Mill discharge slurries, in particular, have large particle sizes and high concentrations, which shorten the life of the slurry pump's jacket. The jacket is a crucial component of the slurry pump's flow path, and its lifespan directly impacts the pump's lifespan.
[0003] Usually, the sealing between the sleeve and the front guard plate and the rear guard plate depends on the processing accuracy of the fitting parts or the ordinary round flat sealing rubber ring.

[0006] Preferably, a fixing plate is provided in the middle of the side surface of the first volute, and a fixing seat is provided through the middle of the fixing plate.
[0007] Preferably, a groove structure is provided in the fixing seat, and the interior of the groove structure is a semi-spherical structure.
[0008] Preferably, an inner ring is provided in the middle of the fixing plate, convex strips are evenly distributed on the inner ring, and one side of the convex strips is fixedly connected to the side surface of the fixing plate.
