How do I know if my hot tub pump has a 48 Frame or 56 Frame motor?

Firstly dismantle your old hot tub pump by removing the four bolts that attach the wet end to the motor. At the rear of the motor, you will have the rear end of the motor shaft that runs all the way through the motor and threads onto the impeller inside the wet end. This shaft end will have a large flat slot for a screwdriver to go onto, simply get another screwdriver and trap the impeller inside the wet end and then unthread the motor shaft from the impeller. You will now have the wet end removed from the motor and you can work out if you have a 48 frame or 56 frame EMG motor.

48 Frame EMG Motors

There is only one type of 48 frame sized motor and will fit all modern day 48 frame pump wet ends. Measure diagonally the centres of two of the four bolt holes that attached the motor to the wet end, this measurement will be 130mm.

56 Frame EMG Motors - 6.3"

The modern 6.3" 56 frame motors will fit all modern day 56 frame pump wet ends. Measure diagonally the centres of two of the four bolt holes that attached the motor to the wet end, this measurement will be 147mm.

56 Frame EMG Motors - 6.1"

These 56 frame 6.1" motors are an old size and now no longer manufactured and you will need to replace your complete hot tub pump. These are NOT measured diagonally, they are measured side to side and the centres of two bolt holes that attached the motor to the wet end are 102mm. These are generally found on old Aqua-flo XP2 pumps.

Top Tips

We recommend replacing the mechanical shaft seal in your wet end as if this is leaking will cause your new motor to fail prematurely. See related products.
