OK - 800' deep well. Set the pump at 300' due to very high water level about 8 years ago. Added a Franklin pump saver box. Pumping up a hill to a static tank that is about 60 PSI on the gauge when full. Perhaps 140' height. I wrote on the control box, 150PSI test pressure and 9.3 amps draw - 1 HP.
Filled the tank nicely for those ten years. Only pumped it for a few hours a week over those years. Now I still get the 9.3 +/- amp draw, but only 40 PSI dead head pressure. Won't make the tank. Whats the mystery? Clean clear water, no sediment. I must say that I had to set the pump saver or pump tek box at 40% from the get go to get it to run without a trip, so I was outside of range to begin with. Its not tripping at 40, but it will at 45 instantly. Need more stages in the pump head?
Reading the pumptek manual, I will guess now that the pump deadheaded and I have some melted impellers due to a bad match of motor to pump head. Looks like the Pumptek is not dependable on reading a deadhead condition. [?]
