A machine has: an outer member; an inner member having an outer diameter (OD) surface; and a seal system. A seal housing is mounted to the outer member and has first and second walls; a first seal stage contacting the OD surface and the first wall; a second seal stage contacting the OD surface and the second wall; and a wave spring biasing the seal stages axially apart from each other. The seal stages each have a plurality of seal segments interfitting end to end and each having: a first end; a second end circumferentially opposite the first end; a first face; a second face axially opposite the first face; an inner diameter (ID) face; and an outer diameter (OD) face having a radially protruding lug. The housing has an inner diameter (ID) surface having recesses receiving the lugs of the seal stages to circumferentially retain the seal stages.
