Screw Pump / Progressing Cravity Pumps
Progressing Cavity Pump (Screw pump) is an ideal transfer pump for decanter centrifuge. They have a very broad application range and are used in all branches of industry for the continuous, pressure-stable, gentle and low-pulsation conveyance of almost any substance. One advantage for the operator is that such a valveless positive-displacement pump is also capable of transporting stringy material safely.

Features of the Progressing Cavity Pump
-
continuous low-pulsation conveyance unaffected by fluctuations in pressure and viscosity
-
conveyance volume in proportion to rotation speed with high dosing precision over the entire rotational-speed range
-
high pressure capability without valves
-
location of the mechanical seal directly under the intake port in the pumping space makes external flushing of the seal unnecessary in many applications
-
short drive shaft and pump lantern offer high stability for mechanical seal installation
-
separate flange bearing and pump base make it easy to change the stator
