Pentair / Sta-Rite C105-137PDBA Impeller (1.5 HP Full-Rated / 2.0 HP Up-Rated) for Max-E-Glas & Dura-Glas Pumps
The Pentair / Sta-Rite C105-137PDBA is an OEM closed-face impeller designed for select Sta-Rite Max-E-Glas and Dura-Glas in-ground pool pump wet ends. This impeller is commonly specified for 1.5 HP full-rated or 2.0 HP up-rated pump configurations (application-dependent) and threads onto the pump motor shaft to generate water flow and pressure.
Key Details
- Manufacturer: Pentair / Sta-Rite
- Part Number: C105-137PDBA
- Impeller Style: Closed-face
- Rating: 1.5 HP full-rated / 2.0 HP up-rated (match to your exact pump/motor configuration)
- Common Pump Families: Sta-Rite Max-E-Glas and Dura-Glas (in-ground)
- Fastening: Uses an impeller screw (commonly specified as C3012, sold separately)
What This Impeller Does
- Transfers motor power to moving water to produce pump flow and pressure.
- Works with the diffuser to direct water efficiently through the volute and out to your plumbing.
- Restores performance when the original impeller is worn, cracked, debris-damaged, or stripped at the hub.
Common Compatibility Notes
- Used on select Sta-Rite Max-E-Glas and Dura-Glas full-rate pump models that specify C105-137PDBA in the parts breakdown.
- Best practice: match the impeller part number from your pump model’s parts diagram, or compare the old impeller to confirm correct HP rating and screw-style design.
When to Replace
- Reduced flow/pressure after the basket and suction path are confirmed clear
- Cracked hub, broken vanes, or visible wear at the impeller eye
- Impeller stripped on the shaft or seized from debris
- Persistent rattling/grinding traced to wet-end damage
Installation Notes
- Disconnect power at the breaker and relieve system pressure before opening the pump.
- Replace the mechanical shaft seal whenever the impeller is removed to help prevent leaks into the motor.
- Inspect the diffuser and volute for cracks, scoring, or debris damage that can reduce performance or cause repeat failures.
- Use the correct impeller screw if your pump configuration requires it (sold separately); do not reuse a corroded or stripped screw.
- Tighten components evenly during reassembly to avoid pinched O-rings and air leaks.

Maintenance Tip
Most impeller problems start with restricted suction or debris bypassing the basket. Keep the pump basket clean, maintain proper pool water level, and address suction-side air leaks early to reduce cavitation and protect the impeller, diffuser, and shaft seal.
