HSBC Machinery has developed a completely leak-free sealed industrial pump

Since the domestic non-leakage sealing technology--mechanical seal applied to industrial pumps, many pump plants in China have used mechanical seals in the sealed part of the pump, but the effect is not satisfactory, especially in the coal washing industry, because the liquid solid particles are transported by the pump. Many, poor operating conditions, mechanical seals are sometimes not as reliable as packing seals, so China's medium pump seal technology has always been the world of packing seals, sealing effect is far behind and imported pumps.

China University of Mining and Technology takes the responsibility of revitalizing the national industry and takes the initiative to undertake the mission of developing a leak-free medium pump. Based on the international advanced sealing theory and years of practical teaching experience, the China University of Mining and Technology adopts a combined sealing technology with mechanical seal and auxiliary impeller seal. In 2002, it cooperated with Shandong HSBC Machinery Group Corporation to develop a “drip-free” slurry pump and circulating water pump. Filled the blank of domestic leakage-free sealing technology.

Nowadays, HSBC Group Corporation has developed a series of non-leakage slurry pumps and circulating water pumps based on this "non-leakage sealing technology" and is the only medium pump manufacturer to say goodbye to packing seals in China.
