ABSTRACT:
A pump for pumping an air containing medium includes rear vanes (11) on the propeller back plate of the pump and a back ball arranged so that a radially widening space is created between the impeller back plate and the rear wall for guiding the flow of the medium, generated by the combined effect of forces with different directions and different intensities directed at the medium in the spaces between the rear vanes, past gas discharge opening (12) in the rear wall of the pump or for retarding the flow thereby preventing the flow from entering the gas discharge opening (12).
