Abstract: A liquid with entrained gas is fed through a supply pipeline connected coaxially to the suction side of a centrifugal pump, and a gas-discharge pipe has one end portion extending coaxially into the supply pipeline, there being wings arranged to be driven so as to rotate in a path extending around the axis of the gasdischarge pipe and concentric to the pump shaft. The other end portion of the gas-discharge pipe is connected to a vacuum source, and the wings have portions extending axially along this discharge pipe in the vicinity of its opening which receives the gas to be discharged.
