ABSTRACT:
A totally split mechanical face seal being installable and replaceable without necessitating breakdown of the shaft and/or housing. The inventive split seal is well suited for replacement of packing or stuffing in heavy duty or inaccessible locations. The inventive seals include a sealing element that seals the primary ring against the shaft and rigidly positions the primary ring in the axial, circumferential and radial directions, and also includes a sealing element which seals the mating ring against the housing and non-rigidly positions the mating ring in the axial diection while simultaneously providing an axial biasing force on the mating ring to provide mating contact of the two rings.
