The company consists of four branches: Hydraulic Pump Branch, Hydraulic Valve Branch, Hydraulic System Branch and Casting Branch. Including high-pressure piston pump, vane pump,gear pump, hydraulic valve, motor, hydraulic cylinder, hydraulic system and castings. They mainly used in engineering machinery, agricultural machinery, transportation (locomotives, rail transit, ships), petroleum machinery, metallurgical steel, coal mines, marine engineering, aerospace, water conservancy and power, machine tool industry, chemical equipment and other fields. The company has provided products for national key projects such as the Three Gorges Project, the South-to-North Water Transfer Project, the localization of metallurgical slab continuous casting and rolling production line and so on. The company continues to strengthen innovation drive, products and technology continue to expand to high-end manufacturing. Substantial breakthroughs were made in the localization of high-end high-pressure plunger pumps; High-pressure valve and multi-way valve break through the difficult problems of operation reliability and sealing technology under high pressure, high temperature and high frequency and reach the leading level in China. The technology of hydraulic-electro-mechanical occupies a leading position in China and undertakes the hydraulic system project of hoist and ship lift of all national key water conservancy and hydro-power projects, including the three gorges project; It has overcome the difficulties in the main hammer oil cylinder and hydraulic control technology and technology, and successfully matched the first set of hydraulic Marine pile hammer which is TZ researched and developed, and filled the blank in the field of hydraulic control technology of pile hammer. The company has established a complete quality management system, with the certification of informatization and industrialization "two-oriented integrated management system", and comprehensively implemented refi
