Our subsurface sucker rod pumps are meticulously crafted in strict adherence to the prestigious API 11AX standards, proudly bearing the revered API monogram and the esteemed ISO 9001 certification. Enriched with cutting-edge technology sourced from the USA since the 1980s, we offer an extensive array of over 40 distinct models and sizes to cater to your specific needs, with diameters ranging from a precise 28 mm to a robust 108 mm.
Often referred to as the insert rod pump, the Sucker Rod Pump exemplifies the pinnacle of conventional pump design. Seamlessly connected to the sucker rod, it offers the remarkable advantage of being withdrawn without affecting the tubing, ensuring maximum efficiency and remarkable ease during well inspections and overhauls. This innovative design not only saves time by up to 50% but also significantly reduces pumping test costs, making it an ideal choice for deeper wells.
This ingeniously crafted pump barrel employs a suspension structure that significantly enhances load-bearing capabilities, making it exceptionally suited for deep well operations. Designed for a setting depth of 500 to 1500 meters, the pump boasts remarkable features aimed at preventing bending through its innovative gap bridge structure. The barrel, suspended in the outer section, remains free from pressure, thereby reducing bending risks. With minimized eccentric wear thanks to the optimized space between the plunger and barrel, the pump's service life is extended, guaranteeing enhanced efficiency. Furthermore, the calculated eccentric distance ε=0 ensures minimal pump loss, making this pump perfect for deep wells requiring additional tail pipes.
