Quick overview

  • Genuine Hayward SPX2300B is the factory diffuser, not an aftermarket copy.
  • Covers MaxFlo VS and MaxFlo XL Listed for SP2300VSP, SP2302VSP and SP2302VSPND variable speed pumps and the SP2300X series.
  • Works with the impeller The diffuser directs flow off the impeller into the volute, so the two only perform as a matched pair.
  • A common wear item Diffusers crack and wear at the impeller face, quietly costing flow long before the pump sounds wrong.
  • Restores rated flow Fitting a new diffuser alongside a good impeller brings the pump back to its designed output.
  • Check the seals while you are in there The pump has to come apart to reach the diffuser, so it is the moment to look at the o-rings.

Product details

The Hayward SPX2300B is the genuine diffuser for the MaxFlo VS and MaxFlo XL pumps. It covers the SP2300VSP, SP2302VSP and SP2302VSPND variable speed models and the SP2300X series.

What the diffuser does

The diffuser sits over the impeller and shapes the water leaving it, turning speed into pressure as the flow moves into the volute. It is a quiet part of the pump in the sense that it has no moving pieces, but a cracked or worn one costs real flow.

How you know it is worn

Diffusers wear at the face that runs closest to the impeller, and they crack around the mounting features. A pump that has lost flow without an obvious blockage, a bad seal or a worn impeller is worth opening to look at the diffuser.

While the pump is apart

Reaching the diffuser means splitting the pump, so it is the natural moment to inspect the o-rings and the impeller. Fitting the diffuser against a worn impeller only recovers part of the lost performance.

Questions and answers

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

Which pumps does this diffuser fit?
The Hayward MaxFlo VS models SP2300VSP, SP2302VSP and SP2302VSPND, and the MaxFlo XL SP2300X series.
Is it a genuine Hayward part?
Yes. It is Hayward OEM part SPX2300B.
What does a diffuser do?
It sits over the impeller and directs the water leaving the impeller into the volute in a controlled way. That conversion of speed into pressure is where a large part of the pump head comes from.
Should I replace the impeller at the same time?
If the impeller is worn or the vanes are damaged, yes. The two work as a pair, and a new diffuser against a worn impeller gives back only some of the lost flow.
