Abstract

A pumping device for multi-phase fluids in which in a disc casing of toroidal peripheral profile provided on its inner surface with a tube of Pitot tube type connected to a delivery pipe there is rotatably mounted a bladed impeller arranged eccentric to the casing axis in a position approximately diametrically opposite said Pitot tube, a second delivery pipe being provided in that casing region opposite the intake pipe about the plane containing both the axis of the casing and the axis of the impeller and in proximity to this latter axis, automatic valves being provided in the pipes. <IMAGE>
