CASING FOR A CENTRIFUGAL PUMP

摘要

A pump casing for a centrifugal pump of the type that is used to process abrasive slurries is disclosed having at least one side or side liner that has a radially extending portion oriented toward the cutwater of the pump casing to localize the abrasive wear caused by the abrasive slurries to the side of the pump casing. The side liner of the pump is configured with a perimeter edge that is non- circular. The pump casing may preferably be configured with an open cutwater configuration or other suitable configuration for localizing wear to the sides of the casing.
