ABSTRACT:
A shaft seal of the mechanical face seal type split along a diametric plane thereof and which therefore can be installed relative to a shaft without disassembly of attendant equipment. The stationary and rotating components of the seal each may have the half elements thereof assembled in corresponding half elements of an attendant split annular holder and the holder half elements then may be engaged about the attendant shaft and be secured together. Thereafter, the assembled holders may be relatively axially shifted along the shaft toward engagement with each other and mounted in operative association with each other within a diametrically split gland housing, all of which relative assembly of the split stationary and rotating seal components in the corresponding split holder, assembly of the holders about the shaft and assembly of the assembled holders within the gland housing halves may be carried out by a single person, even within a crowded work area.
