New development! It appears that the pump is actually a Northstar. The motor must have been replaced by the previous owner, and I got Super Pump from the motor label. So the pump model is sp4020ns. It appears that this requires a 2hp pump... Can anyone confirm that for me?
The pump model doesn't match with the impeller number. If the impeller is a sp4007, you would need a 3/4 HP full rated motor in a 56j frame. Where did you get the pump model#?
