  • Commercial pump duty CSPH and CCSPH are Sta-Rite commercial pumps, not residential units.
  • Listed as 7.5/20HP Our source gives the horsepower reference as 7.5/20HP without stating whether that is a range or two ratings, so it is carried verbatim.

Product details

Sta-Rite 16830-0120 is the wear ring listed under Sta-Rite CSPH and CCSPH commercial pump parts, with the reference 7.5/20HP CSPH/CCSPH.

What a wear ring does

A wear ring sets the running clearance between the impeller and the pump casing. That clearance is the only thing stopping discharge pressure from bleeding back into the suction side inside the pump. As the ring wears the gap opens, recirculation increases, and the pump moves less water for the same power. On a commercial installation that shows up as reduced turnover and a higher electricity bill long before anything makes a noise.

The horsepower reference

Our source lists the application as 7.5/20HP CSPH/CCSPH and does not say whether that describes a range or two ratings. We have carried it exactly as written rather than interpret it. Match part number 16830-0120 against your own pump before ordering, since our facts do not carry ring dimensions to check against.

Questions and answers

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

Which pumps does this fit?
It is listed under Sta-Rite CSPH and CCSPH commercial pump parts, with the reference 7.5/20HP.
Does 7.5/20HP mean 7.5 through 20 horsepower?
Our source writes it as 7.5/20HP and does not say whether that is a range or two separate ratings. We have carried it exactly as listed rather than interpret it, so confirm against your pump before ordering.
What does a wear ring do?
It sets the running clearance between the impeller and the casing. As the ring wears, more water recirculates inside the pump instead of going out the discharge, so flow drops and the motor works harder for the same result.
How do I know mine needs replacing?
A pump that has lost flow with a clean strainer, a clean filter and no air leak, and that draws more current than it used to, is a candidate. Confirm by measuring the clearance when the volute is open.
