Pentair Dyna-Glas Impeller 2HP Full Rate | C105-236PDA

Pentair / Sta-Rite 2 HP Full-Rated Impeller for Dyna-Glas, Dyna-Max, Dyna-Pro, and Dyna-Wave Pumps | C105-236PDA

The Pentair / Sta-Rite C105-236PDA is a genuine replacement closed-face impeller designed for select Sta-Rite pump wet ends that use a 2.0 HP full-rated impeller. Replacing a worn, cracked, or damaged impeller can restore proper flow and pressure when your pump has reduced performance (after confirming baskets, filter, and plumbing are clear).

Common Signs You Need a New Impeller

• Noticeably reduced flow or pressure even with a clean filter and baskets
• Grinding/rattling from the wet end (debris damage or broken vanes)
• Visible cracks, chips, or worn vanes on the impeller
• Poor priming or performance that returns briefly after cleaning, then drops again

Installation Notes

• Turn off power at the breaker and relieve system pressure before opening the pump.
• Inspect the diffuser and seal plate for cracks/warping while the pump is apart.
• When replacing an impeller, it’s smart to replace the shaft seal at the same time to prevent leaks.
• Clean debris from the volute and diffuser passages before reassembly.
• After reassembly, confirm the motor spins freely by hand and check for leaks on startup.

Maintenance Tips

• Keep skimmer and pump baskets clean—debris that reaches the wet end is a common cause of impeller damage.
• If flow drops suddenly, check for blockages before assuming the impeller has failed (baskets, filter, suction line, and return restrictions).
• Fix suction-side air leaks early; running with air can reduce performance and increase seal wear.
• Winterize properly in freeze-prone areas—ice expansion can crack housings and damage internal wet-end parts.
