Polymer Composite Industrial Chemical Pumps

Abstract

Polymers are important materials in the design and application of pumps and piping in many chemical processing systems today. The ability of polymer composites to resist chemical attack is the primary reason for use in industrial equipment, creating an economical alternative to high alloy metals and other exotic materials. Discussion includes the principles corrosion, construction of polymer composites pumps, and the use of composites in chemical process applications. Discussion on pump construction includes the design and manufacture of thermosets, thermoplastics, and lined pumps. A user perspective includes pump cost comparisons, equipment selection, application guidelines, sealed versus sealless pumps, piping, and examples of field experiences.
