The surface drive progressing cavity pump consists of a surface drive and a downhole progressing cavity pump (PCP).The surface drive transmits power to downhole PCP through the rotating motion of the sucker rod. PCP is a positive displacement pump. The rotor rotates within the stator, thus series of cavities are formed and progress gradually from the suction end to the discharge end. The formation fluids are then forced continuously from downhole to surface.

The unit features apparent energy saving, long pump inspection period and wide range of well applications.It is suitable for high viscous, sand cut and gas well production, with displacement ranging from 1 to 400m³/d and maximum landing depth of 2000m. The company can safeguard that the most suitable stators solutions to be provided to customers, according to factors such as well fluid aromatic hydrocarbon and solid particle content, chemical compound existence of hydrogen sulphide and carbon dioxide and well temperature.
