Hey, Guys. I recently replaced my 1.5 HP motor on the Hayward SP3010X15AZ unit. All plumbing is 2" serving a normal 15,000 gallon pool with spa water feature. I opted for a single speed

High Amps
Hey, Guys. I just replaced the 1.5 hp motor, seals, and impeller on my Hayward pump. I noticed that when I open all three suction valves the motor draws high amps. Only when I close off any combination of the three and see some turbulence in the suction filter/screen will the amps drop to...

I would drop the impeller down to a SPX3007C or even a SPX3005C.
The SPX3010C should not be drawing that many amps.
Can you show a picture of the impeller and the part number stamped on it?
Does the impeller spin freely or is it binding?
Did you verify that the voltage is good under load?

I'll check the exact voltage in a little while, but the motor is tripping with amps under nameplate rating.
That's leftover mold. When I put this motor in all leaks went away.
That is about 2126 watts.
I would expect closer to about 1,500 Watts.
Since the amperage is within the label, I would file a warranty claim for a replacement motor.
I would drop the impeller to a SPX3005C unless you need a lot of flow.

I did get a refund on the motor. Per the hayward chart I've got the right impeller. If this motor's tripping at or below flc then the problem is the motor, right?
The pump is drawing more amps than it should be and this happened before in your other thread from
The total power draw should be a maximum of about 1,650 to maybe 1,850 at the highest.
2126/1,650 = 1.3 time too much power draw.
So, something is off.
Check the frequency and power factor.
Maybe the start capacitor is not being removed from the circuit due to a defective centrifugal switch?

James, that's why I replaced that motor with this one I'm writing about. Everything else electrical in the house works fine. I agree something is off.
This shows that there was some interference between the impeller and the diffuser.
Maybe you are getting some interference or maybe the seal is in backwards or something.
Do you have this impeller ring? SPX3005R.
Maybe see how the motor runs without being in the housing.

I'm certain everything is in correctly. The bottom line is that this motor is tripping at 9 amps, and flc is 9.3.
