ABSTRACT:
A mechanical seal apparatus for use between a wall and a shaft extending through an opening in said wall with relative rotation occurring therebetween. The shaft extends from a first region at a first pressure into the opening in the wall and a second region at a second pressure. A seal element is positioned within the opening and has mutually contacting sealing faces. One annular seal member is fixed with respect to the wall and another annular seal member is fixed with respect to the shaft. The annular seal member is oriented at an exterior portion of the wall and has an outer diameter less than the diameter of the opening in the wall to define a gap therebetween. A bushing member is snugly received in the gap for preventing entry and collection of material into the gap. The bushing member has an axially facing surface facing away from said opening as well as radially outwardly of said shaft for repelling the material from entry into the gap.
