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.

Typical applications:
