Surface Drive Progressive Cavity Pump

The surface drive progressive cavity pump consists of a surface drive and a downhole progressive 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.
Features:
1. Wide fluid range ,
2. No gas lock
3. High efficiency
4. Uniform output flow rate ,easily adjustable by changing drive head speed
Easy operation due to simple, compact and light weight design, low cost and low investment of the surface drive.
