摘要： The invention relates to a mechanical seal assembly comprising a mechanical seal (2) with a rotating slide ring (3) and a stationary slide ring (4) defining a seal gap (5) therebetween, a pretensioning device (6) which biases the stationary slide ring (4) in the axial direction (X-X) of the slide ring seal arrangement, a support ring (7) which is arranged on the stationary slide ring (4), the support ring (7) being axially movable relative to the stationary slide ring (4) the pretensioning device (6) being arranged between the support ring (7) and the stationary slide ring, a fixing device (8) which is arranged for axially movable fixing the support ring (7) to a stationary component, a stop (9) which limits a distance (W1) by which the axially movable support ring (7) can be moved, and a secondary seal (10) which is arranged to seal between the support ring (7) and the stationary component.
