Patent number: 10955054Abstract: 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 (F1) on the piston element of the first piston arrangement.Type: GrantFiled: April 18, 2017Date of Patent: March 23, 2021Assignee: EagleBurgmann Germany GmbH & Co.

Patent number: 6616145Abstract: A face seal device for use with components rotating at a high rotational speed includes a non-rotating face seal ring (5) and a rotary face seal ring (11) mounted in a loose fit on and rotatable together with the rotary component. The rotary face seal ring includes a sealing face (6) which, in operation, is essentially radially aligned for cooperation with an opposite sealing face (16) of the non-rotating face seal ring. The rotary face seal ring is formed of at least a base portion (20) and an extension portion (21). The extension portion provides an additional mass and has an areal center of gravity axially spaced from the areal center of gravity of the base portion An axial spacing z between the areal centers of gravity and the mass m of the extension portion are in specific relationship with each other, whereby in operation a torque directed towards the non-rotating face seal ring is applied to the rotary face seal ring.Type: GrantFiled: November 23, 2001Date of Patent: September 9, 2003Assignee: Burgmann Dichtungswerke GmbH & Co.
