Submersible Pumps

Pump Service and Technology UK

Submersible Pumps are one of the main components of Package Pump Stations, as well as being used in isolation for many different applications.

Submersible pumps come in many different shapes and sizes, and thus can be used for a multitude of different applications, ranging from small scale drainage and dewatering to dam and reservoir management.

The principle of all submersible pumps, however large or small, is always the same; the pump comprises two main areas. The Volute (of Hydraulic End), and the Motor Housing.

The Volute is a chamber which is flooded, and contains an impeller which displaces the water around the volute, which then exits via the discharge port by centrifugal force.

The Motor Housing is a sealed chamber in which the motor runs under dry conditions. The motor housing is kept watertight by mechanical seals where the motor shaft passes through to drive the impeller (many submersible pumps use dual mechanical seals). The power cable enters the motor housing via a specially designed entry seal, which is integral to the power cable to prevent water ingress between cable and seal. This entry seal is then bolted to the pump casing with 'o' ring(s) to ensure complete water tightness to IP68.
