AWWA JAW3833

With the energy crunch upon utilities, it is more important than ever to have the most efficient pump system possible. One energy-saving approach is to base pump system design on "total system analysis," from the selection of the proper pumps (based on system head curves) to the selection of the proper drivers. In addition to saving energy, sound designs also help conserve budgetary resources in inflationary times. Also covered are variable-speed drives, adjustable-speed drives, efficiency of electric motors, efficiency versus power factor, system efficiency, single-pump systems, multiple-pump system:constant speed, multi-pump system:variable speed, and multi-speed system:base-flow pumps. Includes 5 references, tables, figures.
