Turbo Pump

A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use.Turbopumps operate in much the same way as turbocharger units for vehicles: higher fuel pressures allow fuel to be supplied to higher-pressure combustion chambers for higher-performance engines.
