Recently, it was learned from Tianjin Shuangjin Pump Industry Machinery Co., Ltd. that the company has achieved a comprehensive upgrade in product accuracy, reliability and comprehensive solution capabilities of its SNH series three-screw pumps by relying on the advanced German Allweiler technology it introduced and making independent innovations. This marks a new stage in the research and application of high-end positive displacement screw pumps in China.
Technology leadership defines the high standards of the industry
As a classic positive displacement screw pump, the core of the SNH series three-screw pump lies in its exquisite screw meshing principle. The rotating screws inside the pump form a series of continuous sealed cavities through precise meshing, smoothly and pulsatingly pushing the conveyed medium towards the outlet, thereby providing an extremely stable pressure for the system. This series of pumps demonstrates an outstanding performance range: flow rates cover 0.2 to 318m³/h, working pressures can reach up to 4.0MPa, and they can handle various non-corrosive oils and lubricating oils with viscosities ranging from 3.0 to 760mm²/s.
In addition to its wide adaptability, this product also integrates multiple advantages: uniform and continuous flow, low vibration and low noise; It has a powerful self-priming ability; It is insensitive to gases and trace impurities that may be mixed in the medium and demonstrates outstanding robustness. It is particularly worth mentioning that its structural design is robust and flexible, allowing for various installation methods such as horizontal, flanged or vertical. Moreover, it can be equipped with heating or cooling devices according to customer requirements, fully demonstrating the highly modular and customized characteristics of modern volumetric screw pumps.
Deeply cultivate applications and solve industry problems
In response to the industry pain points of transporting high-viscosity media in fields such as petroleum, chemical engineering, and metallurgy, Tianjin Shuangjin Pump Industry, relying on its profound technical accumulation in the field of positive displacement screw pumps, has developed dedicated insulated screw pumps (insulated oil drainage pumps). This product is specially designed for transporting high-temperature and high-viscosity media such as asphalt and heavy fuel oil. It can be heated and insulated through heat carriers like steam and hot oil, ensuring stable and efficient operation under harsh working conditions. It has become a key piece of equipment in the production processes of many high-end users.
Innovation-driven development to build a national pump industry brand
Tianjin Shuangjin Pump Industry Machinery Co., Ltd. is not merely a simple product manufacturer, but also a provider of advanced fluid solutions. The company has gathered professional technical talents, equipped with advanced R&D and testing facilities, and has established in-depth cooperation with well-known domestic universities, thus forming a powerful independent R&D system. This continuous innovation capability enables the company not only to offer a full range of products such as single-screw pumps, twin-screw pumps, centrifugal pumps, and gear pumps, but also to undertake the maintenance of high-end foreign products and the task of domestic substitution. Many products that have obtained national patents have reached the international advanced level.
In the future, Tianjin Shuangjin Pump Industry will continue to delve into the cutting-edge of positive displacement screw pump technology, providing more precise and reliable products and solutions to serve the global industrial sector and contribute to the leap from “Made in China” to “Intelligently Made in China”.
