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

The invention relates to a mechanical seal arrangement comprising: a rotating slide ring () having a first slide surface and a stationary slide ring () with a second slide surface which between them define a sealing gap, wherein the first and second slide surfaces have different hardnesses, wherein the harder slide surface has a diamond coating () and the softer slide surface is produced from carbon composite material, and wherein an average initial roughness R(of the diamond coating) is less than an average initial roughness Rof the slide surface made from carbon composite material.
