Abstract: A loading mechanism (30) for a fluid seal (10) that allows an installer to change or adjust the axial bias applied to a stacked set of sealing elements (12). The loading mechanism includes a bolt-like adjusting element (66) that has a foot portion (80) attached to one end (74) and a rail element (32) that is threadingly coupled at an opposite end (72). By rotating the adjusting element, the rail element can travel axially along the adjusting element. The axial displacement of the rail element allows the installer to select the amount of axial force or bias applied by the loading mechanism to the sealing elements.

Abstract: A radial seal assembly for providing a seal between a shaft and a static surface includes a gland forming a housing for mounting the seal assembly to the stationary equipment, a sleeve mounted to an movable with a shaft extending from the stationary equipment and a sealing component housed between the gland and sleeve for sealing therebetween. The sealing component includes at least one axially forwarding extending seal surface and at least one axially rearward extending seal surface for providing sealing under both normal and reverse pressure conditions. The sleeve may include a tapered axially inner tip having a double lead-in angle to facilitate assembly while minimizing the length of the seal assembly.

Abstract: The present invention provides a rotary seal assembly (100) for providing sealing on a rotating shaft (502, 1002) or other suitable device. The seal assembly seals against a rotating shaft or other piece of moving equipment to prevent the leakage of fluids. In some embodiments, a split rotary seal assembly employing an energizer (120), housing (130), and a rotational seal element such as a matrix (110) is provided. The energizer energizes the matrix to enhance the sealing properties of the assembly. Furthermore, the matrix conforms to the surface of the shaft, and moves radially with the shaft to provide an effective seal in high wear or runout applications.

Abstract: A mechanical composite seal assembly for providing a seal between a rotating shaft and a static surface. The mechanical composite seal assembly includes first and second axially adjacent annular seal elements. The first and second seal elements each include a sealing edge contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region that engages the seal elements to form a dynamic seal therewith.

Abstract: A split labyrinth seal assembly having split stationary and rotary sealing elements, and a split clamping mechanism. The clamping mechanism is configured to secure the rotary element to a rotating shaft. The rotary element can also include an integrally formed valve element that moves between a contacting and a non-contacting position in response to rotation of the shaft. The rotary element and the clamping mechanism can have surface features associated therewith to promote nesting between the components.
