Submersible pumps

Submersible and borehole pumps (deepwater pumps) are used to supply liquid from reservoirs, wells, reservoirs and wells by direct immersion and provide liquid lifting from depths not accessible to other centrifugal pumps.

Features of submersible pumps

In comparison with downhole pumps, submersible pumps are less sensitive to solid particles contained in water and are widely used in water supply systems. The pumps are equipped with float switches. By cooling the engine with pumped water, submersible pumps have better cooling compared to downhole pumps.

The submersible pump is installed below the level of the pumped liquid and provides lifting of the liquid from a great depth. It can be installed in mine wells, process tanks. There are two types of submersible pumps: rod submersible pumps and rodless submersible pumps.

Rod - in which the drive is carried out from an independent motor located on the surface of the liquid through a mechanical connection, and rodless - are performed in one unit with an electric (or hydraulic) motor. The electric motor is powered via a submersible power cable. This type also includes a borehole pump, a well pump, as well as a fecal pump and a drainage pump.

The fields of application of submersible pumps are water supply and sewerage, irrigation systems, utilization of low-potential geothermal energy by heat pumps.
