The DZJ single-shell slurry pump is a new-generation slurry pump for washing and sorting developed based on the two-phase flow slurry pump design theory. It is a novel, high-efficiency, energy-saving, and abrasion-resistant slurry pump developed by integrating the pump requirements of various washing and sorting equipment, as well as the actual working conditions and pump usage of mining, coal washing, metallurgy, and other enterprises. This pump is mainly suitable for matching various washing and sorting equipment, transporting slurry with abrasive solid particles for industries such as washing, power, metallurgy, coal, and building materials. The weight concentration of its slurry can reach: 45% for ash slurry and coal slurry, 60% for ore slurry and heavy medium slurry, and can be connected in series according to actual conditions. This product has a simple structure and easy maintenance.
