Abstract

This invention is concerned with a centrifugal pump, particularly adapted for pumping liquids with a heavy gas content. To separate the gases from the liquids the impeller is provided with ducts leading from the central inlet to the peripheral outlet of the pump, the ducts being of progressively smaller cross section from the inlet to the outlet and openings are provided through the impeller disc for the escape of gases. There are a plurality of openings and the cross sectional area presented by the openings for the escape of gas is progressively lesser from the inlet region to the outlet region.
