ABSTRACT:
The relatively rotatable sealing faces of mechanical seal are provided with circumferentially spaced pockets which provide a path of fluid flow across the sealing faces during rotation of the rotatable sealing ring but no path when there is no relative rotation therebetween. The fluid flow enhances the lubrication and cooling of the faces.
