Abstract
Composite suction liners and associated centrifugal pump architectures are described herein which, in some embodiments, provide enhanced operating lifetimes under abrasive slurry conditions. For example, a composite suction liner includes a suction liner substrate and a monolithic cladding metallurgically bonded to a face of the suction liner substrate, the monolithic cladding comprising metal matrix composite including a hard particle phase dispersed in matrix metal or alloy.
