Description:

The belt pumping unit had the patent of American. It takes full advantages of all pumping units by years of research and development. As a unique engineering breakthrough, the 100% mechanical ROTAFLEX is especially suitable for producing high volume fluid in deep wells with rod pump. We had developed to seven types. Lots of products had been exported to America, Argentina, Kazakhstan, Uzbekistan, Indonesia and other countries in addition to using well in Shengli, Daqing, Liaohe etc., and almost every big oilfield in China. The advantages are high efficiency, reliability and energy saving.

Main Advantages:

1.

Long stroke leads to more complete barrel filling, less fluid pounding. Slow period means less wear on downhole equipment and less direction reverse. The operational cost is reduced.

2.

A long life heavy duty belt transmission can absorb the shock during stroke reverse, thus effectively reducing the stress on downhole components, and rod strings run uniformly.

 

3.

The torque arm is only 0.46m, so the torque demand is greatly reduced, thereby, smaller prime mover and gear box maybe possible. Comparing to other artificial lift system, ROTAFLEX can cut down energy costs by 10% to 40%.

4. Optimum Structure Design, Safety and Convenience

Automatically braking equipment and two sets of brake systems (mechanical & gas) promise the unit absolutely safety. Enclosed unit design makes the unit convenience in shipping and workover, and safety also.

5. High Reliability and Low Maintenance

High reliability by using antifriction bearings, heavy duty belt, heavy load sleeve roller chains, mechanical balance and self-protection, carrying load evenly and perfect rigidity through optimum design.
