Tobee® Slurry Pump Shaft Sleeve D075C21 is a quick - wear part of 6x4D-AH Slurry Pumps, and it is also used for 4x3D-AH Slurry Pump. The slurry pump shaft sleeve protects pump shaft from abrasion and corrosion within seal arrangements, Tobee offers different materials of shaft sleeve for international brand slurry pumps.
A shaft sleeve acts as a shield for the shaft assembly in pumps and compressors. A shaft sleeve is a hollow metal tube, cylindrical in shape, which is mounted over a shaft and shaft assembly to protect it in a corrosive environment. Shaft sleeves are commonly found in single-stage pumps. The pump shaft usually offers protection from corrosion and erosion. The basic function of a shaft sleeve is to protect the shaft from packing wear at the stuffing box. Shaft sleeves help protect the running surface of the shaft seal or the surfaces in contact from damage or abrasive wear. The hardness of the material used to construct the shaft must be sufficient; otherwise, it may cause a shaft sleeve to fail. The thermal expansion coefficient must be considered when designing a shaft sleeve. In ideal conditions, the shaft's coefficient of thermal expansion should be equal to that of the shaft sleeve.
