ABSTRACT:
To achieve increased critical speeds in turbines, pumps and other machines by limiting overhang while eliminating secondary sealing components, a face seal is provided for a rotatable shaft. The face seal includes an annular sealing ring formed of a rigid material and having a sealing surface adapted to be disposed in a plane substantially transverse to the rotatable shaft. The face seal also includes a static seal-carrying member formed of a rigid material and spaced from the annular sealing ring at a location remote from the sealing surface. Additionally, an elastomeric seal is disposed between the annular sealing ring and the static seal-carrying member in integrally associated relation.
