Abstract: A seal support system for a mechanical seal includes a system vessel for containing barrier fluid. Closed loop pipe work connects the vessel to a mechanical seal with a device provided for feeding barrier fluid to the system vessel. A further vessel is provided that is able to be in fluid communication with the system vessel. The further vessel may be provided with an elastomeric membrane, which may be filled with a gas under pressure to an extent required to allow for the effect of the highest anticipated temperature which might occur in a particular application.

Abstract: An isolator seal includes a stator member for placement into the stator of rotating equipment and a rotor member for placement onto a rotary shaft of the rotating equipment. The stator member and the rotor member provide respective adjacent surfaces, while a static shut-off device engages both adjacent surfaces when the rotor member is static and disengages one or more of the surfaces when the rotor member is dynamic. In one embodiment of the invention at least one of the surfaces is inclined to the longitudinal axis at an angle greater or less than 90°. In a further embodiment, the static shut-off device includes a resilient annular sealing member and an auxiliary member, which can move between a first position, when the rotor member is static, at which the auxiliary member compresses the resilient annular member into engagement with both surfaces, and a second position at which the compression on the resilient member is reduced, so that the resilient annular member disengages one or more of the rotor and stator surfaces when the rotor is dynamic.

Abstract: A gas seal assembly includes a pair of mutually rotatable sealing members, each of which has a front face adjacent a gap between the two members which constitutes a leakage path through the seal assembly. The two sealing member are urged, in use, in a direction to close the gap and a gas bleed arrangement is provided for allowing gas from a high pressure side of the seal to bleed into the gap so as to apply a force tending to separate the members. The gas bleed arrangement includes a bore extending between the front face and a rear face of one of the sealing members, a generally radial groove formed in the rear face of the sealing member and a plate overlying the rear face to cover the groove and thereby define between the rear face of the sealing member and the plate a bleed passage connecting the bore to the high pressure side of the seal. The plate is formed as a shim that is sufficiently flexible to be deflected by the gas pressure into mating contact with the rear face of the sealing member so as to confine the gas flow of the bleed passage to the radial groove.
