Corrosion In Pumps And Other Damage Mechanisms

Abstract

The successful application of pumps in handling a variety of fluids depends upon knowledgeable design considerations, and the selection of the correct materials for the liquid environment. A previous tutorial “Corrosion in Pumps” addressed many of the considerations that must be taken into account to prevent accelerated degradation resulting from corrosion. Other mechanisms of damage that can limit the useful life of these machines are examined. Mechanical damage mechanism can render a pump useless if proper design and material selections are not done upfront. As is the case with most pumps, a corrosive environment will influence the useful life of the material in the pump. The engineering challenge is to design and build a reliable pump where both corrosion and mechanical damage mechanisms are attempting to render the pump useless.
