Full Description

Many facilities consider only the initial purchase and installation cost of a pumping systemdespite the fact that life-time operating costs, especially energy and maintenance costs, can amount tomany times the purchase cost. It is in the best interest of the facility's profitability to evaluate thelife cycle cost of alternative solutions before purchasing and installing major new equipment orcarrying out a major overhaul. Important new methodologies and tools have been developedspecifically for pumping systems and aimed at improving system efficiency and facilityprofitability.This paper discusses the use of a "systems approach" to evaluating pumping systems.Examples from the authors' own experiences and the US Department of Energy's (DOE)Best Practices activities within the DOE Industrial Technologies Program are provided toillustrate this systems approach, which leads to a system optimized for energy efficiency,maintainability, reliability, and performance. This paper includes an overview of thePumping System Assessment Tool, an easy to use software program developed by DOE toidentify energy savings opportunities in existing pumping systems. The paper concludeswith a discussion of Life Cycle Cost (LCC) analysis as a management tool to help facilitiesminimize waste and maximize energy efficiency for new and existing pumping systems. Includes 11 references, table, figures.
