Abstract:

A device having a rotary shaft extending through a housing, with the device including a shaft seal for affecting a substantially fluid tight seal between the shaft and the housing, wherein the shaft seal includes: a rotating seal member secured to and rotatable with the shaft, a stationary seal member for affecting sealing contact with the rotating seal member, and wherein the rotating seal member is adjustably mounted on the shaft.
