Abstract (en)
[origin: WO8900247A1] 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), characterised by an elastomeric annular member (11) held in a groove, which groove is so designed as to obviate clogging or crystallising in the gap between the seal face holder (9) and the housing (10). Preferably, the groove has a protrusion located on its outer edge which has sloped inner and outer faces to co-operate with the annular elastomeric member (11) so that the member (11) protrudes past or is flush with the edge.
