ABSTRACT:
A rotary mechanical seal for a rotating shaft passing into a pressure vessel, the seal having stationary and rotating seal rings (12) with at least one of the rings (12) supported in an axially biased holder (9), characterized by an elastomeric annular seal (11) held in a groove, which groove is so designed as to obviate clogging or crystallizing in the gap between the seal face holder (9) and the housing (10). the groove has a protrusion located on its outer edge which has sloped inner and outer faces to cooperate with the annular elastomeric seal (11) so that the seal protrudes past or is flush with the edge.
