Crafted to perfection, our subsurface sucker rod pumps adhere to the highest standards of excellence, following the stringent API 11AX guidelines. Proudly bearing the revered API monogram and ISO 9001 certification, these pumps are the epitome of innovation, with technology originally introduced from the USA in the vibrant 1980s. Explore a versatile range with over 40 meticulously engineered models and sizes, featuring diameters spanning from a sleek 28 mm to a robust 108 mm.
Also known by its industry name, the insert rod pump, the Sucker Rod Pump stands as a quintessential type of conventional sucker rod pump. Ingeniously designed, the rod pump directly connects to the sucker rod, allowing for seamless extraction alongside the rod without disrupting the tubing. This innovative design simplifies well inspections and maintenance, significantly reducing time and costs associated with pumping tests. Ideal for deep wells, the rod pump is your efficient solution for enhanced operational convenience.
Revolutionizing deep well operations, this pump features an advanced suspension structure, optimizing load-bearing capabilities for supreme performance. Designed for depths ranging from an impressive 500 to 1500 meters, the pump incorporates a gap bridge structure to effectively prevent bending. Ingeniously suspended within the outer section, the barrel bears no pressure, minimizing bending risks. The strategic spacing between the plunger and barrel curtails eccentric wear, prolonging service life and boosting pump efficiency. Achieving a perfect eccentric distance ε=0, this design minimizes pump loss, making it an ideal choice for deep wells requiring extensive tail pipe installations.
