Abstract
Centrifugal pumps for pumping a pulp suspension and conducting gas away from the pulp suspension are disclosed including a pump housing having an inlet and an outlet, a rotary shaft, an impeller mounted on the rotary shaft within the pump housing, the impeller including a hub and pump blades extending outwardly from the hub, a wheel disk adjacent to the impeller so that the pump blades extend outwardly along the wheel disk, a vacuum impeller within the pump housing behind the wheel disk and including a vacuum pump housing, vacuum impeller blades, a seal for sealing the vacuum pump housing to the rotary shaft, the vacuum pump housing including a suction port for drawing gas into the vacuum pump housing and an exhaust port for expelling gas therefrom.
