Our subsurface sucker rod pumps are expertly crafted in accordance with the prestigious API 11AX standards. Proudly adorned with the revered API monogram and certified with the esteemed ISO 9001 license, these pumps are a testament to our commitment to quality and excellence. Originally, we embraced cutting-edge technology from the USA in the 1980s, a foundation that has allowed us to expand to over 40 diverse models and sizes. These robust sucker rod pumps boast a versatile diameter range from 28 mm to 108 mm, ensuring a perfect fit for every unique application.
Known in the industry as the insert rod pump, the Sucker Rod pump is a vital component in conventional sucker rod operations. Ingeniously designed to connect directly to the sucker rod, it can be seamlessly extracted without interfering with the tubing. This ingenious configuration streamlines well inspections and workovers, making them more convenient and efficient. By cutting the cost and time involved in pumping tests by half, the rod pump emerges as the ideal choice for deeper wells, optimizing productivity while minimizing operational expenses.
Featuring a sophisticated suspension structure, this pump barrel is engineered to enhance load-bearing capacity, making it highly effective for deep well operations. With a setting depth ranging from 500 to 1500 meters, this pump excels in delivering reliable performance in challenging environments. Its innovative gap bridge structure prevents bending, with the suspended barrel enduring no pressure, thus resisting deformation. The reduced space between the plunger and barrel significantly decreases eccentric wear, extending service life, and bolstering pump efficiency. Moreover, with an eccentric distance of ε=0, pump losses are minimized, making it ideal for deep wells where additional tail pipes are essential.
