Sta-Rite (BWG)

Sta-Rite (BWG) impellers are replacement rotating water-moving components for Sta-Rite/Balboa Water Group pump wet ends, determining flow rate, pressure, and jet performance. These impellers are sold individually to fit specific Sta-Rite models (jet and circulation series), allowing targeted repairs for weak flow, cavitation, or impeller damage without replacing the entire pump assembly.

This category offers replacement Sta-Rite (BWG) impellers, compatible with popular Sta-Rite/BWG pump series (e.g., Max-E-Pro, SuperMax, WhisperFlo, and circulation models). Impellers are keyed or threaded shaft fits, high-flow (for strong jets) or low-flow (for circulation), and made from durable noryl/composite material.

Sta-Rite (BWG) impellers vary by pump series/model (Max-E-Pro, SuperMax, WhisperFlo, etc.), horsepower rating (0.5HP–5HP), shaft type (threaded or keyed), flow style (high-flow vs. low-flow), and wet-end compatibility—precise matching ensures correct GPM output, no cavitation, and proper fit inside the volute/diffuser.

Common problems include weak jets from worn or damaged impellers, cavitation/noise from cracked blades or mismatched size, restricted flow from scale/mineral buildup on impeller vanes, or complete pump failure from a broken impeller. Replacing the impeller is a cost-effective fix—often requires pump disassembly and reassembly with new seals.

To select the right Sta-Rite (BWG) impeller:
- Identify your spa brand/model, year, pump brand/model (e.g., Sta-Rite Max-E-Pro, SuperMax), horsepower/speed, wet end type, shaft type (threaded/keyed), and any markings on the existing impeller.
- Note symptoms (weak/no jet flow, cavitation noise, vibration, pump overheating), or visible impeller damage (cracks, worn vanes, scale).
- Avoid guessing—send us clear photos of the pump wet end (showing impeller blades/vanes, shaft type, volute/diffuser opening, pump label/model, and spa label with model/serial number) for expert verification.
