Abstract
The present invention provides a rotary seal assembly for providing sealing on a rotating shaft 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, housing, and a rotational seal element such as a matrix 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.
