The liquid-type slurry pump is a single-stage single-suction cantilever structure, and the impeller is a semi-open type. There is no bearing between the impeller pump casing, no shaft seal, no maintenance, can transport medium with large concentration and solid particles, large amount of suction, and wear-resisting alloy material for flow-through parts. Can be widely used in metallurgy, mining, power, coal, coal washing, chemical, petroleum and other industries. YZ-type liquid slurry pump under the depth of ≤ 2000mm.
