The WJ type slurry pump utilizes an advanced double-channel impeller from abroad, suitable for transporting slurry containing corrosive liquids at temperatures below 200°C, replacing traditional lined pumps. It boasts excellent performance for various fibers and particles, featuring non-clogging and a wide range of slurry concentration, applicable to cotton pulp, wood pulp, various particles, and wastewater garbage. Compared to the ZBJ pulp pump, it has a longer service life, significant energy-saving effects, and efficiency can be improved by 10-15%, especially when the flow section is made of materials like ZG1Cr18Ni9Ti, ZG1Gr18Ni12Mo2Ti, 316, 316L, 904, Cr30, 941, CD4MCu, etc. The WJ type slurry pump is a new generation of slurry pump series developed based on the non-clogging pump principle of the Japanese Hitachi Zosen.
