API Certified Pumping Units Manufacturing

The pumping unit is a key equipment that drives the sucker rod pump through the ground driving device to extract crude oil from the oil well to the surface.

Engineered as the backbone of sucker rod oil extraction systems, API C-Series pumping units represent the pinnacle of conventional walking beam technology. These ground power systems are precision-engineered to:
- Deliver consistent rod loads ranging from 22 kN to 180 kN (API 11E Class 2-4)
- Operate reliably in harsh onshore environments with 99%+ uptime potential
- Meet the rigorous demands of API Spec 11E, Official API Monogram License.
