Description/construction
Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation.
Hydraulics
The outlet on the pressure side is designed as DN 50 or DN 65 horizontal flange connections. The impeller shapes used are single-channel (E) or vortex impellers (F).
Motor
Surface-cooled motors give off their heat directly to the surrounding fluid via the housing components and can be used in immersed state for permanent or intermittent periodic duty.
A sealing chamber protects the motor from fluid ingress. The filling fluid used is potentially biodegradable and environmentally safe.
Cable lengths are available in length increments of 10 metres. The A-model is equipped with a float switch and plug.
Seal
Sealing on the fluid side is achieved by a bidirectional mechanical seal, while sealing on the motor side is achieved by a rotary shaft seal.
