China University of Mining and Technology takes the revitalization of national industry as its own responsibility and takes the initiative to develop a non-leakage medium pump. Based on the international advanced sealing theory and years of practical teaching experience, the combination sealing technology with mechanical seal and auxiliary impeller seal is adopted. In 2002, it cooperated with Shandong HSBC Machinery Group Corporation to develop a slurry pump and circulating water pump that “drip water does not leakâ€. Filled the gap in domestic leak-free sealing technology.
Today, HSBC Machinery Group has developed a series of leak-free slurry pumps and circulating water pumps based on this “leak-free sealing technologyâ€. It is the only medium pump manufacturer in China that has bid farewell to packing and sealing.
HSBC Machinery has developed a complete leak-free sealing industrial pump
Since the domestic leak-free sealing technology--mechanical sealing application to industrial pumps, many pump factories in China have used mechanical seals for the sealing part of the pump, but the effect is not satisfactory, especially in the coal washing industry, because the liquid solid particles transported by the pump Many, the operating conditions are poor, the mechanical seal is sometimes not as reliable as the packing seal, so the Chinese medium pump sealing technology has always been the world of packing sealing, the sealing effect is far behind and the imported water pump.
