Progressive Cavity Pumps

The PC Pump with surface drive is a new type of production equipment, which is consisted with surface drive equipment and downhole progressive cavity pump. The surface drive equipment transmits the power to the downhole through the rotating motion of suck rod, then drive the rotor to rotate in the stator downhole. PC pump is a positive displacement pump. The rotor rotates within the stator, thus series of cavities are formed and these cavities progress gradually from the bottom (suction end) to the top (discharge end), carrying the formation fluids through the pump and into tubing.
