Compatibility with Executive Euro pumps

This hot tub pump wet end suits all the 48-Frame motors used in the Waterway Executive Euro range, whether your pump is single-speed or 2-speed.

If your pump is a 56-Frame model, you need the Waterway Executive 56-Frame wet end instead. Not sure which one you have? Read Do I need a 48-Frame or 56-Frame wet end? before ordering.

How to choose the right HP version

The four impeller versions are named 2 HP, 3 HP, 4 HP and 5 HP. Be careful: these names follow the American versions of the pumps, so the correct wet end will show a higher power rating than your motor.

To pick the right one, look for a reference on your old wet end or impeller, not on the motor. If in doubt, the following guide applies:

• 3 CV pour un moteur de moins de 1500 W
• 4 CV pour un moteur entre 1500 et 1800 W
• 5 CV pour un moteur de plus de 1800 W
