A new materials company in India operates a polyaluminum chloride (PAC) production unit. In the production process, three core stages must be completed: bauxite slurry transfer, hydrochloric acid dissolution reaction liquid circulation, and finished PAC product transfer. The operating conditions involve multiple severe challenges, requiring reliable and efficient industrial process pumps to ensure continuous operation and maintain product quality.<\/p>\n\n\n\n
First, the bauxite slurry contains a large amount of hard solid particles, with a solids concentration of up to 35%, and is accompanied by unreacted acidic impurities. This causes severe abrasion and corrosion to the pump wetted parts. Conventional pumps experience impeller wear and casing leakage in a short period of time and fail to meet continuous operation requirements.<\/p>\n\n\n
