The Hayward SPX3016C is the OEM replacement 1-1/2 HP impeller for Hayward centrifugal pool pumps requiring this horsepower-rated component. What It Does The impeller is the rotating hydraulic component at the heart of the pump volute. It accelerates water through centrifugal force to generate the flow and pressure your filtration and circulation system depends on. Replacing a worn or damaged impeller with the correct HP-rated OEM part restores pump performance to factory specification.

Before ordering, cross-reference SPX3016C against the part number stamped or labelled on your existing impeller or listed in your pump's parts diagram to confirm correct fitment for your specific model.
