Progressing cavity pump
December 3, 2014
The NETZSCH NEMO progressing cavity pump is based on a multi-spiraled rotor running inside a matching negatively spiraled stator housing; the tight tolerances of the geometry of the 2 components creates conveying chambers of the same size on the suction side with each rotation, moving a sensitive medium to the discharge side in fixed volumes. Each portion is transported through the pump in its stable chamber and released back into the pipe on the discharge side. The pump chamber is designed to be free of dead space and the flow optimized to prevent pumped medium from adhering.
