Hi Mike, the UST1101 is a 1HP uprated motor and the UST1152 is a 1-1/2HP uprated motor.  Unless you also change the impeller and the diffuser, you will only be getting the Gallons Per Minute (GPM) of a 1 HP pump, but you would be paying for the increased operational costs of running a 1.5 HP motor.

properly sized pool pump should be sized to turn your pool over in an eight-hour time period. Here are a few other considerations to take into account when increasing your HP:


  • Can your filter handle the increased output of water?
  • Can your plumbing handle the increased output?
  • Should you change your impeller?
  • How quickly will the new motor turn your pool over? (Quicker than eight hours may be overkill)
