There are some controls that maintain constant flow that will increase current/power but those are rare for these types of pumps.
This is what I am talking about. I don't argue with you on the pump that gets to run wild when resistance drops. This isn't how my well pump works so it wasn't foremost on my mind.
But you wanted my data. I have a variable speed well pump. If you pump 10gpm/50 psi, it draws less current than it does at 10gpm/90 psi. The reason is that it has a $1500 controller which, no doubt, will not be found on most pumps.
