A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.

Aug 26, 2016 · Progressing cavity pumps (PCPs) displace fluid by transferring it through a sequence of small, discrete cavities formed from the turning of a helical rotor within a stator.

Progressing cavity pumps belong to the group of positive displacement pumps. The main components are a rotating rotor and a stationary stator. The rotor, hinged or elastically attached on one side, is a round-threaded screw. On the output side, the axial position oscillates. The hollow stator is elastic and has the same pitch length as the rotor.

Maximize production while leaving a minimal footprint with progressing cavity pump (PCP) systems. The KUDU PCP is a positive displacement pump with a range of models, elastomers, and rotor options to meet your specific application.

The CHIOR PCP is an electric motor-driven progressing cavity pump, consisting of a rotating rotor and a fixed stator, which serve as the primary conveying elements. The rotor is a single-threaded, elongated round-thread screw driven by the drive unit via a joint.

A PCM Moineau™ pump is a progressing cavity pump made of a single helix rotor inserted in a double helix elastomer stator. When the rotor turns, sealed cavities progress along the spinning rotor, moving the fluid from the intake to the outtake.

PCPs are positive displacement systems consisting of two components: a rotor and stator. During operation, the rotation the rotor combines with the precise elastometric geometry stator. The complex interaction of these two parts creates of cavities within the pump.

By rotating the rod string using a surface drive system, the rotor turns within the stationary stator, creating the pumping action required to deliver fluids to the surface. Due to the small outer diameter, installation is straightforward and cost-effective.

The quality of stator and rotor can directly or indirectly determine progressive cavity pumps service lives. Specialized in pump stator and rotor, Subtor has designed four types of stator and rotor for you to choose—type A, type B, type D and type P.

The PivotAL Progressing Cavity Pump (PCP) is designed with an extended stator and custom-milled rotor featuring alternating active and inactive sections every 12 inches. This design is strategically aimed at minimizing the workover frequency of wells experiencing diminished runtimes attributed to elastomer wear and fatigue.
