Our subsurface sucker rod pumps, crafted with precision and dedication, stand in strict compliance with the prestigious API 11AX standards. Proudly adorned with the esteemed API monogram and backed by ISO 9001 certification, these pumps represent the epitome of quality and reliability. With technological roots introduced from the USA during the vibrant 1980s, we offer an impressive array of over 40 diverse models and sizes. Each pump varies in diameter, ranging from a compact 28 mm to a robust 108 mm, catering to a wide spectrum of oil extraction needs.
Commonly known as the insert rod pump, the Sucker Rod Pump exemplifies an innovative approach to conventional sucker rod pumping systems. Ingeniously connected directly to the sucker rod, this pump can be effortlessly extracted without disrupting the tubing, ensuring that well inspections and workovers are executed with unmatched ease and efficiency. This streamlined process not only slashes testing times by half, but also significantly cuts associated costs, making the rod pump an ideal choice for the challenging demands of deeper wells.
Engineered with a sophisticated suspension structure, this pump barrel enhances the load-bearing capacity, ensuring seamless operation even in the depths of challenging wells. Designed for depths ranging from 500 to 1500 meters, this pump exhibits remarkable features: To combat bending, the innovative gap bridge structure ingeniously suspends the barrel externally, shielding it from pressure and preventing deformation. The intelligent spacing between the plunger and barrel minimizes eccentric wear, thereby extending the pump's lifespan and optimizing efficiency. The carefully calculated eccentric distance ε=0 ensures minimal pump loss, rendering this pump an exceptional choice for deep wells where the extension of tail pipes is a necessity.
