ABSTRACT:
A centrifugal pump for pumping fiber suspensions includes a centrifugal pumping housing (50) having an inlet (52) and an outlet for the suspension and a centrifugal impeller within the centrifugal pump housing. A vacuum pump (70) is placed adjacent the centrifugal pump housing (50) and includes a vacuum pump chamber defined by first and second opposed side walls (110, 112) and a vacuum pump rotor which is eccentrically mounted within the vacuum pump chamber. The rotor has radially extending opposed side edges facing the vacuum pump side walls (110, 112) forming a clearance therebetween. The pump includes a conduit within at least one of the vacuum pump side walls (110, 112) for supplying a sealing liquid to the clearance (122) between the rotor and at least one of the side walls of the vacuum pump chamber (76). Flushing liquid may be supplied through the same sealing liquid conduits or separately therefrom. The centrifugal pump may include a fluidizing impeller.
