New Breakthrough in Screw Pump Design: Shuangjin Machinery drives the transformation of fluid transportation through technological innovation
Tianjin, October 9, 2025 - As a leading enterprise in China's pump industry, Tianjin Shuangjin Pump Machinery Co., LTD. (hereinafter referred to as Shuangjin Machinery) has once again pushed the technological boundaries of the industry through continuous innovation in the design of screw pumps. Its independently developed SNH series of three screw pumps and twin screw pumps have achieved technological breakthroughs by optimizing the shaft seal structure, bearing materials and heat treatment processes, reducing vibration and noise by 40% and extending bearing life by three times. These products provide more reliable fluid solutions for high-end fields such as petrochemicals and shipbuilding.
Technical core: Full coverage of scenarios from single-screw to five-screw
The screw pump product line of Shuangjin Machinery covers the entire series from single-screw to five-screw. Among them, the three screw pump adopts Allweiler licensed technology and achieves stable transportation of 760mm²/s high-viscosity media through a three-stage screw meshing design, with a pulsation shear rate 15% lower than the industry standard. The company's technical director pointed out: Through precision machining and gradient heat treatment processes, we have increased the strength of the pump shaft by 30%, while reducing the maintenance cost to one third of that of traditional products. This modular design concept reduces the number of parts by 25% and significantly lowers the wear rate.
Industry-university-research collaboration: Patented technologies forge industry benchmarks
Relying on its joint laboratories with domestic universities, Shuangjin Machinery has obtained 12 national patents. The variable pitch design technology of its twin screw pumps can dynamically adjust the flow rate according to the system capacity, with an efficiency of over 92%. The axial force balancing system independently developed by the company enables the product to maintain stable operation even under high-temperature conditions of 150℃. These innovative achievements have enabled it to be recognized as a high-tech enterprise in Tianjin for three consecutive years and become a core service provider for international high-end pump and valve maintenance.
Market layout: From "Made in China" to "Intelligent Made in China"
At present, Shuangjin Machinery's products have been exported to over 30 countries, and its customized fluid solutions cover fields such as energy, environmental protection, and pharmaceuticals. The newly launched five-screw pump series in 2025, through multi-screw collaborative design, further expands the application scenarios of ultra-high pressure working conditions. The general manager of the company stated: "In the future, we will continue to invest in research and development, taking the design of screw pumps as the core, to create Chinese standards in the global fluid transportation field."
