Our subsurface sucker rod pumps stand as a hallmark of engineering excellence, crafted meticulously in accordance with the prestigious API 11AX standards. Proudly bearing the API monogram and ISO 9001 certification, these pumps epitomize quality and reliability. Since the 1980s, we've harnessed cutting-edge technology introduced from the USA, enabling us to offer an impressive array of over 40 distinct models and sizes. These pumps, with diameters ranging from 28 mm to 108 mm, cater to a myriad of applications, ensuring a perfect fit for every need.
Also known as the insert rod pump, the Sucker Rod Pump embodies the essence of conventional pumping systems, offering unmatched convenience and efficiency. Seamlessly connecting with the sucker rod, this pump can be effortlessly extracted without impacting the tubing, simplifying well inspection and workover operations. It not only halves the time required for pumping tests but also significantly reduces associated costs, making it an ideal choice for deeper wells where operational efficiency is paramount.
Engineered with a pioneering suspension structure, this pump barrel enhances the load-bearing capabilities, making it exceptionally suited for deep well applications. Designed to operate at depths of 500 to 1500 meters, this pump boasts a range of remarkable features. Its innovative gap bridge structure prevents bending, with the barrel suspended in the outer section, ensuring it remains pressure-free and resistant to deformation. The minimized space between the plunger and barrel curtails eccentric wear, thereby extending the pump's service life and elevating efficiency. With an eccentric distance ε=0, this design effectively mitigates pump loss, making it perfect for deep wells requiring extensive tail pipe installations.
