Crafted with precision, our subsurface sucker rod pumps are engineered in strict adherence to API 11AX standards. Proudly boasting the prestigious API monogram and ISO 9001 certification, these pumps are a testament to quality and innovation. Originating from cutting-edge technology introduced from the USA in the 1980s, we offer an impressive range of over 40 models and sizes, with diameters spanning from 28 mm to 108 mm, catering to diverse needs across the industry.
Known in the industry as the insert rod pump, the Sucker Rod Pump is a marvel of engineering within the realm of conventional sucker rod pumps. Seamlessly connected directly to the sucker rod, it facilitates effortless removal without disturbing the tubing. This design streamlines well inspections and workovers, significantly cutting down on time and costs associated with pumping tests. This efficiency makes it the ideal solution for deeper wells, offering both convenience and cost-effectiveness.
Ingeniously designed with a suspension structure, this pump barrel enhances load-bearing capabilities, making it exceptionally effective in deep wells. Capable of being set at depths ranging from 500 to 1500 meters, the pump exhibits superior features: A gap bridge structure that prevents bending by suspending the barrel in the outer section, thus eliminating pressure and minimizing bending risks. The strategic spacing between the plunger and barrel mitigates eccentric wear, thereby extending service life and optimizing pump efficiency. With an eccentric distance ε=0, pump loss is minimized, making it a perfect choice for deep wells that require extended tail pipe support.
