Need Expertise on Progressive Cavity Pumps?


A PC Pump is a type of pump that uses a single-threaded, external helix (rotor) turning within a double-threaded internal helix (stator). This design allows for a low shear pumping action ideal for multiphase fluid transfer without degrading or emulsifying the fluids.

Traditional fluid transfer requires separation equipment, which can be costly to install and maintain. PC Pumps can transfer oil, gas and water through a single pipeline without degrading or emulsifying the fluids, making them an efficient solution.

Traditional pumps often struggle with rapidly fluctuating gas-to-liquid ratios, cannot handle suspended solids like sand and may have difficulty with varying API gravities. They can also emulsify fluids, complicating the separation process.

PC Pumps can increase production, even from marginal wells by significantly reducing wellhead pressures.

Yes, the Moyno Tri-Phaze System, for instance, can handle high gas volume fractions, high sand percentages, aromatics, changes in API gravity and H2S gas.

The spiral flow and low shear pumping action of PC Pumps ensure that shear-sensitive liquids are transferred without degradation.
