Pentair / Sta-Rite C105-138PEBA Closed-Face Impeller (3/4 HP Full-Rated / 1 HP Up-Rated, 2-Speed)
The Pentair / Sta-Rite C105-138PEBA is an OEM closed-face impeller designed for select Sta-Rite Dura-Glas and Max-E-Glas in-ground pool/spa pumps in 2-speed applications. This impeller is commonly identified as a 3/4 HP full-rated or 1 HP up-rated impeller, and it features a hole for an impeller screw (a key distinction from similar impellers that do not use an impeller screw).

What This Part Does
- Transfers motor power to moving water through the pump volute to produce flow and pressure.
- Works with the diffuser to shape water movement for efficient circulation.
- Restores performance when the original impeller is cracked, worn, or debris-damaged.
When to Replace the Impeller
- Reduced flow/pressure after the basket and plumbing are confirmed clear
- Cracked hub, damaged vanes, or worn impeller eye
- Impeller stripped on the shaft or seized from debris
- Repeated loss of prime or unusual noise traced to wet-end damage
Installation Notes
- Disconnect power at the breaker and relieve system pressure before opening the pump.
- Match the impeller to your pump’s exact model and motor/HP configuration to ensure proper performance.
- If your setup uses an impeller screw, confirm the screw is present and in good condition during reassembly.
- Replace the mechanical shaft seal whenever the impeller is removed to help prevent leaks into the motor.
- Inspect the diffuser and volute for scoring or cracks that can reduce performance or cause repeat issues.

Maintenance Tip
Most impeller damage starts with debris bypassing the basket or from running the pump with restricted suction. Keep the pump basket clean, maintain proper water level, and address suction leaks early to help protect the impeller, diffuser, and shaft seal.
