Abstract (en)
[origin: GB2581382A] Disclosed is a pump comprising a housing element 20 and a further element 10, where one of the elements has a helix extending towards the other of the elements which has at least one liquid opening, the two elements and the helix form a path from a gas inlet to a gas outlet, with the further element mounted concentrically within the housing element such that the two can rotate relatively to each other, the helix narrowing as it extends from the element it is associated with and the at least one liquid opening configured to create a liquid blade when liquid is expelled such that it drives gas from the inlet to the outlet when the elements rotate. The pump may be a vacuum pump or a wet scrubber for an abatement system. Also included is a method of pumping a gas utilising a liquid blade and a helical element.
