Our subsurface sucker rod pumps exemplify superior craftsmanship, having been intricately engineered in strict compliance with API 11AX standards. These pumps proudly bear the API monogram and are ISO 9001 certified, assuring unwavering quality and reliability. With technology sourced from the USA since the 1980s, we offer an impressive portfolio of over 40 distinct models and sizes. These pumps boast a versatile diameter range from 28 mm to 108 mm, catering to diverse operational needs.
The Sucker Rod Pump, also acclaimed as the insert rod pump, represents a pinnacle in conventional sucker rod pump technology. This ingenious rod pump is seamlessly integrated with the sucker rod, allowing for streamlined extraction without disrupting the tubing. This innovation facilitates more efficient well inspections and workovers, slashing operational times by half and significantly curtailing pumping test expenses. Particularly adept for deep well applications, the rod pump is your go-to solution for enhanced efficiency and cost-effectiveness.
Engineered for excellence, this pump barrel features a sophisticated suspension structure that amplifies load-bearing capacity, making it a perfect fit for deep well operations. Capable of reaching depths between 500 and 1500 meters, this pump is designed to excel. Its unique characteristics include a gap bridge structure that mitigates bending, with the barrel suspended in the outer section, ensuring it bears no pressure and remains resilient to bending. The minimized space between the plunger and barrel diminishes eccentric wear, prolonging service life and boosting pump efficiency. The calculated eccentric distance ε=0 eliminates pump loss, rendering it ideal for deep wells requiring extensive tail pipe suspension.
