Reciprocating diaphragm pump, commonly known as coal slurry pump or mineral slurry pump in the industry, is mainly used for slurry transportation in mining, non-ferrous metal and coal chemical industries. The industry usually divides high-pressure coal slurry pump and low-pressure coal slurry pump based on the pressure of 7~8mpa. The common high pressure is about 9~10mp and the low pressure is about 1~4mp.
In the field of coal chemical industry, the overall volume of diaphragm pump market is very small, the market is relatively monopolistic, and few enterprises participate. According to CMRC research statistics, the current market stock of high and low pressure coal slurry pumps is about 500 sets, and the annual sales volume is roughly between 100million yuan and 200million yuan. Among them, the high-end diaphragm pump market is basically occupied by foreign brands, with a market share of 90%, mainly by Netherlands Qihao and Germany firuwa; The medium and low-end diaphragm pump market is dominated by the local manufacturers Shenyang Zhongse and Chongqing water pump plant, accounting for about 80%.
At present, from the perspective of product application, some middle and low-end diaphragm pumps have been replaced by centrifugal pumps in the market, and it is expected that the number of low-pressure pumps will gradually decrease in the future. NFC Shenyang and Chongqing water pump plant will also further distribute the high-pressure diaphragm pump market. However, at present, the domestic high-pressure diaphragm pump market is more dependent on foreign investment, and most of the products are imported. To enter the field of high-end diaphragm pumps, domestic brands need to solve the problems of upstream supply of raw materials, processing quality and accuracy of parts, user preferences, installation and maintenance of diaphragm pumps, etc.
At present, the development of China's high-end equipment manufacturing industry is still in its infancy. National and regional policies support local enterprises to break through the "neck" problem in the high-end manufacturing field, including industrial robots, high-end cutting machines, high-end pumps, etc. In the future, as the gasifier in the field of coal chemical industry becomes larger and larger (up to 5000 tons at present), the supporting diaphragm pump will become larger and larger, and the challenges of domestic enterprises will also be upgraded.
