摘要： A non-contacting rotary face seal assembly includes a first sealing member, including a first sealing face and a first magnetic element; and a second sealing member, including a second sealing face and a second magnetic element. The first and second magnetic elements of the first and second sealing members provide a magnetic repulsion force between the first and second magnetic elements such that the magnetic repulsion force separates the first and second sealing faces before hydrodynamic or hydrostatic forces associated with rotation of the second sealing member become sufficient to prevent the first and second sealing faces from contacting.
