A mechanical face seal includes a rotating counter ring having a sealing surface and two radial planes. Each of the radial planes is associated with a clamping cam. A stationary face seal ring has a sealing surface opposite from the sealing surface of the counter ring. The sealing surfaces of the counter ring and the face seal ring bear against each other.

Mechanical face seal with a rotating counter ring and precisely defined clamping

A mechanical face seal includes a rotating counter ring having a sealing surface and a stationary face seal ring having a sealing surface. The sealing surface of the counter ring is disposed opposite from the sealing surface of the face seal ring. The sealing surfaces of the counter ring and the face seal ring bear against each other.

Mechanical face seal

A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring ( ) and a rotary face seal ring ( ). The rotary face seal ring is mounted in a loose fit for common rotation with a rotating component and includes a sealing face ( ) which, in operation, is essentially radially aligned for cooperation with an opposite sealing face ( ) of the non-rotating face seal ring. A heavy-mass-contributing element ( ) is arranged to rotate in common with the rotating component and engages a portion of the rotary face seal ring. The center of gravity of the heavy-mass-contributing element is axially spaced from that of the rotary face seal ring, whereby, in operation, a torque directed towards the non-rotating face seal ring is applied to the rotary face seal ring. This torque arises from the centrifugal forces that correspond to the mass-contributing element and the spacing between the centers of gravity.
