Crafted to the exacting standards of API 11AX, these subsurface sucker rod pumps embody superior engineering and unmatched quality. Proudly bearing the prestigious API monogram and ISO 9001 certification, these pumps are a testament to Goldenman Petroleum Equipment Co., Limited's commitment to excellence since the technology's introduction from the USA in the 1980s. Our diverse selection boasts over 40 meticulously designed models and sizes, with diameters ranging from a compact 28 mm to a robust 108 mm, ready to meet every unique operational challenge.
The Sucker Rod Pump, also revered as the insert rod pump, represents an innovative facet of conventional sucker rod technology. Seamlessly integrated with the sucker rod, this pump can be effortlessly extracted without disrupting the tubing, streamlining inspection and maintenance processes. By slashing the time and cost associated with pumping tests by half, it emerges as a cost-effective solution ideal for deeper wells, offering unparalleled convenience and efficiency.
Engineered with precision, this pump barrel features a cutting-edge suspension structure, enhancing its load-bearing capacity to operate optimally in deep wells. With an impressive setting depth ranging from 500 to 1500 meters, this pump excels through its unique design attributes: the innovative gap bridge structure prevents bending by suspending the barrel in an outer section, eliminating pressure and reducing susceptibility to bending. The minimized space between the plunger and barrel curtails eccentric wear, significantly extending the pump's service life while boosting efficiency. With an eccentric distance ε=0, the optimized alignment curtails pump loss, making it an ideal choice for deep wells requiring additional tail pipes.
