centrifugal force is created, which pushes water upward. It is suitable for deeper submergence and water supply from boreholes several tens of meters deep. In addition, most of them have a forced cooling system.
