Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation in intermittent operation.

Hydraulic part

Horizontal pressure connection for flange connection Maximum possible dry matter content is 8 % (depending on the type of hydraulic part). Free-flow impellers are used in the design.

Electric motor

Surface-cooled, single-phase (with built-in operation capacitor) and three-phase direct-start electric motors are available. Heat is dissipated directly to the environment via the motor housing. The motors can be operated in immersed state in continuous duty (S1), and in non-immersed state in intermittent duty (S2) or intermittent duty (S3).

In addition, the electric motors are equipped with sensors for monitoring the temperature of the motor winding. They protect the motor winding from overheating. On units with single-phase motors, they are integrated in the electrical circuit and operate automatically without external device. That is, the electric motor is switched off when overheated and is automatically switched on again after cooling down. According to the standard, bimetal sensors are used for this purpose.

In addition, the electric motor can be equipped with an external seal chamber tightness monitoring electrode to monitor the oil chamber. This indicates the ingress of water into the oil chamber through the mechanical seal on the fluid side.

The standard length of the power cable is 10 m and it is available in the following versions:

  • With loose cable ends
  • With plug
  • With float switch and plug


There is a sealing chamber between the electric motor and the hydraulic part. It is filled with white medical Vaseline oil. The fluid-side and motor-side seals are provided by two mechanical seals which rotate independently of each other.
