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.

Abstract: A composite seal assembly (10) for providing a seal between a rotating shaft (18) and a static surface (58). The composite seal assembly includes first (12) and second (14) axially adjacent annular seal elements. The first and second seal elements each include a sealing edge (62 and 64) contacting the shaft to provide a respective seal between the first and second seal element and the shaft. A static housing (23) receives the first and second seal elements and engages the static surface to provide a static stationary seal, while concomitantly providing a flex region (386) that engages the seal elements to form a dynamic seal therewith.
