Current Pump Energy Rating (ER)

Find your pump's ER at er.pumps.org

What is ER?

Energy Rating measures pump hydraulic efficiency. Higher = more efficient. Average market pump ≈ ER 6–10. Best available ≈ ER 20–65+.

We'll use the average market ER for your selected pump type and HP from the HI Energy Rating database. This represents a typical pump purchased without efficiency screening — a fair, conservative baseline.

Select pump type and HP above to see the average ER used.
