                                       API R series Pumping Units

      API R series Pumping Units is a new type energy-saving walking beam pumping units, it’s a new type of power equipment on the ground used in sucker rod oil extraction.

     The products conform to API Spec.11E “Specification for Pumping Units” and other relative API standards, acquired the authorization to use Official API Monogram.

 

Technical Performances 1,High reliability, simple operation, easy maintenance, long service life. 2,Use phase angle in crank arm in order to reduce the peak value of max. torque in gear reducer. 3,To improve power performance by increase the extreme location angle. 4,It can reduce motive power, saved energy obviously. 5,Gear reducer is involute herring-bone gearing, work smoothly and reliably.
