Product details

This is the Sta-Rite C105-137PDA impeller, sized for 2 horsepower full rate and 2-1/2 horsepower up rate pumps. It is listed within the Sta-Rite Max-E-Glas and Dura-Glas pump parts group.

What the impeller does

The impeller is what actually moves water. Its vanes are narrow, so debris that gets past the basket lodges in them, and years of running wears the vanes down. Either way the symptom is the same: weak returns, poor skimming, and a pump that sounds normal while shifting far less water than it should.

Fitting it

Impellers are matched to horsepower and rating, so read the pump label instead of going by the size of the motor. Getting the impeller off means disturbing the shaft seal, so replace that at the same time. Reusing an old seal is the usual reason a freshly rebuilt pump starts weeping between the motor and the wet end.

Questions and answers

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

Which pumps does this impeller suit?
Pumps rated 2 horsepower full rate or 2-1/2 horsepower up rate, within the Sta-Rite Max-E-Glas and Dura-Glas parts group. Confirm the rating on your pump label before ordering.
What is the difference between full rate and up rate?
It is how the motor is rated. The same impeller here serves a 2 HP full rate pump and a 2-1/2 HP up rate pump, because their hydraulic output is comparable.
Can I fit a larger impeller for more flow?
No. The impeller has to match the motor rating and the plumbing it was designed around. Fitting the wrong size overloads the motor or starves the pump.
What should I replace while I am in there?
The shaft seal. It has to be disturbed to get the impeller off, and putting the old one back is the most common reason a rebuilt pump leaks at the motor.
