ABSTRACT:
A unitary structure comprising a mechanical seal for rotating shafts consisting of a single ring member. The ring member has at one end a series of radial grooves in the internal bore and a trough extending across the grooves to an end of the ring. The ring also has at a second end at least one external labyrinth groove extending radially and serving to inhibit contamination. A sloped collection chamber having an expulsion port lies between the inner radial grooves and the external labyrinth groove. A non-metallic, flexible rotor is fitted within the sloped collection chamber whereby free flow across the axial width of the collection chamber is arrested and fluids are directed outwardly towards said expulsion port.
