Abstract

A mechanical seal and rotating agitator shaft assembly for effecting sealing between the shaft and the wall of the opening through which it extends into a mixer tank includes a sleeve dimensioned for removable mounting on the shaft and serving as a support for the rotating seal assembly which includes a sealing ring arranged for sealing against a glass coated portion of the shaft to prevent access of the contents of the tank to any metal part of the seal and shaft assembly. In the preferred embodiment, the shaft includes a glass coated boss located below the sleeve for engagement by the sealing ring.
