A mechanical face seal which includes a non-rotatable seal ring and a rotatable mating ring biased into rubbing engagement. The non-rotatable seal ring is disposed in a stationary housing and is axially biased toward the rotatable mating ring which is fixed to a rotatable shaft. An anti-rotation member is pressed into the housing and is engageable with the non-rotatable seal ring to prevent its rotation while allowing axial movement thereof. |
