Pumps and pumping systems account for 25% of the energy consumed by electric motors in the United States. In pumping intensive industries, this number is over 50%. In fact, providing clean drinking water to homes and businesses alone accounts for almost 12.5% of total US pump energy consumption.
To improve the efficiency of pumping systems and reduce their energy consumption, pump users are turning to variable frequency drives (VFDs). Since most pumping systems are designed for maximum service conditions (capacity and differential head), running them at partial load can save considerable energy. So, by precisely matching motor speed to pumping requirements, VFDs can reduce energy costs by as much as 30% or more.
