The RWB is a fixed-barrel, bottom-anchored, thin-wall sucker rod pump. Featuring a thin-wall barrel paired with a bottom anchoring structure, it boasts a simple and compact design with stable, uniform displacement. It is highly suitable for large-scale production in conventional medium and shallow oil wells. With excellent versatility, this pump adapts to most standard production conditions. It has fewer wear parts and is easy to maintain, making it ideal for widespread deployment across oilfields. Overall, it serves as a highly cost-effective solution for fluid lifting in conventional oil wells.
Featuring a fixed-barrel, bottom-anchored design, this pump complies with API Spec 11AX and is ideal for medium-depth wells. The internal threaded barrel design maximizes production output within specified tubing sizes. The bottom-anchored structure allows for deeper pump setting, as the pressure balance between the barrel's outer diameter and the tubing's inner diameter eliminates the "barrel breathing" effect under formation pressure.
The pump barrel is lightweight and features a large internal drift diameter, fully conforming to API machining standards. Its smooth, burr-free inner wall minimizes friction during plunger travel, significantly improving lifting efficiency.
Core components—including the barrel, plunger, and sealing assembly—are highly interchangeable with other API pumps of the same specification, reducing maintenance and replacement costs. The pump's lightweight design eliminates redundant reinforcements, offering outstanding cost-effectiveness. Its simple, reliable sealing structure minimizes gas lock issues, making it perfect for large-scale deployment in conventional medium and shallow wells. Assembly, commissioning, and maintenance are highly straightforward.
The lightweight, large-bore thin-walled barrel minimizes friction during plunger operation, boosting lifting efficiency and reducing energy consumption in conventional medium and shallow wells.
The simple bottom anchoring mechanism features a compact design with no complex parts. This allows for easy installation and setting, significantly reducing downhole operation difficulty and shortening commissioning time.
Featuring a modular universal structure, its core components are highly interchangeable and compatible with API pumps of the same specification. This facilitates quick maintenance and replacement, effectively cutting spare parts procurement and operational costs.
The overall lightweight design offers outstanding cost performance, making it ideal for large-scale deployment in conventional medium and shallow wells with low comprehensive operating costs. Additionally, the bottom drainage valve prevents particle sedimentation and buildup on the pump, while significantly mitigating the adverse effects of corrosive fluids.
Featuring a quick-install bottom anchoring structure, it ensures precise setting and positioning. Pump inspection requires no special tools, which significantly boosts operational efficiency and minimizes well downtime.
The thin-walled barrel with a large bore design delivers stable displacement. It meets the high-volume lifting demands of medium and shallow wells, accelerating single-well recovery rates and boosting overall production capacity.
Its streamlined structure ensures a low failure rate, making it ideal for conventional wells with low sand content and non-corrosive fluids. Requiring no special maintenance, it perfectly supports stable daily production in oilfields.
