Abstract:
An axial face seal arrangement, which is arranged for joint rotation with a drive shaft in a rotary machine, includes a base element and a moving part, wherein the base element is connectable to a drive shaft for joint movement therewith, the moving part presenting a sealing end face and being axially movable in relation to the base element and biased from the base element by a spring, wherein the moving part and the base element include at least one torque driver pin and at least one corresponding aperture into which the torque driver pin is displacably inserted for joint rotational movement of the moving part with the base element. At least one wear protection pin is arranged between the torque driver pin and the aperture at a force transmitting interface of the torque driver pin and the aperture.
