Simply they show you a 1 HP up rated motor which in reality is a 3/4 HP full rated motor. The 3/4 HP full rated pump comes off of the exact same assembly line as the 1 HP up rated pump. All the parts are the same. The only difference is the label.
Pictures display the replacement motor and the pump that the motor will fit. These motors are all Full Rated motors. Up rated motors carry the "U" in front of the code IE USN1102, USN1202 etc. Don't forget to change the mechanical seal when replacing your motor. US Seal for the Northstar pumps is the PS3890 in our store.
