Abstract
A clamshell half of a split ring mechanical seal face assembly comprises a split seal ring half having circumferential and proximal surfaces that are seated against corresponding radial and axial support surfaces of a holder half. At least one extending member extends from a hole in the proximal surface to an arcuate slot in the axial support surface, or vice-versa, and thereby radially constrains the split seal ring half to remain unitized with the holder half during clamshell assembly, while permitting rotation of the split seal ring half about a shaft axis over a limited range, which in embodiments is between 2 degrees and 20 degrees. Embodiments further include a secondary seal between the holder half and split seal ring half that frictionally resists displacement of the split seal ring half.
