Abstract
The weight and volume of a centrifugal fuel pump ideally suited for use in a fuel system for a turbine engine (12) may be reduced in a construction including a single shaft (10) mounting an inducing impeller (18), an impeller (22) for a regenerative pump, and an impeller (24) for a centrifugal volute pump. Hydrostatic bearings (26), (28) journal the shaft (10) within a pump housing (14) and are provided with fuel under pressure via a conduit (30) connected to the outlets of the regenerative pump and the centrifugal volute pump defined by the impellers (22) and (24), respectively.
