API M Front-mounted pumping unit adopts crank-balance. The special structure reduces horsehead acceleration during upstroke, thus reducing static torque peak, increasing load capacity and saving energy. It is widely used in oil fields throughout the world. Our product accords with API Spec 11E Specifications for Pumping Units and Chinese petroleum industry standard SY/T5044-2003 and other related standards.
Performance and advantage
1)The gear reducer lies at the front of samson post. Impact structure, convenient operation and maintenance, longer service life;
2)Good balance effect reduces maximum torque of gear reducer. Energy-saving, smooth and stable operation;
3)The load carrying capacity is more reasonable; it is not easy for pitman arm or equalizer get fatigue damage; less mechanical wear and lower noise.
