Abstract: The invention relates to a mechanical seal arrangement comprising a rotating slide ring (2) and a stationary slide ring (3) which define a sealing gap (4) between them, a holding ring (5) for holding the stationary slide ring (3), and a housing (6), a clamp connection (7) being provided between the housing (6) and the holding ring (5) by way of at least one clamp component (8).

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.

Abstract: The present invention relates to a mechanical seal arrangement comprising: a mechanical seal (2) having a rotating slide ring (3) and a stationary slide ring (4) which define a sealing gap (5) therebetween, and a housing component (6) having an inner peripheral region (60), wherein the housing component (6) includes an outlet opening (7) for discharging a fluid, guided to the slide rings, and an inflow region, and wherein the inflow region comprises at least one transition channel (8; 9) which extends in the circumferential direction, becomes continually deeper towards the outlet opening (7), is formed in the housing component (6) and opens at the outlet opening (7).

Abstract: The invention relates to a mechanical seal arrangement, comprising at least one first mechanical seal having a rotating slide ring (2) and a stationary slide ring (3) which define a sealing gap (4) therebetween, a one-piece shaft bushing (5), an entrainment element (6) for transmitting a rotation of the shaft bushing (5) to the rotating slide ring (2), and at least one feather key (7) which is arranged between the shaft bushing (5) and the entrainment element (6) in order to permit torque transmission between the shaft bushing (5) and the entrainment element (6), wherein the feather key (7) comprises a base region (71) and an upper end region (72), and wherein the upper end region (72) is formed in an arcuate manner.
