<p>A fluid pump has an outer cylindrical housing (40) rotating relative to a central hub (44) from which projects a radial probe (52) apertured in its external surface to be exposed to the flow therepast of a rotating annulus of operational fluid (14). The probe has an internal passage (54) for communicating the aperture (56) with the exterior, so that fluid is drawn into the pump due to suction created at the probe. A Pitot tube (26) is also exposed to the rotating fluid, and from an aperture thereof fluid is expelled from the pump. The fluid drawn into the probe (52) may be a gas to be scrubbed, and the rotating operational fluid may be an active liquid to dissolve impurities from the gas.</p> |
