Customer-Facing Q&A

Q: Is this pump intended for residential pools?
A: This model is designed for commercial-duty applications. It may be used in residential settings only when properly engineered and matched to the system, but it’s typically selected for commercial flow and runtime requirements.

Q: Does this run on single-phase power?
A: No. This pump is three-phase and requires compatible electrical service.

Q: Can this replace my existing Pentair commercial bronze pump?
A: In many cases, yes—especially if you’re replacing the same series/model or matching the same horsepower, voltage, and phase. Always confirm exact electrical specs, plumbing alignment, and performance requirements before ordering.

Q: What does “200/208V” mean?
A: The motor is rated to operate on either 200V or 208V three-phase service, commonly found in commercial facilities.

Q: Is the 22.3A rating the actual power draw?
A: 22.3 amps is the rated amperage provided for this model. Actual draw can vary with load and system conditions—always follow local electrical code and verify breaker/wiring sizing with a qualified professional.

Important Notes

• Commercial pump installation should be handled by a qualified professional and must comply with local electrical and safety codes.

• Confirm phase (3-phase), voltage (200/208V), and hydraulic requirements (flow/head) before purchase.

• Proper suction/return plumbing, valves, and filtration sizing are critical for safe operation and pump longevity.
