A rotary face seal with magnetic loading which sealingly couples a shaft to a housing, comprising: a stationary housing having a seat; a cup, having an inwardly facing groove and a central bore, residing the housing; a shaft located in the bore; a seal case residing between the cup and the shaft; an O-ring residing in the inwardly facing groove of the cup to sealingly interface the cup with the seal case providing a secondary seal and allowing axial movement of the seal case within and relative to the cup; a retaining ring connecting the cup to the seal case thereby preventing the seal case from becoming disengaged from the cup; a seal ring in communication with the seal case;a rotating mating ring, having a seal face in communication with the seal ring; the rotating mating ring rotating with the shaft; and wherein a magnetic band is connected to the rotating mating ring; the magnetic band and the seal case being magnetically attracted to and pulled toward each other thereby providing a mechanical puller load assembly in the rotating mating ring thereby urging the seal case toward the rotating mating ring and the seal ring into sealing communication with the seal face of the rotating mating ring, wherein the magnetized band is tubular shaped, axially oriented, and magnetized with a single pole adjacent to the seal case, and wherein the seal ring maintains an air gap, in an axial direction, between the seal case and the magnetized band; wherein the mechanical load puller assembly is a magnetic band residing in a circumferential notch in the rotating mating ring; and wherein the seal face of the rotating mating ring further includes a plurality of hydrodynamic grooves. a stationary housing having a seat; a cup, having an inwardly facing groove and a central bore, residing the housing; a shaft located in the bore; a seal case residing between the cup and the shaft; an O-ring residing in the inwardly facing groove of the cup to sealingly interface the cup with the seal case providing a secondary seal and allowing axial movement of the seal case within and relative to the cup; a retaining ring connecting the cup to the seal case thereby preventing the seal case from becoming disengaged from the cup; a seal ring in communication with the seal case;a rotating mating ring, having a seal face in communication with the seal ring; the rotating mating ring rotating with the shaft; and wherein a magnetic band is connected to the rotating mating ring; the magnetic band and the seal case being magnetically attracted to and pulled toward each other thereby providing a mechanical puller load assembly in the rotating mating ring thereby urging the seal case toward the rotating mating ring and the seal ring into sealing communication with the seal face of the rotating mating ring, wherein the magnetized band is tubular shaped, axially oriented, and magnetized with a single pole adjacent to the seal case, and wherein the seal ring maintains an air gap, in an axial direction, between the seal case and the magnetized band; wherein the mechanical load puller assembly is a magnetic band residing in a circumferential notch in the rotating mating ring; and wherein the seal face of the rotating mating ring further includes a plurality of hydrodynamic grooves.
