Progressive Cavity Pump Manufacturers & Suppliers

A progressive cavity pump is also commonly known as a PC pump, screw pump (single-screw type), or Moineau pump — named after René Moineau, who invented the design in the 1930s. The term 'eccentric screw pump' is also widely used in industrial settings, particularly in oil and gas and wastewater treatment applications.

Progressive cavity pumps excel in handling viscous, abrasive, shear-sensitive, or multiphase fluids. Common applications include crude oil transfer, sludge handling, chemical dosing, mining slurries, dewatering operations, and food-grade fluid processing. Their consistent, low-pulsation flow makes them ideal where precision metering or gentle fluid handling is required.

A progressive cavity pump uses a helical rotor rotating inside a double-helix stator to create sealed cavities that progress from the inlet to the outlet. As the rotor turns, fluid is trapped in these cavities and displaced axially, producing a smooth, continuous, and virtually pulse-free flow regardless of pressure variations or fluid viscosity.

Progressive cavity pumps are widely used across oil and gas exploration and production, mining dewatering and slurry transfer, power generation facilities, and construction site water management. They are also applied in wastewater treatment, chemical processing, and food manufacturing wherever consistent flow and gentle handling of sensitive media are critical.
