Our highly advanced subsurface sucker rod pumps are meticulously crafted in strict adherence to API 11AX standards, proudly boasting the prestigious API monogram and ISO 9001 certification. With cutting-edge technology first integrated from the USA in the 1980s, our product line offers an impressive array of over 40 models and sizes. These pumps cater to diverse needs with diameters available from a precise 28 mm to a robust 108 mm, ensuring the perfect fit for every application.
The Sucker Rod Pump, elegantly referred to as the insert rod pump, represents a quintessential element of conventional sucker rod pump systems. Ingeniously designed to connect directly to the sucker rod, it facilitates effortless extraction alongside the rod, leaving the tubing untouched. This design innovation not only streamlines well inspections and workovers but also significantly reduces downtime and costs associated with pumping tests. As a result, the rod pump emerges as the ideal choice for operations in deeper wells, delivering efficiency and cost-effectiveness in the oil extraction process.
Featuring a sophisticated suspension structure, this pump barrel is engineered to enhance load-bearing capabilities, making it exceptionally suited for deep-well operations. This advanced pump boasts a setting depth range of 500 to 1500 meters, optimizing performance in challenging conditions. Its design incorporates a gap bridge structure to prevent bending, strategically suspending the barrel in the outer section to eliminate pressure and bending risks. The minimized plunger-barrel space reduces eccentric wear, significantly prolonging service life while ensuring superior pump efficiency. Furthermore, the precise eccentric distance ε=0 ensures reduced pump loss, making this pump the perfect solution for deep wells requiring extended tail pipes.
