According to the U.S. Department of Energy (DOE), pumping systems use a significant amount of energy in process plants (http://goo.gl/TiBA72). To be more specific, let’s look at petroleum refining — pumping systems consume almost 60% of the total energy used by machine drives (mechanical rotating equipment). In the chemicals sector, this number is still a respectable 28–30%. So, shouldn’t we take an energy efficiency “magnifying glass” to our pumping systems and reap some benefits from possible low- or no-cost measures?
