Background

The submerged slurry pump is of a vertical single-stage single-suction cantilever centrifugal pump structure, the impeller is a semi-open impeller, and stirring blades are arranged at the extension of the suction edge of the impeller. The method is mainly used for pumping thick liquid, thick oil, oil residue, dirty liquid, slurry, mortar, flowing sand and flowing sludge of urban sewage channels, and fluid and corrosive liquid containing silt residues in the industries such as environmental protection, municipal engineering, thermal power plants, gas coking plants, oil refineries, steel works, mining, paper industry, cement works, food factories, printing and dyeing industry and the like.

The submerged slurry pump is in single-stage and single-suction cantilever structure, and is characterized by that its bearing seat, supporting seat and connecting pipe are used to connect hydraulic component of pump, the liquid is discharged from liquid outlet pipe component, the impeller of the pump is a semi-open impeller, and the extended position of impeller blade inlet is equipped with stirring blade. The discharge pipe assembly is directly connected with the pump body and is connected with the external pipeline through the fixing plate, and the discharge pipe is inclined due to the fact that the discharge pipe in the discharge pipe assembly is longer.
