Product description
The backwater pumping station has been designed for pumping faecal and faecal-free wastewater. The assemblies for the
pumps, the optical probe and the motor-driven backwater flap are installed in the drain body.
In normal operation, the wastewater passes through the backwater pumping station to the sewage channel without any
backwater occurrence.
If the wastewater from the sewer system backs up as far as the backwater pumping station, this is detected by an optical
backwater probe (two optical probes as backwater probes - one each at the house and sewer end). The motor-driven back-
water flap is closed. The wastewater in the building then collects in the drain body of the backwater pumping station.
The switching signals of the sensors for the level in the drain body are processed electronically in the control unit. An opti-
cal probe is used for level detection. Once the relevant level has been reached, pumping via the drain body of the backwater
pumping station, against the incoming backwater, is activated.
In the event of a power outage, the functional reliability of the motor-driven backwater flap can be ensured for a period of
approx. 2 hours by means of battery mode. After this period, the backwater flap is closed to protect the building.
