Brief Introduction of the C-serise walking beam crank balance pumping unit/pump jack

In order to adapt to the development of petroleum industry, our company developed an pumping unit of beam-balanced serial in combination with the factual situation of our domestic oil field, aiming at the development direction of pumping units of deep pumping, long stroke and energy-saving, which are needed by such oil fields as not being able to perform flowing based on their oil layer energy.

Technical Performances of the pump jack

1)Walking Beam Balance/Crank balance

2)Retarder Adopting Double-circular-arc Helical Gearing System

3)24600lbs Rating Polished Rod Load

4) Stroke 36in
