What is surface drive?

The surface drive is a specific facility to suspend and rotate the sucker rod, which in turn drives the PC pumps. Then fluid can be brought to the surface by continuous movement of rotor within stator. When unit stops the surfaces drive absorbs reversion torque stored on sucker rod and releases the torque gradually so that thread off can be avoided. Since the stored energy is released, the safety of units and operation will be ensured. There are various PCP and surface drives and they are available for different well conditions.
