Summary:This chapter introduces the mechanisms of erosive wear, the various materials used in high wear applications, and some of the more useful methods for erosive wear testing. This leads to an overview of wear modeling techniques and a discussion of the operational and design considerations that affect wear performance in slurry pumps and pipelines. A particular focus is given to the centrifugal slurry pump. Since the pump’s primary function is to add energy to the slurry, the fluid velocities and accelerations within its wetted passages are high. This results in high wear rates, making the slurry pump one of the most maintenance-intensive pieces of equipment in the slurry processing operation. To this end, a detailed overview is provided of the insight that experience and numerical modeling have provided into the wear performance of slurry pump wet-end components.
