The Hydraulic Institute (HI) and its Members have worked closely with the Department of Energy (DOE) throughout the rule-making process for the Energy Conservation Standard on Commercials Industrial Pumps. As part of that process, HI’s Pump System Performance Metric (PSPM) committee supported the industry by working with the DOE to develop a tool to evaluate the PEI of pumps. This tool will help pump manufacturers evaluate how their pump efficiencies stack up to the proposed minimum efficiency levels which will be set in the Energy Conservation Standard. The effort of the committee and HI members at large was rewarded today, June 12, 2015, when the DOE released the Pump Energy Index (PEI) calculation tool to the public.
