A self-priming pump comprises a casing enclosing first and second impellers rotating on a common shaft. The first impeller in an associated impeller cavity pumps a liquid from an inlet to a first output port. The second impeller in an associated impeller cavity pumps the liquid from the inlet via an intake port to a second output port, the second impeller having a positive displacement for evacuating gas from the first impeller cavity. The first and second output ports are connected to an outlet with means provided for preventing reverse fluid flow into the first output port.
