ABSTRACT:
A mechanical face seal comprises a first seal face member associated in fixed relationship and sealed with respect to one component, a second seal face member associated in fixed rotational relationship and sealed with respect to a second component and a third seal face member interposed between the first and second seal face members. Springs are provided to urge the second seal face member towards the first seal face member and maintain the first, second and third seal face members in sealing engagement. The sealing faces of the first, second and third seal face members are inclined, so that the first and second seal face members impose a radial load on the third seal face member. Two such seal assemblies may be provided co-axially of one another to provide a double seal.
