ABSTRACT:
A centrifugal pump of the type adapted to pump high consistency fiber suspensions includes impeller vanes having portions which are immediately adjacent the fiber suspension in the interior of a vessel from which the suspension is to be pumped. The pump additionally includes a sideplate which is mounted directly to the vessel containing the fiber suspension so as to permit the impeller of the pump-to be brought in close proximity to the fiber suspension in the vessel. The sideplate additionally includes elongated portions that extend along the outer contour of the vanes of the impeller to determine the directions from which fiber suspension enters the impeller of the pump.
