HU GANG was founded in 1998, headquartered in Shanghai, with a factory area of over 30000 square meters. It is a well-known professional manufacturer of jet vacuum pumps in China. The company is deeply engaged in the field of vacuum technology, with its main products covering three categories: jet vacuum pumps, mechanical vacuum pumps, and special-shaped screw dry vacuum pumps. It has formed a complete system of six series and nearly a hundred specifications, including water jet vacuum pumps, steam water series vacuum pumps, Roots water jet series units, water jet condensate pumps, vacuum deaerators and water diversion pumps, well point dewatering and soft foundation preloading vacuum units. The material selection is flexible and diverse. In addition to conventional cast iron, stainless steel, polypropylene, and internally rolled modified polyethylene (PE), we have also innovatively developed an internal coating process with imported polytetrafluoroethylene (F3) from the United States, which endows the product with excellent high temperature resistance and strong corrosion resistance, effectively meeting the strict working conditions of special industries.
