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


The outlet on the pressure side is designed as a vertical threaded connection Rp 1½ with an integrated non-return valve. Semi-open channel impellers are the impeller type used.


Single-phase or three-phase current version surface-cooled motors with thermal motor monitoring. In the single-phase version, motor monitoring switches automatically. The waste heat is given off directly to the surrounding fluid via the housing components. As a result, these units must always be immersed for permanent or intermittent operation.

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

The detachable connection cable has a length of 10 metres and has bare cable ends. A version is equipped with a float switch and plug.


Fluid-side and motor-side sealing is performed by bidirectional mechanical seals.
