Abstract:
1. A seal arrangement comprising: a mechanical seal comprised of a stationary annular counter member and a slide ring that is fixedly connected to a rotating machine part to be sealed by the seal arrangement; wherein the annular counter member has a first radial end face and the slide ring has a second radial end face that faces the first radial end face; wherein the first and second radial end faces form sliding surfaces that are forced by a pressing force to rest flat against one another and define a sealing gap extending in a radial plane; a sealing ring surrounding externally the annular counter member and resting seal-tightly against an inner wall of a mounting space of the seal arrangement; a support disk that is disposed in the mounting space of the seal arrangement and secures axially the annular counter member in the mounting space; at least one sealing lip directly connected to the support disk, wherein the at least one sealing lip is arranged downstream of the sealing gap on a side of the sealing gap where the annular counter member is located; wherein the at least one sealing lip is disposed on a face of the support disk that is facing the annular counter member, wherein the at least one sealing lip projects away from the face into a recess of the annular counter member and rests against the rotating machine part within the recess; wherein the at least one sealing lip provides a sealing action during initial running-in of the sliding surfaces of the annular counter member and the slide ring.
