Abstract
A positive displacement wave pump assembly for pumping liquid or gaseous or plastic fluids or mixtures thereof with solids or the like, including an elongated cylindrical tube or barrel having an upstream end and a downstream or discharge end, a drive shaft rotatable in portions of the barrel adjacent the upstream end, and a positive displacement wave pump is located in the barrel near the outlet end having a stator frame and a rotor member rotatable therein coupled to and driven by the driveshaft. The rotor member has an outer surface of developed helical coutour providing a plural turn helical thread of wide rounded form to position a stack of slidable sealing discs guided for diametric sliding movement by the rotor passing therethrough to form a seris of pumping pockets which progress longitudinally through the pump.
