In the field of fluid transportation, screw pumps have become the standard equipment in the industry due to their high efficiency and stability.Tianjin Shuangjin Pump Industry Machinery Co., LTD. (hereinafter referred to as Shuangjin Pump Industry), established in 1981, is an industry benchmark.Its three core products - rotor screw pumps, worm screw pumps and Marine screw pumps - are reshaping the standards of fluid transportation with differentiated technologies.
Rotor screw pump: A silent and efficient lubrication expert
The rotor screw pump adopting circular gear technology keeps the operating noise at the lowest level in the industrial grade.The internal bearing design, in combination with the mechanical seal system, enables the pump body to maintain zero leakage even under a 132% overpressure condition.It is particularly suitable for fields such as petrochemicals that have strict requirements for the transportation of lubricating fluids.Shuangjin Pump Industry has extended the service life of the pump body to 1.8 times the industry average through surface hardening treatment of materials.
Worm screw pump: A flexible butler for multi-viscosity fluids
The unique helical worm structure enables this pump type to handle fluids with viscosities ranging from 0.5 to 100,000cP.Its progressive cavity design allows for pulsation-free transportation, making it outstanding in sensitive industries such as pharmaceuticals and food.The latest composite sealing system developed by Shuangjin Pump Industry has reduced the failure rate of the pump body in media containing particles by 67% compared with the previous year.
Marine screw pumps: The steel guardians of the Marine environment
The Marine screw pump specially designed for ships has passed the DNV-GL certification.Its safety valve supports infinite backflow protection and can still operate stably under extreme temperature differences ranging from -30℃ to 120℃.The bilge pump solution provided by Shuangjin Pump Industry for an international shipping group has increased the fuel transportation efficiency of ships by 22% and was awarded the title of Innovative Product for ship Equipment in 2024.
Shuangjin Pump Industry: The core strength with 40 years of technological accumulation
As the only domestic enterprise with a full range of screw pump testing platforms, Shuangjin Pump Industry has an annual production capacity of 120,000 units, and its R&D center holds 47 core technology patents.The chairman of the company stated at a recent industry summit: We are integrating intelligent sensing technology into the new generation of pump bodies and expect to achieve full coverage of predictive maintenance functions by 2026.
