Hydraulically driven reciprocating piston pumps and progressing cavity pumps are used to pump dewatered cake.Hydraulically Driven Reciprocating Piston Pumps pumps use a twin screw auger feeder. The principal advantage is that they can move dewatered cake with up to 20% solids. We offer hydraulically driven reciprocating piston pumps in a range of capacities and discharge pressure capabilities -  up to 1500 L/min and 13.800 kPa respectively. There is also a wide range of suction feed hopper-to-pump configurations available.
