Abstract
A pitot pump assembly including a rotating drum 12 having a central bore 14 and a cavity 20 between its two axial ends and at least one radially extending opening 22. A stationary shaft 24 is inserted within the bore 14 and includes a plurality of fluid passages 26. The shaft 24 has one or more bearing surfaces 28 and sealing surfaces 30 between the shaft 24 and the rotating drum 12. A unitary pitot sub-assembly 32 is inserted through the radial opening 22 of the rotating drum 12 and has one or more radially extending pitot tubes 36 in which to receive fluid from within the cavity 20 of the rotating drum 12. A sleeve 48 is disposed on the rotating drum 12 for sealing the opening(s) 22 and an outer housing 52 is secured to the stationary shaft 24 and encases the rotating drum 12.
