A contacting seal device provides a seal between equipment housing (13) and an equipment shaft (12). The device Includes a stator (15) sealable to the equipment housing by a first toroidal sealing member (16), a first rotor (14) sealable to the equipment shaft by a second toroidal sealing member (17) and a second rotor (27) mounted for longitudinal movement relative to said first rotor and sealed to said first rotor by a third toroidal sealing member (28). The stator and the second rotor each have contact faces (50) and one or more biasing magnets urge the contact face of the second rotor into engagement with the contract face of the stator. |
