Abstract

The invention relates to a rotating mechanical seal arrangement (1) for sealing a product side (5) at a rotating component, comprising a first rotating mechanical seal (2) with a first rotating slide ring (21) and a first stationary slide ring (22) which define a first sealing gap (23) between them, a second rotating mechanical seal (3) with a second rotating slide ring (31) and a second stationary slide ring (32) which define a second sealing gap (33) between them, a fluid space (4) which is limited by the first and second rotating mechanical seals (2, 3), wherein the first rotating mechanical seal (2) is lubricated with a product medium of the product side (5), and wherein the second rotating mechanical seal (3) is lubricated with a liquid quench medium of a quench supply unit (7), the quench medium being located in the fluid space (4), a quench outlet (8) via which quench medium may be discharged from the fluid space (4), a gas outlet (9) via which a gas located in the fluid space may be discharged, and a throttle device (10) which is arranged in the fluid space (4) between the first rotating mechanical seal (2) and the second rotating mechanical seal (3) and divides the fluid s…
