Description/construction

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

Hydraulics

The outlet on the pressure side is designed as a horizontal or vertical threaded connection. On models with a horizontal pressure connection, a 90° elbow is attached to make a vertical outlet possible. Open channel impellers with free ball passage of 5…45 mm are used as the impellers.

Motor

Surface-cooling or self-cooling motors in single or three-phase versions are used, depending on the type. The self-cooling motors are filled with oil; the surface-cooling motors have thermal motor monitoring and sheath current cooling. The Ex-rated units KS 5, KS 6 and KS 16 are equipped with a surface-cooled motor without sheath current 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.

The cable is detachable, the cable length is 10 m or 20 m. The S version is equipped with float switches. All models are equipped with plugs. The DMS versions are equipped with a switchgear with integrated motor protection.

Seal

Sealing on the fluid side and on the motor side is achieved by a bidirectional mechanical seal.
