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).

Compatibility

  • Sta-Rite Dyna-Glas / Dyna-Max (2 HP): commonly used on models including MPEA6G-155L, MPRA6G-155L, MPR6AG-155LC, MPEA6YG-175L, MPEA6YG-175LS
  • Sta-Rite Dyna-Pro / Dyna-Pro E (2 HP): commonly used on models including MPEA6G-207L, MPE6F-207L, MPEA6YG-207L, MPE6YF-207L, MPRA6G-207
  • Sta-Rite Dyna-Wave series: where C105-236PDA is specified on the parts list
  • Sta-Rite Dyna-Jet TPE series (2 HP): commonly used on models including TPEAG-167LS and TPEAYG-167LS
  • Tip: Always confirm by your pump model and exploded parts diagram. Sta-Rite wet ends can vary by revision.

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.
