A split mechanical 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 continuous, circumferential groove formed in the seal face of the first seal ring for introducing a fluid to the seal faces of the first and second seal rings to establish a seal therebetween. A split support member having at least two support segments for coupling the first seal ring to the housing or the rotating shaft is also provided. The split face seal is operable as both a contacting and a non-contacting mechanical face seal.

Split mechanical face seal

A split mechanical face seat 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 surface. The seal ring surfaces 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 surfaces of the first and second seal rings. The seal further is provided with a system for fluidly retaining together the seal ring segments of one of the seal rings in a sealing relationship during a negative pressure condition.

Split mechanical face seal with negative pressure control system

A split mechanical 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 surface. The seal ring surfaces 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 surfaces of the first and second seal rings. The seal further is provided with a system for maintaining co-planar alignment of the seal faces.

Split mechanical face seal with resilient pivoting member

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.
