Abstract
Disclosed is a slurry conduit for connecting to a centrifugal pump for transporting a slurry mix of solids and liquids. The conduit includes an inclined upstream section having a reduced cross section whereby a concentration gradient formed within the slurry conduit is reduced. The inclined section forces any sliding bed or stratified slurry upwards as it goes towards the apex of the reduced section. The slurry entering the pump has a substantially monolithic or nonstriated composition, which reduces the wear on the pump.
