Our subsurface sucker rod pumps, crafted with precision, adhere to the esteemed standards of API 11AX, proudly bearing the API monogram and ISO 9001 certification. Since the transformative 1980s, when we embraced cutting-edge technology from the USA, we've expanded our offerings to boast over 40 unique models. These exceptional pumps range in diameter from a sleek 28 mm to a robust 108 mm, ensuring versatility and outstanding performance for every oil extraction need.
Known in the industry as the insert rod pump, our Sucker Rod Pump exemplifies the pinnacle of conventional sucker rod pump technology. Ingeniously connected directly to the sucker rod, this pump can be seamlessly extracted without disturbing the tubing, making well inspections and maintenance far more efficient and cost-effective. Its innovative design slashes operational time and expenses, making it the ideal choice for deeper wells, where reliability and performance are paramount.
Utilizing an advanced suspension structure, this pump barrel is engineered to optimize load bearing capabilities, making it exceptionally suited for deep well operations, ranging from 500 to a remarkable 1,500 meters. Key features include a gap bridge structure to prevent bending, ensuring the barrel remains suspended without pressure, thus minimizing wear and prolonging the pump's lifespan. The strategic design of the plunger and barrel interface reduces eccentric wear and pump loss, guaranteeing enhanced efficiency. Perfect for deep wells that require extended tail pipes, this pump delivers unparalleled reliability and performance.
