ABSTRACT:
An inducer for a high speed centrifugal pump includes a shaft located upstream of the inlet eye of the centrifugal pump concentrically within an inlet bore; and further includes a plurality of axial blades on an inducer shaft for producing a boost pressure to the inlet of the centrifugal pump and wherein means are included to direct a spray of fuel in a direction radially of the longitudinal axis of the shaft immediately upstream of the blades to reduce the amount of fuel flow across the inducer with a resultant lowered pressure rise than would otherwise occur.
