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


The outlet on the pressure side is designed as vertical threaded connection Rp 1½. Vortex impeller are used as the impeller shapes.


The oil-filled motors give off heat directly to the pumped fluid via an integrated heat exchanger. As a result, these motors can be used in immersed state for permanent and intermittent operation. In non-immersed state, these motors can be used for intermittent operation.

A sealing chamber protects the motor from fluid ingress. The filling fluid used is potentially biodegradable and environmentally safe.

The motor cable and float switch can be detached and replaced.


Sealing on the fluid side is achieved by a bidirectional mechanical seal, while sealing on the motor side is achieved by a rotary shaft seal.
