Chamber
Pump chamber with optimised geometry for deposit-free operation. Chamber compo-
nent with ribbing for high inherent stability and buoyancy safety. The inlets are freely
configurable. Two lifting eyes are integrated for attaching the lifting equipment. The
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

Level control
Depending on the type, the level is controlled via the float switch of the pump, a separ-
ate float switch or a level sensor. If the level is controlled with a separate float switch or
level sensor, it is controlled via switchgear.

The sewage produced is channelled into the pump chamber via the inlet, where it col-
lects. When the water level reaches the switch-on level, the pump is switched on. The
collected sewage is pumped into the on-site pressure pipe via the discharge pipe. When
