Non-Flowable Dewatered Sludge / High Wear Resistance / Rotary Lobe
Pumps
A Accuvon Rotary Lobe Pump is used to transfer dewatered sludge
from a centrifuge. The non-flowable sludge is pressed into the pump
by a screw auger feed system. The electric motors of both the feed
screw auger and the pumps are controlled by a common frequency
inverter that is adjusted to the output of the dewatering machine.
