A mechanical seal arrangement includes a first mechanical seal with a rotating slide ring and a stationary slide ring, which define a sealing gap in between them. The mechanical seal arrangement includes a first sealing space that is filled with a sealing liquid. The first mechanical seal seals off the sealing space against a surrounding area, a first piston arrangement with a piston element and flexible wall areas that define a first piston interior space, wherein the first piston interior space is in fluid connection with the first sealing space. A piston outer surface of the piston element is in fluid connection with the surrounding area, and a first pre-stressing appliance that exerts a first preload force (F) on the piston element of the first piston arrangement.

Mechanical seal arrangement and well bore conveyor device

The invention relates to a mechanical seal arrangement, comprising a rotating slide ring () and an stationary slide ring (), which delimit a sealing gap () in between them, wherein the rotating slide ring () has a radially inward facing ledge () with a contact surface (), a bellows element () for refitting the rotating slide ring () in an axial direction (X-X) of the mechanical seal arrangement, and a release protection device () for the rotating slide ring (), wherein the release protection device () comprises an inner sleeve () with a radially outward facing web () that restricts a movement of the rotating slide ring () in the axial direction (X-X), and wherein the rotating slide ring () is arranged on the inner sleeve () so as to be freely movable in the axial direction (X-X).
