I just installed a new (Century A.O. Smith B975) 2 speed motor on my 1hp Hayward Super pump (SP2607X10).
Here are some readings I have taken to date.
High speed- filter pressure- 8.5psi. Seems to run the same as the older single speed motor did.
amps- 5.75 Didn't check older single speed motor amps but seems low for high speed.
Low speed- filter pressure- 1psi Barely moves the gauge
1-1/2" piping both inlet and outlet of pump.
27000 gallon pool
It seems to me that I'm not saving that much on low speed by having to run twice as long. I know the amp readings aren't true power indicators in wattage, but should still give me some indication of power usage. Do these amp readings seem normal?
I'm not sure what the flow is from the pump, I'm guessing around 55 GPM using the pump curve and total head (45ft)estimates. I need to get a gauge for the suction side to figure out actual head loss. The flow on low speed seems to be a bit lower than half of the high speed if that's possible. The strainer basket is pretty full when on low speed and even primes the pump from being off all night.
Without a power meter and flow gauge I'm not sure the system is working properly or as efficient as I expected.
So should I be concerned?
