Abstract

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.
