Progressive Cavity Pumps
A progressing cavity (PC) pump employs a positive displacement principle. A typical PC features a suction inlet which feeds into an elongated casing. Within this casing sits a helical 'worm' rotor and stator assembly. The rotor helix is shaped off-set to the stator creating cavity spaces in the assembly which are formed by temporary seals as the rotor contacts the surface of the stator. As the rotor begins to move in an eccentric fashion, the cavities form, draw in product and are 'progressed' along the assembly and the product is expelled through the discharge port.
Progressing cavity pumps are often installed for handling viscous fluids at high flow rates or where a high discharge pressure is required with a smooth flow. Typical fluids may include slurry, mashes, pulps, dough from waste water treatment plants, anaerobic digestion facilities and paper recycling plants. As the pump flow rate is proportional to the speed the pump can be used for the dosing of viscous fluids such as additives and chemicals.

Working Principle
The PCP consists of a rotating eccentric screw (rotor) and the fixed‚ abrasion resistant‚ elastomeric lined casing (stator). In the cross-sectional plane‚ both are in contact with one another at two points‚ forming two sealing lines along the length of the conveying elements. The fluid entering the suction area of the casing enters a cavity which is being formed as the rotor turns. As the pump shaft continues to rotate‚ the cavity is sealed and the captured process fluid is displaced axially along the length f the casing to its ultimate exit point at the casing discharge . This smooth‚ continuous pumping action ensures an even‚ uninterrupted volumetric output from the pump and minimizes pressure pulsations at the pump discharge.
Applications
Progressing Cavity Pumps 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.
