Abstract
A split face seal that provides fluid sealing between a housing and a rotating shaft includes first and second seal rings each having at least two seal ring segments and a radially extending seal face. The seal ring faces of the seal rings are opposed to one another. One of the seal rings is connected to the rotating shaft to rotate therewith, while the other seal ring is connected to the housing. The split seal also includes a mechanism for introducing a fluid to the seal faces of the first and second seal rings and a split support member having at least two support segments for radially supporting the first seal ring to inhibit radial separation of the seal ring segments of the first seal ring.
