    $\begingroup$ It is not possible to use the same turbopump for fuel and oxidizer for all propellants that could be mixed only in the combustion chamber. $\endgroup$

    $\begingroup$ Do you perhaps mean having fuel and oxidizer turbopumps on the same shaft, powered by a single turbine, as opposed to two shafts, each with its own turbine? $\endgroup$ Nov 10 at 10:46
