The invention relates to a mechanical seal arrangement comprising a first mechanical seal () having a first rotating sliding ring () and a first stationary sliding ring () defining a first sealing gap () therebetween, a second mechanical seal () having a second rotating sliding ring () and a second stationary sliding ring () defining a second sealing gap () therebetween, a housing () having an inlet () and an outlet () for a cooling liquid, a rotating conveying sleeve () joined to the first rotating sliding ring () and the second rotating sliding ring (), the conveying sleeve () having a plurality of conveying grooves () on its outer circumference wherein the first stationary sliding ring () is arranged radially outside the conveying sleeve () and has an inner circumference () which is arranged eccentrically with respect to an outer circumference () of the conveying sleeve () so that a circumferential eccentric gap () is formed between the outer circumference () of the conveying sleeve () and the inner circumference () of the first stationary sliding ring () and wherein the first stationary sliding ring (), on a rear side () facing away from the first sealing gap (), has a first slot () directed towards the outlet () and a first widening recess () on the inner circumference (), which recess opens into the first slot ().

Mechanical seal arrangement with improved cooling characteristics

The invention relates to a mechanical seal arrangement for sealing on a rotating component (), comprising a slide ring seal () having a rotating slide ring () and a stationary slide ring (), which define a sealing gap () between the sliding surfaces () thereof, a recirculation conveyor () arranged adjacent to the rotating slide ring () wherein the recirculation conveyor () comprises a recirculation line () in which a cooling device () for cooling the recirculated fluid is arranged, a recirculation rotor () and a hollow cylindrical housing (), wherein the recirculation line () leads to a cavity () in the region of the sealing gap () of the sliding ring seal (), wherein the hollow cylindrical housing () comprises an inner shell surface () and an outer shell surface () and wherein a conveyor channel () is provided on the outer shell surface (), which conveyor channel () is formed along the outer shell surface () from a start portion () to an end portion () wherein the start portion () of the conveyor channel () is separated from the end portion () by a separating web (), wherein a plurality of feed openings () are provided in the hollow cylindrical housing (), which open from the inner shell surface () into the conveyor channel (), and wherein a single outlet opening () is provided at the end portion ().

Mechanical face seal assembly, in particular for hot media, and pump assembly

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.
