ABSTRACT:
A rotary mechanical face seal includes first and second seal face members, the sealing face of one seal face member being urged into engagement with the sealing face of the other seal face member, said seal face members being such that when subjected to temperature gradients due to the generation of heat at the sealing faces, the sealing faces will remain substantially parallel in spite of any thermal distortion of the seal face members.
