Quick overview

  • Factory Hayward part Diffuser SPX1616B for the Super Pump.
  • For the 2 HP to 2.5 HP size The diffuser is matched to the impeller, so horsepower has to line up.
  • Super Pump family Carried under Hayward Super Pump SP1600, SP1600X, SP2600 and SP2600X parts.
  • Restores flow A cracked or worn diffuser lets water slip back past the impeller and the pump loses pressure and prime.
  • Molded plastic The same plastic component fitted at the factory.
  • Inspect the impeller with it The two wear as a pair, so look at both while the pump is open.

Product details

SPX1616B is the Hayward diffuser for Super Pump models in the 2 HP to 2.5 HP size, molded in plastic. It is carried under Hayward Super Pump SP1600, SP1600X, SP2600 and SP2600X parts.

What the diffuser does

The diffuser sits over the impeller and directs the flow leaving it. Its close fit against the impeller is what stops water circulating back inside the volute instead of going out to the filter. When it cracks or the sealing face wears, the pump keeps spinning but delivers less, and it becomes harder to prime.

Fitting

Diffusers are sized to the impeller, so the horsepower has to match. Since the two parts wear together, look at the impeller while the pump is open rather than closing it up and reopening it a month later.
