Also referred to as progressing cavity pumps, progg cavity pumps, PC pumps, and cavity pumps, these positive displacement pumps are designed to move fluids at the same velocity irrespective of the inlet pressure. Progressing cavity pumps draw fluid via a suction inlet and direct it into an elongated casing holding a helical rotor and stator assembly that discharges the fluid at steady velocity via the discharge outlet.
Most progressive cavity pumps come with accessory options to prevent the pump from running dry. Otherwise, the rotor and stator can generate too much heat, causing the pump to fail. Other advantages of PC pumps include their high suction lift, self-priming capability, and higher discharge pressures compared to many other positive displacement pumps.
With their high pressure and high suction lift capabilities, PCPs can be used in a wide range of applications, including:
- Dosing and Metering
- Pumping shear-sensitive fluids
- Pumping Abrasive Fluids
