The invention relates to a mechanical seal assembly comprising a mechanical seal with a rotating slide ring and a stationary slide ring, wherein one of the two slide rings has a first slide surface, wherein the other of the two slide rings has a second slide surface with a circumferentially closed sealing blade which protrudes from a bottom region of the second slide surface in the direction of the first slide surface by a height (H), wherein the sealing blade has a width (B) in a range of between 10 and 500 &#x3bc;m, wherein at least one pre-tensioning element braces the slide rings against each other, wherein the second slide surface and the sealing blade on the second slide surface have a diamond coating.

Mechanical seal arrangement with minimal leakage

The invention relates to a mechanical seal arrangement, comprising a rotating slide ring () and a stationary slide ring (), which define a sealing gap () in between them, and a bellows unit () with a bellows element () and an intermediate disc (), wherein the bellows element () has a first connector area (), a second connector area (), and a bellows intermediate area (), wherein the bellows element () is made of an elastomer material and provides a connection between the rotating slide ring () and a rotating structural component (), wherein the intermediate disc () is arranged between the bellows element () and the rotating slide ring (), and wherein the intermediate disc () has at least one slit () that has a slit width (B) that is smaller than a slit length (S), and wherein the slit () is closed at one side, so that a connection area () remains at the slit () at the intermediate disc ().

Mechanical seal arrangement with a bellows element

The invention relates to a mechanical seal arrangement, comprising a rotating slide ring and a stationary slide ring which define a sealing gap therebetween, and a bellows unit with a bellows element and an intermediate disk, wherein the bellows element has a first connection region, a second connection region and a bellows intermediate region, wherein the bellows element is produced from an elastomer material and provides a connection between the rotating slide ring and a rotating component, wherein the intermediate disk is arranged between the bellows element and the rotating slide ring, and wherein an inner peripheral region of the intermediate disk is arranged for support on the rotating component.

Mechanical seal arrangement having a bellows element

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.

Mechanical seal arrangement having sliding surfaces of different hardness

A seal ring for a mechanical seal, comprising a base body, a first layer applied to a first face side of a base body, and a second layer applied to a second face side of the base body. At least one of the layers is configured as a slide surface of the seal ring.
