Abstract
A centrifugal pump for moving gaseous liquids comprises a gas separator situated in the suction chamber of the pump. The outlet of the gas separator is aligned with the inlet of the impeller, the degased liquid passing through said outlet. The separated gas is drained off to the ambiency through a tapped hole in the pump casing, to which a ventilator is connected. The gas separator is mounted in its fitting position after it has been carried from the pressure chamber of the pump and through an opening in a partition between the suction chamber and the pressure chamber and further on into the suction chamber. The gas separator is retained in its fitting position by means of securing means in the positions in which the water and gas outlets of the gas separator are situated. As a result, the pump casing may be manufactured from a simple and relatively small moulding piece. The pump casing need not comprise several parts.
