API C Series Conventional Beam-Pumping Unit

Description

API C series beam-pumping unit adopts crank balance. It is the most common and most widely used ground power equipment in rod pumping work. 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:
> Modularization and virtual manufacturing technology have been adopted in the process of designing. Product structure has been optimized, and the parts are of high standardization, universalization, and serialization.
> Finite-element analysis has been adopted to the key structure to realize stable performance and high reliability.
> The reducer adopts symmetrical involute gear transmission or double circular arc herringbone gear transmission, with good sealing, low noise, smooth running and reliable durability.
> The unit has the characteristics of simple operation, easy maintenance and long service life.
