Our subsurface sucker rod pumps, proudly manufactured in full compliance with API 11AX standards, bear the prestigious API monogram and are ISO 9001 certified. Since the introduction of cutting-edge technology from the USA in the 1980s, our collection has grown to include over 40 meticulously crafted models and sizes of sucker rod pumps. With diameters ranging from 28 mm to a robust 108 mm, we ensure a comprehensive solution for diverse oil extraction needs.
Introducing the Sucker Rod Pump, also known as the insert rod pump, a remarkable variant of conventional sucker rod pumps. Ingeniously connected directly to the sucker rod, this pump can be effortlessly extracted alongside the rod, ensuring the tubing remains unaffected. This design innovation facilitates seamless well inspection and workover processes, significantly reducing downtime and saving costs on pumping tests. This makes the rod pump an ideal choice for deeper wells, where efficiency and cost-effectiveness are paramount.
Featuring an advanced suspension structure, this pump barrel enhances the load-bearing capability, making it highly effective for operations in deep wells with setting depths ranging from 500 to 1500 meters. Distinctive characteristics such as the gap bridge structure prevent bending, as the barrel is strategically suspended in the outer section to avoid pressure, thus mitigating bending risks. The minimized space between the plunger and barrel reduces eccentric wear, prolonging service life and guaranteeing superior pump efficiency. To further minimize losses, the design ensures that the eccentric distance ε=0, effectively reducing pump loss. This innovative pump is ideally suited for deep wells requiring extended tail pipe installations.
