Thickened sludge

An eccentric screw pump was installed on the thickened sludge side of a water extraction centrifuge. The maintenance costs were proving far too high for the customer. The pump also had to be completely dismantled for any repair work to be done.

Once the new rotary lobe pump was installed, the pump drive with a frequency converter was controlled by a signal from the sensor (hopper). The auger feed drive is run by a manually adjustable gear motor. This auger feed ensures that the pump always receives the optimum inlet pressure and amount. The steep walls of the hopper also prevent the build-up of sludge.
