The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) have implemented several regulations focusing on energy efficiency.

According to the DOE 2014-05 Technical Support Document for Electric Motors (Final Rule), nearly 70 percent of industrial electricity demand is used by industrial motor systems, with a majority of these being rotodynamic pumping systems.

Chances are that the existing pumping systems in your plant are less than optimal. There is a simple process for identifying “bad actors” by following the Hydraulic Institute’s (HI) six-step action plan for evaluating existing pumping systems:

1. Screen and prioritize your pumping systems to identify good performance improvement candidates.
