At that time, the starting pump (18) is switched off, via a valving means.
The starting pump (18) delivers fuel until the main pump (14) reaches a speed sufficient to provide adequate pressure for fuel delivery.
A regenerative liquid-ring starting pump (18) is located on one side of the rotor (12), and a centrifugal impeller (14) is located on the other.
The start pump may have a pump portion coupled to a motor-driven portion and the turbo pump may have a pump portion coupled to a drive turbine.
In one configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit downstream of and in series with the pump portion of the turbo pump.
In another configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit upstream of and in series with the pump portion of the turbo pump.
