Our subsurface sucker rod pumps are crafted with precision, adhering strictly to API 11AX standards. Proudly bearing the prestigious API monogram and the ISO 9001 certification, these pumps showcase our commitment to quality and excellence. Since acquiring cutting-edge technology from the USA in the 1980s, we've expanded our range to offer over 40 distinct models and sizes, with diameters ranging from an efficient 28 mm to a robust 108 mm.
Known in the industry as the insert rod pump, our Sucker Rod Pump represents a pinnacle of conventional sucker rod pump design. Directly connected to the sucker rod, this pump can be effortlessly extracted without disturbing the tubing. This design significantly streamlines well inspection and maintenance, resulting in substantial time savings and cost reduction during pumping tests. Ideal for deeper wells, this pump is engineered to provide superior efficiency and ease.
Featuring an innovative suspension structure, our pump barrel is designed to enhance load bearing capabilities, optimizing performance in deep wells with setting depths ranging from 500 to 1500 meters. Key features include a gap bridge structure to prevent bending, ensuring the barrel remains suspended without pressure, minimizing bending risks. The intelligently spaced plunger and barrel reduce eccentric wear, prolonging service life and optimizing pump efficiency. The eccentric distance ε=0 further minimizes pump loss. Perfect for deep wells requiring additional tail pipes, this pump is engineered for reliability and peak performance.
