1. Media: such as dewatered sludge (solid content: approx. 20-30%)
2. Abstract:
Dewatering of the sludge with the addition of conditioning additives into centrifuges, decanters or belt or filter presses generates a further reduction of volume between 65% and 80%. The result is a crumbly, compacted, non-flowing product.
Due to these features force feeding of the fluid within the pump is required. Furthermore, bridge-building has to be avoided.
In general, single screw pump with a rectangle feeding casing are used for this application. The special features of these pumps are the positioned, patented feeding screws for optional transfer into the conveying chamber. For sludge with a tendency to bride-building the progressing cavity pump is equipped with an integrated bridge breaker.
