ABSTRACT:
A centrifugal pump adapted for use in a fermentor is provided. The fermentor includes an outer vessel which has mounted therein a generally centrally located draft tube. A centrifugal pump is mounted adjacent to one end of the draft tube and is operably connected to a motor for rotation thereby. The centrifugal pump includes a plurality of vanes radiating outwardly from a region adjacent the center of rotation and cover members positioned on opposite sides of the vanes. The vanes and the cover members cooperate and define flow paths through which medium can be induced to flow due to the centrifugal forces created during rotation of the vanes. The vanes have a distance between respective side boundaries thereof which is less at a position inwardly of the outer disposed end of the vanes than at the outer disposed ends of the vanes.
