An impeller is rotatable in the pumping chamber and includes a plurality of impeller blades designed for forming trailing vapor cavities within a liquid in the chamber to generate low pressure regions behind the blades upon rotation of the impeller. A fluid inlet is provided to the chamber radially inwardly of the low pressure regions and in communication therewith. A fluid outlet is provided from the chamber radially outwardly of the fluid inlet and in an area of the chamber whereby the fluid can be pumped from the chamber. Liquid inlets are provided to the chamber in the area of the impeller blades for flushing the low pressure regions behind the blades.
