Standard pumping unit is in line with the national standard of China. Shengji standard pumping unit consists of a different of types of pumping units. These include compound balanced pumping, double horsehead pumping unit and reversing pumping unit. These are new types pumping units based on the conventional beam pumping unit (except reversing pumping unit). The special structure of pumping unit can effectively: reduce the peak current & peak torque, reduce power consumption effectively and prolong the operational lifetime of the reducer. Shengji compound balanced pumping can achieve different crank angle of the upper and lower strokes, and ultimately achieve the running mode by going up slowly and going down quickly, This running mode is suitable for heavy oil production, The structure of double horse head makes the length of the latter arm changing all the time, This change matches the load change. As a result, this kind of pumpingunit can save electric energy significantly.

Key Features:-

• Reduce the power consumption effectively
• Suitable for heavy oil production
• Long and low stroke frequency.
• Less adjustment of stroke length and stroke ratio
