1.1 Product description, general
The KESSEL backwater pumping station Ecolift (referred to as the backwater pumping station from here
onwards) has been designed for pumping off wastewater with and without sewage. The assemblies for the
pumps, pressure sensor, motor-driven backwater flap and hinged flap (emergency closure) are installed in the
wastewater tank.
The hinged flap serves as a manually operated emergency closure. It can also be equipped with a motor. This is
then driven by a separate control unit which communicates with the control unit of the backwater pumping station.
In normal operation, the wastewater passes through the backwater pumping station to the sewage channel
without any backwater occurrence.
If the wastewater from the sewage system swells back as far as the backwater pumping station, this will be
detected by an optical probe. The motor-driven backwater flap is closed. The wastewater from the building is then
collected in the wastewater tank.
The sensor switching signals for the level in the wastewater tank are processed electronically in the control
unit. An optical probe is used as a level sensor. When the corresponding level has been reached, the pump-off
function is activated. The water is pumped off beyond the backwater level.
In the event of power outage, the functional safety of the motor-driven backwater flaps can be guaranteed for
about 2 hours during which they are battery-operated. After this period, the backwater flap is closed to protect the
building.
