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 contacting seal device provides a seal between equipment housing and an equipment shaft. The contacting seal device includes a stator that can be sealed to the equipment housing by a first torroidal sealing member, a first rotor that can be sealed to the equipment shaft by a second torroidal sealing member and a second rotor mounted for longitudinal movement relative to the first rotor and sealed to the first rotor by a third torroidal sealing member. The stator and the second rotor each have contact faces and one or more biasing devices urge the contact face of the second rotor into engagement with the contract face of the stator.

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°.

Abstract: An isolator device, which may be a bearing seal or a bearing isolator, for use hindering fluid flow between components which are rotating relative to each other about a longitudinal axis, the flow being in one direction parallel to this axis, includes a stator for securing to a rotary fixed one of the components and a rotor for securing to a relatively rotating one of the components. The stator has a surface which extends longitudinally and adjacent to a surface of a component, which rotates relative to the stator. The fluid flow is between the two surfaces and the stator surface is non-parallel to the adjacent component surface and is shaped to promote fluid flow in a direction opposing the general fluid flow direction.

Abstract: An intelligent seal support management system includes a device for automatically compensating for increased heat or decreased heat in a vessel.

Abstract: A gland plate includes a rigid, disk-shaped element that includes at least one radially extending wall having a thickness of from about 0.1 to 4 mm.

Abstract: The present invention provides a modular gland member for use in a mechanical seal, wherein the gland member has a radially or axially extending cavity adjacent to a seal face, and the cavity includes a solid or fluid thermal conducting member to dissipate heat from the seal face into the surrounding components.

Abstract: A mechanical seal 10 provides a fluid tight seal between relatively rotatable elements such as a drive shaft and a housing. The seal includes first and second seal faces (13, 11) and transmission means (27) which engage said second seal face and extend axially therefrom in a direction away from said first seal face. Biasing means (28) bias the transmission means, and thereby the second seal face, towards the first seal face. Drive means (29) engage the transmission means and are for mounting in driving engagement with the second element. The drive means include at least one radially extending engagement portion (30) which extends into an axially enclosed opening (31) in the transmission means.

Abstract: A modular mechanical seal with a gland member, which is common to more than one generic seal format.

Abstract: A mechanical seal includes at least one self-aligning member and has the capability to modify fluid flow radially inwardly of the self aligning member. The fluid flow may be modified by one or more of cutwater or pumping vanes/grooves in an eccentric arrangement.

Abstract: A seal that provides sealing between a rotatable shaft and a housing has a stationary part for connection to the housing and a rotary part for rotation with the shaft. The rotary part includes a sleeve for mounting on the shaft. One end of the sleeve is provided with a non-elastometric sealing arrangement. The sealing arrangement has sealing surfaces for contacting outer circumferential surfaces of the sleeve and the shaft as well as means for effecting sealing engagement between each of said sleeve and said shaft and a respective sealing surface.

Abstract: A sealing device for rotating equipment includes one or more sensors and one or more data storage devices. The sensorw are arranged to receive variable information relating to the performance of the dealing device and to feed the information to the storage device or devices.
