PUMP CONSTRUCTION MATERIALS.

The ability of a pump to perform a given function satisfactorily may depend on whether the unit is constructed of materials having specific strength and resistance properties. A material's performance in a pumping application provides a good indication of whether it is suitable for pipe, valves, fittings, and other fluid-handling equipment. Pumps handle a variety of materials at varying velocities and temperatures and are thus subject to corrosion, erosion, wear, and thermal deformation. The article discusses materials commonly used for centrifugal, sump and rotary pumps.
