Product details

The Hayward SPX3000BN is the genuine replacement diffuser for the Super II pump, covering models rated .5 HP to 1.5 HP full rate and .75 HP to 2 HP up rated. It is molded in plastic, the same as the original.

Why the diffuser matters

The diffuser wraps the impeller and turns the speed of the water leaving the vanes into usable pressure. A cracked or distorted diffuser lets water recirculate instead of moving forward, so the pump sounds normal but the filter gauge and the return flow both drop.

What to look for

Check the face where the impeller runs for cracks, look at the mounting bosses for chips, and see whether the part still seats tightly. Any of those means the diffuser is done.

If you are already replacing the impeller or the shaft seal, do the diffuser at the same time. The pump is apart, the parts wear together, and a new impeller in a worn diffuser will not give you the flow you paid for.

Questions and answers

What people ask about this product, answered by our pool techs.

Which Super II pumps does this fit?
Super II pumps rated .5 HP to 1.5 HP full rate, and .75 HP to 2 HP up rated.
What does the diffuser do?
It surrounds the impeller and converts the water speed leaving the impeller into pressure. Without it, the pump moves water but loses much of its head.
How do I know mine is bad?
Look for cracks at the impeller opening, chips around the mounting bosses, or a loose fit against the impeller. Any of those show up as reduced flow and pressure.
Is this a genuine Hayward part?
Yes. It is the Hayward OEM diffuser, part number SPX3000BN.
