Progressive Cavity Pump Technology

Progressive cavity (PC) pumps provide smooth, low-shear, positive-displacement flow for viscous, abrasive, and solid-laden fluids. Their single-rotor, double-stator design creates sealed cavities that progress from suction to discharge, maintaining volumetric efficiency even with slurries up to 70% solids by weight.

With flow rates from 0.1 L/min to 500 m³/h and discharge pressures to 48 bar, our PC pump range covers chemical dosing, sludge transfer, polymer injection, and cake pumping duties. Modular designs allow quick replacement of rotor and stator without removing the pump from the pipeline.
