Detailed Product Description

Progressing Cavity (PC) Pumps

• PC Pumps has been the fastest growing form of artificial lift in the world and Prime has been a leader in sales and service since the onset of this exciting technology in china.  With an install base of more than 200 pumps in China alone, Prime has gained vast experience in a wide variety of applications, including viscous crude, high gravity oils.
• Surface Drive and PC pump (Progressive Cavity Pump) is a new type of artificial lift system, which finds more and more applications in the oil fields. Surface drive suspends and rotates rod string and power is then transmitted downhole, which in turn drives the PC pump.
• PC pump consists of two parts: rotor and stator. The high strength, chrome-plated rotor is the only moving part of the PC pump. The stator is a kind of tube with elastic synthetic rubber molded inside. A variety of elastomer is available for different applications. When rotor rotates in the stator, a series of sealed cavities are formed and these cavities move axially from the intake end to the displacement side. When one cavity disappears at the displacement side, a new cavity will form at the intake side. Trough continuous formation, motion and disappear of these cavities, fluid is then brought to the surface. Owing to their unique features, the surface drive and PC pump find wide applications in the oil fields, and they are strongly recommended for high viscous, sandy, gassy and water bearing oil.
