Our state-of-the-art subsurface sucker rod pumps are meticulously crafted in alignment with the prestigious API 11AX standards. Proudly bearing the API monogram and ISO 9001 certification, these pumps embody a legacy of excellence with technology sourced from the USA since the 1980s. We offer an impressive portfolio of over 40 distinct models and sizes, ranging in diameter from a compact 28 mm to a robust 108 mm.
Often referred to as the insert rod pump, the sucker rod pump stands as a paragon of conventional pumping solutions. Ingeniously connected directly to the sucker rod, it allows seamless extraction without affecting the tubing, ensuring smoother well inspections and workovers. This design innovation significantly slashes the time and cost of pumping tests, making it an ideal choice for deep well applications.
Featuring an advanced suspension structure, this pump barrel revolutionizes load-bearing efficiency, enabling optimal performance even at depths ranging from 500 to 1500 meters. Crafted with precision to prevent bending, the ingenious gap bridge design suspends the barrel in the outer section, thus eliminating pressure and reducing the risk of bending. The minimized space between the plunger and barrel counteracts eccentric wear, extending service life and boosting pump efficiency. With a calculated eccentric distance of ε=0, loss is minimized, making this pump perfect for deep wells requiring extensive tail pipe installations.
