ABSTRACT:
A seal device, which accommodates axial displacement between a housing and shaft of an item of rotating equipment, includes a stator which locates into the housing of a piece of rotating equipment. A first rotor locates on the shaft of the rotating equipment and a second rotor is rotationally coupled to the first rotor with the first rotor being permitted to axially float with respect to the second rotor. The device provides sealing integrity when the shaft is both idle and operational. The sealing device may be used, for instance, in a double ended centrifugal pump where shaft displacement occurs from thermal expansion.
