Product description
The backwater lifting station is delivered with wastewater pumps of different capacities.
The switching signals of the sensors for the level in the wastewater tank are processed electronically in the control unit. A
pressure sensor is used as a level sensor. Pumping is activated when the fill volume has been reached. Depending on the
level reached, this is carried out by either one or both pumps. The water is pumped away either above the backwater level or
directly downstream of the backwater flaps.
In the event of a power outage, the functional reliability of the motor-driven backwater flaps can be ensured for a period of
approx. 2 hours by means of battery mode. After this period, the backwater flaps are closed to protect the building.
Different elements of the chamber system (010-701) can be mounted on the wastewater tank. Together with the functional
element mounted on it, the wastewater tank then represents the base element of the chamber system.
