API Standard Pumping Unit

The beam pumping unit has features of reliable performance, simple structure, easy operation and maintenance etc.

Standard: API SPEC 11E standard.

Main features:

The whole unit has a reasonable structure, with the features of working smoothly, lower noise and easy maintenance.

 

Box type structure or "I" section structure has been adopted for the walking beam. It has features of high strength, good rigidity and high bearing capacity.

 

Gear reducer uses herringbone double arc gears, with the features of accurately machined, high bearing capacity and long working life.

 

The horse head can swing vertically or horizontally to both sides of the walking beam to facilitate work over operation.

 

External seizing structure has been adopted for the brake system and with the help of security device, the brake system has features of flexible operation , instant braking and reliable security; The base and the foundation can be fixed together by foundation bolts or compression bar.
