API spec 11E belt pumping unit for For heavy oil well production

 The belt pumping units is the patented product . It has mixed together major features and advantages of all kind of pumping units through years of research and development. As a unique engineering breakthrough, the 100% mechanical  is especially suitable for producing high volume fluid in deep wells with rod pump and heavy oil recovery. We had developed up to seven types. Lots of products had been exported to America, Canada, Cuba, Argentina, Kazakhstan, Uzbekistan, Middle East and other countries in addition to be using in Shengli, Dagang, Liaohe oilfield and almost every big oilfield in China. It has proved that the pump unit with the international advanced level combines the advantages of high efficiency, reliability and energy saving.

Main Advantages:

1. Slow, Long Strokes: Long stroke make high coefficient of fullness, less fluid pounding;Slow period means less wear on downhole equipments and little cost.
2. Belt Transmission: A long life heavy duty belt transmission can absorb the shock during stroke reverse, thus effectively reduce the stress on downhole components to make rod strings run smoothly.
3. Low Torque Demand: The torque demand is greatly reduced due to the short torque arm which is only 0.46m.
4. Optimum Structure Design, Safety and Convenience: Two sets of brake systems with the automatic braking device ensure the units safety absolutely
5. High Reliability and Low Maintenance: perfect rigidity through optimum design.
6. Auxiliary system is fairly complete, not only for high volume production, but also for deep wells low volume production.
