Claims19
A split mechanical face seal comprising:
- a pair of seal ring assemblies, each said ring assembly comprising a rigid seal ring of split ring segments and securing means extending about the outer circumference of each said ring holding said segments thereof together;
- said rings each having a flat radially extending sealing surface, the sealing surfaces of said rings being in sealing contact with each other;
- characterized in that
- said rings are axially non-rigidly supported in said seal by resilient support means resiliently contacting and supporting each said ring axially on a side opposite the sealing surface thereof;
- and
- at least one of said support means comprises biasing means axially biasing said rings and said sealing surfaces thereof together.
The split seal claimed in any one of the preceding claims further characterized in that said ring segments of each said ring comprise adjacent irregular mating split faces in mating contact with each other for accurately aligning the flat sealing surface thereof at said split faces.
