Construction

DrainLift WS 40E Basic (1~230 V)

Chamber

Pump chamber with optimised geometry for deposit-free operation. Chamber component with finning for high inherent stability and anti-buoyancy. The inlets are freely configurable. Two lifting eyes are integrated for attaching the lifting accessory. The upward curved pump chamber cover can be walked on and can be loaded with max. 200 kg. For the building installation, the pump chamber is equipped with a floor fixation.

Pipework

  • Discharge pipe with threaded connection on the pump side
  • Shut-off ball valve
  • Non-return ball valve

Pump

Submersible sewage pump for single-phase current. Surface-cooled motor with thermal motor protection (self-switching) and plug.

Level control

The level is controlled via the float switch of the pump.
