In the field of industrial pumping, the reliability, efficiency and cleanliness of sanitary screw pumps have become the core indicators for measuring the quality of systems. Tianjin Shuangjin Pump Industry Machinery Co., Ltd. is redefining industry standards with the outstanding performance of its SNH series three-screw pumps. This series of products adopts the authorized design of Allweiler from Germany. It achieves axial propulsion of the fluid through three precisely meshing helical rotors. Its positive displacement working principle ensures a pulsation-free and low-shear transportation process, making it particularly suitable for hygiene scenarios such as food and pharmaceutical industries where the integrity of the medium is strictly required.
In terms of technological innovation, the SNH series' unique spiral meshing cavity structure can effectively isolate the conveyed medium. Combined with material choices such as 316L stainless steel that meet FDA standards, the pump body is both corrosion-resistant and has a smooth surface. The laser welding and electrolytic polishing processes introduced by Shuangjin Pump Industry have further eliminated hygiene dead corners, increasing the efficiency of cleaning verification by 40%. The digital twin testing platform established by the enterprise can monitor the flow stability and temperature rise curve of the pump in real time, ensuring that the performance fluctuation of each piece of equipment leaving the factory is controlled within ±1%.
Market application data shows that the continuous operation time of this series of pumps on the aseptic filling line for dairy products has exceeded 8,000 hours, which is 15% more energy-efficient than traditional gear pumps. Its modular design enables rapid replacement of sealing components, reducing maintenance downtime to one-third of the industry average. The technical director of Shuangjin Pump Industry pointed out: We have optimized the rotor profile through fluid simulation, extending the viscosity adaptability to 1-100,000cP and solving the viscosity problem in the transportation of high-sugar sauces.
As one of the few domestic pump manufacturers that have passed the 3A hygiene certification, Shuangjin Pump Industry has built 12 GMP-level production lines for multinational pharmaceutical companies. Its customized services cover special requirements such as CIP/SIP cleaning system integration and explosion-proof motor selection. The customer satisfaction rate has remained above 98% for three consecutive years. With the enhanced requirements for equipment traceability in the new version of the "Good Manufacturing Practice for Pharmaceutical Products", the intelligent sensor system equipped on this series of pumps is becoming a new necessity for pharmaceutical customers.
