Description

Positive Displacement Pumps is a current reference guide for positive displacement pumps for both traditional and state-of-the-art testing methods, and serves as a bridge between textbooks and manufacturer's literature by providing equipment testing practices based on technical know-how, practical experience, and academic theory. With its simple, practical focus, this book not only is a resource guide to any engineer's task, but also adds important information to the overall literature of pump fundamentals and operating reliability:
  • Written for field users, and terminology concisely defined.
  • A mentoring guide highlighting areas for troubleshooting problem-solving when performance criteria are not met.
  • Produced with industry consensus and gone through the same rigorous technical review process as other ETPC procedures.
