Abstract: A mechanical seal has an axially floating seal face (21) in sliding contact with an axially stationary seal face (22). A biasing means (33), such as a magnet, biases the floating seal face towards the stationary seal face. The axially floating seal face and the biasing means are rotationally fixed relative to each other and the axially stationary seal face is free to rotate relative to the axially floating seal face. The seal may be used, for instance, as a bearing protector or isolator.

Abstract: A rotary seal has a floating seal face (21), in sealing relationship with a stationary seal face (22) and a fluid collection cavity (52, 34) adjacent the seal faces. The seal includes means (15) for introducing a lubricant into the vicinity of the cavity and means (19) for promoting the coalescence of the lubricant so that the lubricant accumulates in the cavity and lubricates the seal faces.

Abstract: A mechanical seal incorporates a metal bellows arrangement (1) which has a bellows unit (3) located between first and second end rings (5 and 7). The first end ring carries a seal face (9) and the second end ring is attached to a further seal component (11). The second end ring is associated with a sealing ring (17, 19) which is located between the second end ring and the other seal component. The second end ring is shaped to accommodate the sealing ring in a plurality of different cross-sectional shapes.

Abstract: An isolator seal comprises a stator member (17) for location into the stator of rotating equipment and a rotor member (14) for location onto a rotary shaft of the rotating equipment. These two members provide respective adjacent surfaces (82/83) and a static shut-off device (81) engages both adjacent surfaces when the rotor member is static and disengages one or more of said surfaces when the rotor member is dynamic. In one aspect of the present invention at least one of said surfaces is inclined to the longitudinal axis at an angle greater or less than 90°. In a further aspect of the present invention the static shut-off device comprises a resilient annular sealing member (354) and an auxiliary member (357), movable between a first position, when the rotor member is static, at which said auxiliary member compresses said resilient annular member into engagement with both said surfaces, and a second position at which the compression on said resilient member is reduced, whereby the resilient annular member disengages one or more of said rotor and stator surfaces when the-rotor is dynamic.
