The present invention relates to a mechanical seal arrangement, comprising a rotating slide ring and a stationary slide ring, which define a sealing gap between them, and a delivery device for delivering a fluid, wherein the delivery device comprises a sleeve-like basic body with first through-openings and second through-openings, wherein the delivery device rotates jointly with the rotating slide ring, wherein the first through-openings each have a first entry region on an outer periphery of the sleeve-like basic body and a first exit region on an inner periphery of the sleeve-like basic body, and wherein the second through-openings each have a second entry region on the inner periphery of the sleeve-like basic body and a second exit region on the outer periphery of the sleeve-like basic body.

Sliding ring seal with conveying sleeve

The present invention refers to a seal ring for a mechanical seal, comprising: a base body () with a diamond layer () which is applied to the base body () and configured as a sliding surface, wherein the diamond layer () has a thickness (D) which is less than or equal to 4 &#x3bc;m, particularly less than or equal to 3 &#x3bc;m, particularly less than or equal to 2 &#x3bc;m, particularly preferably about 1 &#x3bc;m, and wherein the base body () is without fissures or only comprises fissures that have a maximum longitudinal extension (L) on a surface of the base body () or in the base body () that is less than or equal to 5 &#x3bc;m.

Low-friction seal ring with inexpensive diamond coating

A seal arrangement for sealing a shaft with respect to a housing containing a fluid comprises a face seal exposed to a buffer gas on a portion thereof facing away from the fluid. Disposed upstream of the face seal at the fluid said portion thereof is a collecting chamber for receiving a leakage of the buffer gas having gained access to the fluid-side portion of the face seal. The collecting chamber is in communication with an external separating means for separating the gas phase from the fluid phase of a gas/fluid mixture having collected in the collecting chamber. The fluid phase can be returned into the interior of the housing.
