Just put in a new well pump (Goulds 10GS10). I know it is slightly oversized (220 foot well, ~100+ ft static head) and I am already planning on adding CSV, etc. to modulate flow. But in the meanwhile, I noted that the brand new pump is drawing ~9.1-9.2 amps. This is right at its SFA rating, and two amps above the full load rating. The amperage does not vary much over the time its running, so it is not just start-up draw. While testing, I measured AT LEAST 13GPM into 50PSI tank pressure, which on the Goulds charts is consistent with a 120 foot static head estimate. (That measurement was very sloppy and it could be as high as 16 GPM.)
Question: Am I just seeing the high amperage because the pump is operating at the far right of its curve? Or should I worry there is something wrong with the new pump and take other test steps before installing more components?
If I am just under-loading the pump then I assume throttling it down will make everything happy. But I'd appreciate comments from someone smarter and more experienced than me.
Thanks!
