Our range of subsurface sucker rod pumps is crafted meticulously in strict compliance with API 11AX standards, proudly flaunting both the prestigious API monogram and ISO 9001 certification. Since the technological inception from the USA in the dynamic 1980s, we have expanded our offerings to include an impressive array of over 40 distinct models and sizes. These pumps boast a versatile diameter spectrum, ranging elegantly from 28 mm up to a robust 108 mm, ensuring a perfect fit for diverse operational needs.
Also known as the insert rod pump, the sucker rod pump stands out as a staple of conventional pumping technology. Ingeniously designed, the rod pump connects seamlessly to the sucker rod, allowing for hassle-free extraction alongside the sucker rod without disturbing the tubing, thus revolutionizing well inspections and workovers. With its efficiency in reducing labor time and testing costs by half, this pump emerges as an ideal choice for deep well applications, making it a cost-effective investment for challenging depths.
Engineered for excellence, this pump barrel employs a sophisticated suspension structure, optimizing its load-bearing capabilities for efficient performance in deep wells. It operates proficiently at depths between 500 and 1500 meters. Key features include a gap bridge structure to prevent bending, with the barrel artfully suspended in the outer section, minimizing pressure and bending risks. The strategic spacing between plunger and barrel curtails eccentric wear, vastly extending service life and boosting pump efficiency. Loss prevention is further enhanced with an eccentric distance ε=0, curtailing pump loss efficiently. This pump is the epitome of reliability for deep wells, particularly where extending tail pipes is necessary.
