Whenever there is a gradient from the drainage points to the sewer, a hybrid lifting station can be used as a backwater protection system. In normal operation, it uses gravity to drain water without any power consumption. Only in the event of backwater does it begin to pump the wastewater into the backwater loop, or directly back into the pipe down stream of the unit, so that the connected drainage elements can continue to be used.
At the same time, the integrated backwater valve prevents the ingress of water from the sewer into the building. Hybrid lifting stations therefore combine environmental friendliness and maximum efficiency with the advantages of a lifting station.
Environmental friendliness and efficiency
Since hybrid lifting stations only pump in exceptional cases, they are more environmentally friendly, cheaper to operate and require less maintenance than other lifting stations.
Minimal noise emissions
A hybrid lifting station makes no noise in normal operation – ideal for rooms thatare often used by people.
Drainage can take place safely with a hybrid lifting station, even in the event of a power failure. The integrated backwater valve remains functional thanks to the backup battery.
