Abstract

Split mechanical seal assemblies which include a pressurized fluid barrier and multiple concentric and axially aligned stationary seal rings. The stationary seal rings are in sealing relation with a rotary seal ring at their respective seal faces, and with the gland of the mechanical seal assembly, thereby forming an annular cavity for pressurized fluid to create a positive fluid pressure barrier across the seal faces when in sealing contact with each other.
The axially and concentrically aligned stationary seal rings comprise an inner stationary seal ring and an outer stationary seal ring, and the area of the axially extending portion of the outer surface of the outer seal ring partially defining the annular cavity is greater than the area of the axially extending portion of the inner surface of the outer seal ring partially defining the annular cavity. The split configuration of the seal assembly facilitates quick installation, removal and maintenance of the seal assembly and its component parts. The seal assembly is also compact in design on account of the concentric and axially aligned stationary seal rings, permitting installation and maintenance of the assembly and its component parts under circumstances where space is limited. These benefits are provided without sacrificing the function benefits of a pressurized fluid pressure barrier as a supplement to the seal between the stationary and rotary seal rings.
