A two-piece seal assembly includes first and second seal subassemblies, each shaped as a semicircular ring. The first seal subassembly has a first stator subassembly and a first rotor subassembly that cooperate to form a first semicircular segment of a labyrinth. The second seal subassembly has a second stator subassembly and a second rotor subassembly that cooperate to form a second semicircular segment of the labyrinth. The first and second stator subassemblies, when affixed to each other, form a ring-shaped stator that encircles a rotation axis. The first and second rotor subassemblies, when affixed to each other, form a ring-shaped rotor that encircles the rotation axis and can rotate about the rotation axis relative to the stator. When the first and second seal subassemblies are affixed to each other, the first and second semicircular segments meet such that the labyrinth encircles the rotation axis.
