Suction liner and centrifugal pump comprising the same

Abstract

A suction liner for a centrifugal pump for processing slurries. The suction liner includes a cylindrical portion arrangeable in the casing of the centrifugal pump, and a flange portion which protrudes outwards in a radial direction from the cylindrical portion. The flange portion is arrangeable such that, when mounted in a centrifugal pump, at least a portion of a front end surface of the flange portion of the suction liner abuts against at least a portion of a front end of the impeller to seal an axial gap between the suction liner and the impeller, and at least the front end surface of the flange portion is made of a low friction polymer. A centrifugal pump for processing slurries can be used with the suction liner. The suction liner and the centrifugal pump allow preventing recirculation of pumping liquid in a centrifugal pump and, thereby, reducing wear.
