Our state-of-the-art subsurface sucker rod pumps are meticulously crafted in compliance with API 11AX standards, boasting an esteemed API monogram and ISO 9001 certification. Since the 1980s, we've proudly integrated advanced technology from the USA, offering a diverse range of over 40 models and sizes. Our pumps feature diameters ranging from 28 mm to 108 mm, ensuring we meet a variety of operational needs across the oil industry.
The Sucker Rod Pump, also known as the insert rod pump, represents a pinnacle of conventional sucker rod pump technology. This pump is directly linked to the sucker rod, allowing for easy extraction without affecting the tubing, thus facilitating more efficient well inspections and workovers. This innovation effectively halves the time and costs associated with pumping tests, making it an ideal choice for deeper wells.
Featuring an innovative suspension structure, this pump barrel enhances the load-bearing capacity for optimal performance in deep wells. It can be set at depths ranging from 500 to 1500 meters. The pump's unique characteristics include a preventive gap bridge structure that suspends the barrel in the outer section, shielding it from pressure and reducing the risk of bending. The strategic spacing between the plunger and barrel minimizes eccentric wear, extending service life and ensuring superior pump efficiency. With an eccentric distance of ε=0, this design effectively reduces pump loss, making it perfect for deep wells requiring additional tail pipes.
