1) Description of Shaft Sleeve
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.
2) Function of Shaft Sleeve
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.
