The invention relates to a rotating mechanical seal arrangement () for sealing a product side () at a rotating component, comprising a first rotating mechanical seal () with a first rotating slide ring () and a first stationary slide ring () which define a first sealing gap () between them, a second rotating mechanical seal () with a second rotating slide ring () and a second stationary slide ring () which define a second sealing gap () between them, a fluid space () which is limited by the first and second rotating mechanical seals (), wherein the first rotating mechanical seal () is lubricated with a product medium of the product side (), and wherein the second rotating mechanical seal () is lubricated with a liquid quench medium of a quench supply unit (), the quench medium being located in the fluid space (), a quench outlet () via which quench medium may be discharged from the fluid space (), a gas outlet () via which a gas located in the fluid space may be discharged, and a throttle device () which is arranged in the fluid space () between the first rotating mechanical seal () and the second rotating mechanical seal () and divides the fluid space () into a product-side fluid space region () and an atmosphere-side fluid space (), wherein the gas outlet () is arranged at the product-side fluid space region () and the quench outlet () is arranged at the atmosphere-side fluid space region ().

Rotating mechanical seal arrangement with improved gas separation

A divided driver device () for a mechanical face seal for non-rotatable assembly on a rotary component and for the transmission of a torque to a seal ring () held in non-rotatable manner on the driver device. The driver device () is divided in at least a single radial plane so as to form sections in the form of segments of a circle that are adapted to be clamped together to form a ring shape and furthermore, it is axially sub-divided into a divided retaining ring () for retaining the seal ring () and a divided mounting ring () for non-rotatable mounting to the rotary component. The rings () are coupled together for rotation in common, as indicted by (). The retaining ring () comprises mutually sealed sections () in the form of segments of a circle which are adapted to be placed together to form a ring shape having an inner radial dimension that is greater than the nominal outer radial dimension of the rotary component concerned (), and said sections comprise peripherally aligned end faces () which are preferably in metal-to-metal contact with one another and have a surface finish for mutually sealing them.
