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.

The sucker rod pump is driven by the motive power transmitted by pumping unit or sucker rods to pump out fluid in oil wells. The products comply with Technical Specifications on Underground Rod-Type Oil Well Pumps and Accessories (API Spec 11AX), and have acquired the authorization to use Official API Monogram. Besides standard tubular and sucker rod pumps, the company also produces anti-gas/sand/salt/carbon powder pumps, across bridge pumps, inclined well pumps and other special oil well pumps.

Sucker rod, as one of the key component of rod pumping equipment, using sucker rod string to transfer energy in the process of oil production, serves to transmit surface power or motion to downhole sucker rod pumps.

Conventional API C pumping units with walking beams, balanced by cranks, are among the most common and most widely used power units in rod oil production. The pumping products comply with Specifications of Pumping Units (API Spec 11E) and other related standards, and have acquired the authorization to use Official API Monogram.
