low-pressure oxidizer turbopump это первый слабенький бустерный насосик кислорода. основной там немного серьезнее
The main pump boosts the liquid oxygen's pressure from 2.9 to 30 MPa (420 to 4,350 psi) while operating at approximately
28,120 rpm, giving a power output of 23,260
hp
при том что лимитирует все явно водородник: бустерный
he LPFTP operates at around 16,185
rpm, and is approximately 450 by 600 mm (18 by 24 in) in size. It is connected to the vehicle propellant ducting and is supported in a fixed position by being mounted to the launch vehicle's structure.

и основной
The HPFTP is a three-stage centrifugal pump driven by a two-stage hot-gas turbine. It boosts the pressure of the liquid hydrogen from 1.9 to 45 MPa (276 to 6,515 psia), and operates at approximately
35,360 rpm with a power of 71,140 hp.

175 600 лс на кислороде(600 атмосфер) и 77 760 (500 атмосфер) для керосина, но вроде только 13850 оборотов в минуту. но турбины разные, насосы кислорода тоже. в общем не ясно, что сравнивать
