Recently, Tianjin Shuangjin Pump Machinery Co., Ltd. has attracted widespread attention in the fields of shipbuilding and Marine engineering with its independently developed series of Marine Freshwater Pumps and Marine Centrifugal Pumps. As a leading domestic supplier of fluid equipment, the company has successfully developed pump solutions that are highly efficient, reliable and environmentally adaptable by introducing advanced foreign technologies and deepening cooperation among industry, academia and research. These solutions provide core support for ship power systems and fresh water supply.
Technological breakthroughs: From gear design to safety valve optimization
In the core product NHG series gear pumps, the company adopts advanced round tooth gear technology, significantly enhancing operational smoothness and noise control levels, while also extending the equipment’s lifespan. The design of its inner bearings is specially optimized for the transportation of lubricating fluid to ensure stable operation under the complex working conditions of ships. The shaft seal system integrates dual guarantees of mechanical seals and packing seals, while the infinite reflux design of the safety valve (opening pressure = working pressure +0.02MPa) strictly adheres to pressure safety standards, providing reliable protection for Marine equipment.
Application scenarios: Covering the entire life cycle requirements of ships
The company’s products can convey non-corrosive media such as lubricating oil, mineral oil and synthetic hydraulic oil, and are also compatible with special lubricating liquids such as light fuel and emulsion. In the field of ships, Marine Centrifugal Pumps, with their highly efficient fluid conversion capabilities, are widely used in power system cooling and bilge drainage. The Marine Freshwater Pump, through high-precision conveying technology, ensures the domestic water supply for ships and the cleaning needs of equipment. In addition, the product also performs outstandingly in industrial scenarios such as power plants and petrochemicals, demonstrating its multi-field adaptability.
Enterprise strength: Innovation-driven and global services
As a high-tech enterprise in Tianjin, Tianjin Shuangjin Pump Machinery Co., Ltd. has a full range of product lines including single-screw pumps, twin-screw pumps and centrifugal pumps. Relying on a professional R&D team and an information management system, it has accumulated a number of national patents. The company not only provides customized fluid solutions for high-end users, but also undertakes the maintenance and drawing tasks of high-end foreign equipment. The technology of its products has reached the international advanced level.
In the future, the company will continue to focus on technological innovation in Marine pumps, promoting the industry’s development towards green and intelligent directions, and injecting stronger impetus into the global shipbuilding industry.
