Before you compare two motors or pumps, make sure the ratings are being interpreted the same way.

  1. Confirm the horsepower standard.
  2. Check whether the rating is continuous or peak.
  3. Compare voltage, phase, and efficiency where relevant.
  4. Round only after the main calculation is complete.

Small differences in standard or rounding can make two similar values look inconsistent when they are not.
