Submersible drainage pump as submersible monobloc unit for portable wet well installation.


The outlet on the pressure side is designed as vertical threaded connection with Storz coupling. Open channel impellers are the impeller type used.


Up to size 20, single-phase or three-phase current version self-cooling motors are used. The self-cooling motors are oil filled. From size 24, three-phase current version surface-cooled motors with thermal motor monitoring and sheath flow cooling are used.

The Ex-rated units KS ... Ex units are equipped with a surface-cooled motor without sheath flow cooling.

All models can be used both immersed and non-immersed, in continuous duty. This also permits slurping operation.

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

Up to size 20, the connection cable is detachable and the cable is 10 m long. From size 24, the connection cable is permanently connected and the cable is 20 m long. The connection cable is always equipped with a plug. The S version is also equipped with a float switch. The DMS version is equipped with a switchgear which has integrated motor protection.


The sealing on the fluid side and on the motor side is performed by two bidirectional mechanical seals.
