API C Pumping Unit

Conventional API C pumping units with walking beams, balanced by cranks, are among the most common and most widely used power units in rod oil production. The pumping products comply with Specifications of Pumping Units (API Spec 11E) and other related standards, and have acquired the authorization to use Official API Monogram.

Pumping UnitFEATURES

- Modular and virtual manufacturing technologies are adopted in design, so that the structure of products is optimized and components are highly standardized, generalized and seriated. 
- Key structural elements are subject to finite element analysis to ensure stable performance and high reliability.
- Reducers are driven by double-arc symmetrical split or involute herringbone wheels that are properly sealed and distinguished with low noise, smooth operation, reliable and durable service.
- The entire machine features simple operation and maintenance and extended service life.
