Product Details
Waterway Executive Impeller - 4HP (New Style)
Genuine replacement Waterway impeller for the executive range of wet ends.
The new style impeller may look slightly different, but they are retroactive with the old impellers and will fit any executive volute housing.
Older Impellers are GREY, new version is BLACK.
The change improves the impeller's concentricity, reduces vibration which in turn reduces wear on the pump and more importantly improves performance.
Top Tip:
When replacing an impeller we recommend to replace the shaft seal as well.
