1. A fluid processing machine configured to operate on a process fluid, the fluid processing machine comprising:
a frame configured to structurally support at least a portion of the fluid processing machine;
a shaft configured to operatively rotate about an axis and relative to the frame, the shaft comprising a projection in a radial direction relative to the axis;
a sealing armature configured to contact the projection, wherein the sealing armature comprises an axial degree of freedom relative to the axis;
a dynamic rotational seal between the projection and the sealing armature; and
a dynamic axial seal between the sealing armature and the frame, wherein the dynamic axial seal comprises one or more metallic seals and one or more elastomeric seals, wherein the one or more metallic seals are configured to seal between the sealing armature and the frame circumferentially about the axis and to protect the one or more elastomeric seals from pressure transients of the process fluid.
