Solid control system YZ-type liquid slurry pump is a vertical single-stage single-suction cantilever centrifugal pump structure, the impeller is semi-open impeller, the impeller has a side extension at the stirring blades. Main feature is the liquid part of the shaft, there is sufficient rigidity, the impeller, the pump is located between the bearing shell, do not use seal, can transport a large concentration of solid particles with the medium; maintenance-free, high temperature. Pump into the liquid between 800-1900mm in length, can be equipped with a suction pipe. By the vertical electric motor mounted on the motor seat, connected with the coupling and the pump. Direction from the motor, the pump is clockwise. Mainly used for pumping mud and silt residue containing the fluid and liquid materials.
