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
the switch-off level is reached, the pump is deactivated.
Pump chambers with two pumps operate according to the base load and peak load
principle. The pumps are switched on depending on the fill level. Depending on the
switchgear, pump cycling is carried out after every pumping procedure. If one pump
malfunctions, the other pump is automatically used.
