    High Amps, high temperature on 2hp pump system

    Hey everybody
    I'm new to this site/community. I am an instrument tech at a power plant and a little embarrassed as to why I can't figure out why my pool pump draws so many amps. Let me start by saying this is a brand new motor/pump assy. I just purchased Hayward Super II HP Pool Pump because I was on my 3rd or 4th motor on my other 2 hp Jandy pump. I got tired of replacing motors on the other pump and just bought the Hayward. I have a 30 amp service to my pool control box fed with #6. It's about 75 ft run. My pool control box has a mechanical timer that allows the pump to run about 6 hrs a day. There is a 20 amp GFCI breaker in the control box that supplies the mechanical timer and motor. all wires are #10 to the timer and to the motor. The motor is six ft away from the box. The DE filter is clean with a 12 psi (new Gauge) reading. With skimmer and bottom drain vales fully open the the suction of the pump, and waterfall and wall return jets valves fully open my amps run 12.5. The FLA of the motor is only 10.8. And with my IR gun the surface temp of the motor displays 160 f. I played around with the valves by closing it off restricting flow, and my amps do go down, but I know I shouldn't have to do that. I may be leaving something out, so any ideas please..

    Welcome to TFP!

    That is a big pump and it is going to use a lot of power. That temp does seem a little higher than it should be.

    Yeah I agree it's going to pull some power, and I'm ok with that. I just don't like that it seems to be working really hard for no reason.

    Have you verified the input voltage at the pump while running? Which exact pump do you have?

    Am I able to put a 1 1/5 hp motor on this pump?

    You can put a 1.5 on that pump but would need to change the impeller at the same time.
