The use of standard magnetic couplings in hermetically sealed machines with high pressure inside the working cavity is considered. It is shown that in this case it is also necessary to increase the air gap between the semi-coupling. The transfer torque of the coupling may be maintained by increasing the axial length of the permanent high-coercive magnets and through the use of stronger magnets or by increasing the outer diameter across the magnets of the inner semi-coupling.
