A method of and apparatus for pumping fluids wherein a rotating ring of liquid traverses a hollow probe which has a surface aperture out of which the fluid to be pumped is sucked into the rotating liquid ring, wherein the fluid migrates to a collection region inside the rotating liquid ring, from where the fluid can pass to a fluid outlet, and wherein a gas which does not condense under the prevailing operating conditions is also fed to the collection region in order to assist throughput of the fluid being pumped.
