Determining Pump Power Usage

[HeyEng]

Perhaps someone can help be decipher how much energy a pump might use. I understand the basic concept of determining wattage and the conversions, but it seems like pool pump motors are marked in their "own special way". In my case, I have a full rate 1 HP two speed with a service factor of 1.85 The identiplate shows AMPS as "SF 8.5 / 1.5" Would this indicate that the maximum amperage (for given service factor) would be 8.5 on high speed and 1.5 on low? I attached the identiplate for clarification. Thanks in advance!

Correct, the full load amps are 8.5 with the low speed being 1.5 amps.

That makes the full load at about 1,955 watts with the half speed at about 345 watts.

Most pumps are about 1,000 watts per total hp.

Fantastic...thanks!
