Product Information

1. This pumping unit is one of the API C pumping units. The products are balanced by cranks, and are among the most common and widely used power units in rod production on oil fields. The products comply with Specifications of Pumping Units (API Spec 11E) and other related standards, and they have acquired the Certificate of Authority to use the Official API Monogram. 

2. Technical performance & characteristics：

1) Modular and virtual manufacturing technologies are adopted in designing, so that the structure of the products is optimized and components are highly standardized, generalized and serialized. 

2) Key structural elements are subject to finite element analysis to ensure stable performance and high reliability. 

3) Reducers are driven by symmetrical shunt involute or double-arc herringbone gears that are properly sealed and distinguished with low noise, smooth operation, reliable and durable service. 

4) The entire machine features simple operation and maintenance and extended service life.
