Submersible slurry pumps, chemical submersible pumps, are single-stage, single-suction, cantilevered structures, connected by bearing housing, support bracket, and connecting pipes to the pump's hydraulic components. The liquid is discharged through the discharge pipe component. The pump impeller is a semi-open impeller, with agitator blades at the extension of the impeller blade inlet. The main feature of this pump is that the shaft in the submersible section has sufficient rigidity, with no bearings between the impeller and the pump casing, and no shaft seal used, allowing for the conveyance of media containing high concentrations of solid particles. The pump can be inserted into the liquid up to 800-2000mm in length, and an intake pipe can be provided upon request. The shaft seal is designed for larger pumps to operate submerged without a seal, with power transmission by a vertical motor mounted on the motor support and bracket, connected to the pump via a coupling. YZ type submersible slurry pump, SP type submersible slurry pump, ZJL type submersible slurry pump are vertical, single-stage, single-suction, cantilevered centrifugal pump structures. The impeller is a semi-open impeller, with agitator blades at the extension of the impeller suction side.
