FAQ

Energy-Efficient Pumps — frequently asked

How much does an IE5 motor save vs. IE3?

IE5 motors are typically 3–5 percentage points more efficient than IE3 at rated load, and up to 10 points more efficient at part load. Combined with VFD control this delivers 15–30% total annual pumping-energy reduction; payback is usually 1–3 years.

Is IE5 available for large industrial pumps?

Yes — IE5 permanent-magnet and synchronous-reluctance motors are now available up to 375 kW from major manufacturers, covering essentially all chilled-water, condenser-water and process pumping duties.
