Although the DOE’s new pump efficiency standards raise the bar for manufacturers to build more efficient pumps, its rating system should not be looked at as a shortcut to efficient pump selection. Careful consideration of part load efficiencies applied to realistic load profiles is still the only way ...
Read MoreUnder the DOE’s new efficiency standards for pumps, all Pump Efficiency Rating (PER) values use a full size or maximum impeller for a given pump and start at the pump’s best efficiency point (BEP). As you may recall from our last post, the new efficiency standard includes two versions of.....
Read MoreNow that the U.S. Department of Energy (DOE) has published the first ever Energy Conservation Standards for Pumps, let’s take a look at some of the finer details of that standard, starting with the associated terminology and what it means...
Read MoreHeat pumps have them. Air conditioners have them. Even light bulbs have them. And now, for the first time in history, clean water pumps have them too.
We’re talking about efficiency standards, officially issued for pumps by the Department of Energy (DOE) on January 4, 2016. These new pump efficiency standards, which will take effect ...
