Abstract: The invention relates to a mechanical seal assembly (1) for sealing between a high-pressure region (8) and a low-pressure region (9) on a rotating component (7), comprising a mechanical seal (2) with a rotating slide ring (3) with a first slide surface (30) and a stationary slide ring (4) with a second slide surface (40), wherein a sealing gap (5) is defined between the slide surfaces (30, 40), a slide ring carrier (31) for the rotating slide ring (3), which is configured to connect the rotating slide ring (3) to the rotating component (7) in a rotationally fixed manner, wherein the slide ring carrier (31) comprises a sleeve region (32), and a force support arrangement (6), which is configured to support an axial force (F) acting on the mechanical seal assembly (1), wherein the force support arrangement (6) is arranged on an end face (32a) of the sleeve region (32) of the slide ring carrier (31), wherein the force support arrangement (6) comprises a clamping sleeve (60), a conical sleeve (61) and a split ring

Abstract: The invention relates to a mechanical seal assembly comprising a mechanical seal (2) comprising a rotating mechanical seal (20) and a stationary mechanical seal (21) defining a sealing gap (22) therebetween, and a one-piece safety seal (3) provided as a redundant seal in the event of failure of the mechanical seal (2) and adapted to seal at a rotating component, the safety seal (3) comprising a base body (30) and a sealing area (31) projecting from the base body (30) in the axial direction (X-X) and being flexible, a thickness of the sealing area (31) in the radial direction being smaller than a thickness of the base body (30) in the radial direction, and the safety seal (3) being arranged in a stationary manner and comprising a sealing surface (32) on an inner circumference.
