Submersible pumps are used for supply of water for drinking, irrigation, and various industries and applications.
The principle of a submersible pump is a unit combining a pump body and a motor to an enclosed unit, suitable for submerged installation in a fluid.
Two types of submersible pumps:
- With a submerged motor
- With a dry motor, which is connected to the pump by a long shaft
Submersible pump facts
The submersible pumps come as both:
- Single-stage pump
- Multi-stage pump
The multistage version is the most common type.
The pump may be connected to a riser pipes with a non-return valve, or can be connected with a flexible hose. The pumps are designed to be submerged in a liquid and are most often fitted with a submersible hermetically sealed motor. Motor and pump are connected with a coupling, from the pump shaft to the motor shaft. Power to the motor is fed through one or more flexible watertight cable.
