<p>MECHANICAL SEAL WITH IMPROVED FACE RING MOUNTING A mechanical seal construction having an annular face ring, preferably of hard material such as tungsten or silicon carbide, interference fitted within an annular flange formed on a seal ring. One of the face and seal rings is undercut so that the effective holding force between the flange and the face ring, as created by the interference fit, acts effectively only at, or at least adjacent, the central transverse plane of the face ring to substantially prevent distortion of the face ring. The inner end face of the face ring is axially spaced from the opposed end face on the seal ring, so that the face ring is supported on and engaged with the seal ring solely by the engagement therebetween substantially along the central transverse plane.</p> |
