Description/design

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.

Materials

  • Motor housing: aluminium or EN-GJL 250 (depending on type and version)
  • Pump housing: EN-GJL 250
  • Impeller: EN-GJL 250
  • Shaft: 1.4021
  • Sealing on motor side: mechanical seal in various material versions
  • Sealing on pump side: Mechanical seal SiC/SiC
  • Static gaskets: FPM

Scope of delivery

Pump ready for connection with 10 m connecting cable (starting from KS 24, 20 m) and single-phase or three-phase current plug, Storz or GEKA solid coupling, 90° bend if necessary for implementation of vertical pressure outlet, installation and operating instructions.
