ABSTRACT:
A fluid pump having an outer cylindrical housing (10) rotating relative to an inner hub (44) from which radially projects a probe (52) apertured in its external surface to be exposed to the flow therepast of an annulus of operational liquid (14) constrained in a circular path of motion by the rotating housing, the probe having an internal passage for communicating the aperture with a first external space and the inner liquid-free space in the housing having an outlet for communicating with a second external space. In use, fluid to be pumped is sucked out of the apertured probe to emerge as fluid bubbles which migrate through the rotating liquid annulus to the liquid-free center, then to pass to the outlet.
