Recently, as a leading domestic manufacturer of fluid equipment, Tianjin Shuangjin Pump Machinery Co., LTD., a high-tech enterprise in Tianjin, has continuously provided high-precision and high-reliability fluid solutions for the petrochemical, food processing, pharmaceutical and other fields by leveraging its core technology advantages in positive displacement pumps, attracting industry attention.
It is reported that the company’s product line covers single-screw pumps, twin-screw pumps, three-screw pumps, five-screw pumps, centrifugal pumps, gear pumps, etc. Relying on the introduction of advanced foreign technologies, cooperation with domestic universities for development and the accumulation of multiple national patents, it has formed a significant competitive edge in the field of positive displacement pumps.
Compared with centrifugal pumps, its positive displacement pump has four core advantages:
it has an outstanding ability to handle high-viscosity fluids. At low speeds (500-2000 RPM), it can efficiently transport media such as mud and high-viscosity oil, avoiding the problem of sudden efficiency drop of centrifugal pumps when the viscosity exceeds 200cp.
the low-speed design (such as as low as 200rpm for single-screw pumps) can protect shear-sensitive media like emulsions and biological liquids, preventing medium separation or structural damage.
it is equipped with self-priming and dry operation functions, eliminating the need for pre-filling fluids and making it suitable for intermittent supply scenarios.
it has strong pressure stability and can provide a constant output flow rate, meeting the precise quantitative requirements of chemical batching, food processing, etc.
In terms of technological innovation, the company’s independently developed single-screw pump with a double-head screw design achieves the dual goals of efficient transportation of high-viscosity fluids and reduced shear damage to the medium. The five-screw pump further enhances the processing capacity of high-pressure and high-viscosity fluids through the coordinated operation of multiple screws. At present, the products have reached the advanced level in the industry and internationally, and many technologies have been granted national patents.
Looking ahead, as the requirements for fluid processing accuracy and reliability in the industrial sector continue to rise, the market demand for positive displacement pumps will keep growing. Tianjin Shuangjin Pump Machinery Co., Ltd. stated that it will continue to rely on its professional technical team, information management technology and advanced detection methods to optimize product design, provide more efficient fluid solutions for global users, and contribute to the high-quality development of the industry.
