CHJ series is a special slurry pump for coal chemical industry which is resistant to high temperature, high pressure, corrosion and abrasion and meets API-610 design specifications. With the rapid development of China's coal chemical industry, the performance, reliability, service life and maintenance performance of high-pressure wear-resistant pumps in Texaco and Shell process equipment have become concerns of users. The Texaco unit is a lock bucket circulation pump and a washing tower circulation pump, and the Shell process is a slag tank circulation pump and a drainage booster pump. Combining years of research and development experience with slurry pumps, our company has developed a new type of high-pressure wear-resistant CHJ series pumps suitable for high inlet pressure, high temperature and wear resistance. The product is also used in high temperature, high pressure, corrosion and abrasion resistance stations such as slurry transportation, refineries, petrochemicals, etc.
