Spa Pump Match Help

Frame + Voltage  + Amperage + Water Connection = Match

Frames" refers to the size of your Motor. All main spa motors have either 48 or 56 frames. 48 frame motors are 5.5" in diameter. 56 frame pump motors are typically 6.5" in diameter. You can also determine the frame size from the bolt spacing- the 48 frame is 3-5/8" and the 56 frame is 4-1/4."

To determine the size of the water connections, measure from outside thread to the outside thread of the pumps wetend.
 If it measures 2 3/8 it is 1 1/2 inch.
 If it measures approx 3 inches, it is 2 inch.
 If it Measures approx 3.5 inches, it is a 2.5 inch.



When matching pumps always use AMPERAGE rather than Horsepower. 
Many times the marketing labeled Horsepower does not accurately represent actual horsepower.
