Product details

The Waterway 805-0238 is the genuine diffuser o-ring for the Champion 56 frame pump and the related Waterway wet ends: SVL56, Power Defender, Econo-Flo and SMF.

What it seals

The diffuser caps the impeller and directs water into the volute. The o-ring between the diffuser and the housing is what stops water taking the short way around the impeller instead of through it. When that o-ring flattens or hardens, the pump moves less water than the motor is working for, and priming can take longer than it should.

Fitting

Replace it whenever the wet end is open. A used o-ring has taken a set in the groove it came from and rarely seals as well the second time. A silicone based o-ring lubricant on assembly helps it seat evenly and makes the next service easier.

Questions and answers

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

Which pumps does this o-ring fit?
Waterway lists it for the Champion 56, SVL56, Power Defender, Econo-Flo and SMF pumps.
Where does it sit in the pump?
Between the diffuser and the housing in the wet end, sealing the path so water is drawn through the impeller.
Should I replace it during other repairs?
Yes. Any time the wet end is apart for a shaft seal, impeller or diffuser, fit a fresh o-ring rather than reusing a compressed one.
What happens if it is worn?
Water bypasses the impeller instead of being pushed through it. You lose flow, and a pump with a leaking diffuser seal can be slow to prime.
