Overall view of the cut-away turbopump.

The turbine housing is at the bottom, with the first- and second-stage turbine wheels. Both turbopumps run off of a common shaft, which is bolted to the first-stage turbine wheel.

Moving up from the turbine are the fuel turbopump inlet, fuel inducer, and fuel impeller.

Moving downward from the top are the LOX inducer and LOX impeller.
