The first edition of the AIChE(r) manual on evaluating positive displacement pumpsPositive Displacement Pumps: A Guide to Performance Evaluation is the latest text in the AIChE(r) Equipment Testing Procedure series. It provides pump users with concise, easy-to-follow procedures for testing various types of pumps in the field. The manual covers both traditional and state-of-the-art testing methods and takes into account the "imperfect" realities of actual field conditions. User-friendly and complete with numerous helpful illustrations and tables, this reference includes:*Definitions of major terms, with explanations, conversion factors, and nomenclature*Coverage of diverse types of positive displacement pumps: gear; lobe; multiple screw; vane; progressive cavity; diaphragm; and piston/plunger*Descriptions of test preparation logistics, safety precautions, instruments, methods of measurement, standardized tests, and other tests*Coverage of pump-testing for applications handling non-Newtonian fluidsThis is the hands-on reference for chemical engineers, plant managers, and other professionals responsible for evaluating positive displacement pumps. It fills the gap between manufacturers' literature and textbooks and provides practical, effective guidance on troubleshooting and problem-solving in the field.
