ABSTRACT:
A seal assembly for sealing a volatile liquid from escaping past a rotating shaft mounted within a housing, includes a rotating sealing ring having a seal facing keyed to the shaft and a stationary sealing ring having a seal facing mounted to the housing. The seal facing of the stationary sealing ring is in contact with the sealing facing of the sealing ring keyed to the shaft when the shaft is non-rotating. When the sealing ring is rotated by the shaft the seal faces are disengaged from one another. One of the seal facings of either the rotating or stationary sealing ring includes a plurality of notches positioned on the outer radial edge of the sealing surface at an angle of approximately 45.degree. with respect to the perpendicular peripheral surface of the sealing ring.
