Abstract

An assembly is provided for rotational equipment with an axial centerline 22. This assembly includes a primary seal device 40, a ring structure 44 and a secondary seal device 42. The primary seal device 40 is configured as a hydrostatic non-contact seal device. The primary seal device 40 includes a plurality of seal shoes 54 and a seal base 52. The seal shoes 54 are arranged circumferentially about the axial centerline 22 in an annular array. The seal base 52 circumscribes the annular array of the seal shoes 54. The ring structure 44 is axially engaged with the seal base 52. The secondary seal device 42 is mounted with the ring structure 44. The secondary seal device 42 includes a seal ring body 90 and an alignment tab 104. The seal ring body 90 is configured to substantially seal an annular gap 30 between the ring structure and the seal base 52. The alignment tab 104 projects out from the seal ring body 90 and into an aperture 106 in the ring structure 44. The alignment tab 104 is adapted to substantially rotationally locate and/or fix the secondary seal device 42 to the ring structure 44.
