API DOWNHOLE SINGLE SCREW PUMP

Surface Drive and PC pump 

Surface Drive and PC pump (Progressive Cavity Pump) is a kind of high-efficiency and energy-saving artificial lift system used for oil production industry, which is composed of surface drive and downhole PC pump. 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 PC pump. Stator is a kind of tube with elastic synthetic rubber molded inside. A variety of elastomeric is available for different applications.
