ABSTRACT:
A mechanical seal assembly including at least one pair of co-operating seal rings, one of which is provided for common rotation with a rotating component and the other of which is provided rotationally fixed at a stationary component. One of the seal rings is axially movable and axially biased with a biasing force against the other seal ring, the biasing force being transmittable through a force transmitting ring to the respective seal ring, in order to bias facing sliding surfaces of the seal rings, between which a sealing gap is formed during operation, in a mutual sealing engagement, and a secondary sealing assembly provided at the force transmitting ring for sealing the axially movable seal ring with respect to at least one circumferential guiding surface of a guiding component guiding the movement of the seal ring and the force transmitting ring.
