Experience the precision engineering of Goldenman Petroleum Equipment Co., Limited's subsurface sucker rod pumps, crafted meticulously to meet the rigorous standards of API 11AX. Proudly bearing the API monogram and ISO 9001 certification, these pumps embody technological advancements introduced from the USA since the 1980s. With an impressive portfolio of over 40 models and sizes, these pumps offer versatility with diameters ranging from 28 mm to 108 mm, catering to a broad spectrum of oil extraction demands.
Discover the remarkable efficiency of the Sucker Rod Pump, also recognized as the insert rod pump-an innovative variant within the conventional sucker rod pump family. The rod pump integrates seamlessly with the sucker rod, enabling effortless extraction without impacting the tubing, thus facilitating more efficient well inspections and maintenance endeavors. Its design excellently halves the time and cost associated with pumping tests, making it the ideal choice for deeper wells.
Engineered with a sophisticated suspension structure, this pump barrel enhances the load-bearing capability, ensuring optimal performance even in deep well applications. Designed to operate at depths reaching 500-1500 meters, this pump features a gap bridge structure to prevent bending, with the barrel elegantly suspended within the outer section to negate pressure and minimize bending risk. The strategically managed space between the plunger and barrel mitigates eccentric wear, significantly extending the pump's service life and boosting efficiency. With a perfectly aligned eccentric distance of ε=0, the design effectively reduces pump loss, making it exceptionally suited for deep wells, particularly those requiring additional tail pipe installations.
