High temperature dynamic seal

A method of providing a seal between a housing and a rotating shaft, the method comprising:

• positioning a stationary ring within the housing, around the rotating shaft;
• coupling a seal ring carrier with the stationary ring, around the rotating shaft, with at least one arm member integrally formed with the seal ring carrier that extends into an anti-rotation cavity formed in the stationary ring, whereby rotational movement of the seal ring carrier is substantially limited;
• coupling a seal ring with the seal ring carrier, around the rotating shaft;
• positioning a biasing member adjacent the seal ring carrier, within a recess defined at least partially by a face of the stationary ring and the seal ring carrier, wherein said biasing member provides a seal between the seal ring and the stationary ring;
• securing an inner rotating ring with a surface of the rotating shaft exterior of the housing and closely adjacent the seal ring and stationary ring member, whereby a surface of the seal ring contacts a sealing face of the inner rotating ring;
• and
• securing an end portion of an outer rotating ring with an end portion of the inner rotating ring.

A seal assembly for use with rotating equipment that includes a housing and a rotating shaft, the seal assembly comprising:

• a stationary ring coupled with the housing and including an anti-rotation cavity formed therein, wherein the rotating shaft passes through the stationary ring;
• a rotating ring assembly secured about a portion of the rotating shaft exterior of the housing and closely adjacent the stationary ring, wherein the rotating ring assembly includes an inner rotating ring and an outer rotating ring that are operatively secured with one another;
• a seal ring carrier, positioned between the stationary ring and the rotating ring assembly, the seal ring carrier including at least one arm member integrally formed therewith and extending into the anti-rotation cavity, whereby rotational movement of the carrier is substantially limited;
• a seal ring coupled with the seal ring carrier between the stationary ring and the rotating ring assembly, wherein the seal ring contacts the inner rotating ring;
• and
• a biasing member positioned adjacent the seal ring carrier, within a recess defined at least partially by a face of the stationary ring and one or more arm members of the seal ring carrier, wherein the biasing member is operative to provide a seal between the seal ring carrier and the stationary ring.
