Powerlift prefabricated pumping station
If the water level reaches the baseload (BL), then a pump switches on and pumps the
wastewater through the pressure pipe above the
“Pipe invert, backflow loop” level. From there
the wastewater flows by gravity to the drainage sewer.
Two ball retaining valves prevent backflow from the pressure pipe and into the tank.
If the water level falls to the pump OFF (OFF) level, then the pump switches off. With a set after-
running period (ARP), the pump remains activated and the water level continues to be lowered to
the after-running period OFF (ARP OFF) level.
The prefabricated pumping station is equipped with two pumps:
■
With each new start, alternating operation is executed.
■
If one pump fails, the second pump switches on.
■
If the wastewater inflow is higher than the delivery performance of one pump and the
water level rises to the peak load (PL) level, the second pump also switches on.
