The surface drive screw pump (PC pump) 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 sucker rod to drive the downhole progressive cavity pump. PC pump is a positive displacement pump whose rotor rotates within the stator and forms series of cavities which progress liquid gradually from the bottom (suction side) to the top (discharge side) and carry the formation fluids through the pump and into tubing.
