Pentair SuperFlo VS vs Hayward MaxFlo VS

You are deciding between the two best-selling residential variable-speed pool pumps in the U.S. The Pentair SuperFlo VS and Hayward MaxFlo VS deliver near-identical electricity savings (75–85% versus a single-speed pump), but they differ on price, install fit, and warranty path. Here is the head-to-head, plus when to step up to the Pentair IntelliFlo VSF.

Which one is right for you?

Choose the Pentair SuperFlo VS if you want the most-installed VS replacement pump in the U.S. Installers know it cold, parts are easy to source, and the 115/230V auto-sensing means a drop-in swap on most existing equipment pads. Best when your current pump is Pentair (Whisperflo, SuperFlo single-speed) and you want a like-for-like upgrade. Choose the Hayward MaxFlo VS if your existing pump is Hayward (the Super II model number, or any Super Pump). The plumbing footprint matches and the swap is the simplest. The MaxFlo also runs slightly quieter at low RPM, which matters if your equipment pad is near a window or patio. The Doheny’s Amazon listing is sold by an authorized Hayward dealer; confirm at hayward.com’s dealer locator before purchase to keep the factory warranty intact. Consider the IntelliFlo VSF instead if you have a complex setup (solar heat, water features, an automatic cleaner) or you want true flow-rate control rather than RPM control. The IntelliFlo holds a target GPM as your filter loads up, which the SuperFlo and MaxFlo cannot do. Worth the price step-up only if you’ll actually use the flow-control features.

Frequently asked questions

How long do these pumps last?

Pentair SuperFlo VS and Hayward MaxFlo VS both target 8–10 years of service life when sized correctly and run on the variable-speed schedule (most hours at low RPM). Single-speed pumps typically last 5–8 years because the motor runs at full RPM 100% of the time. The IntelliFlo VSF, with its larger TEFC motor, often goes 10–12 years.

Will my pool installer accept a pump bought online?

Most independent pool service techs will install any pump you provide. The install labor is the same regardless of where the pump came from. Some authorized Pentair / Hayward dealers will only install pumps they sold themselves, because their factory warranty backstops the install. Ask before you buy. If you buy online, plan on $250–$500 for a separate install visit.

Are the warranty terms the same?

Both Pentair and Hayward offer a 2-year limited factory warranty on the pump body and 1-year on the motor, but only if you purchase from an authorized dealer. Amazon 3rd-party sellers (which is who is selling the SuperFlo VS and IntelliFlo VSF on Amazon) generally do not transfer the factory warranty. The Hayward MaxFlo VS listing on Amazon is sold by Doheny’s, which is an authorized dealer; confirm via the official Hayward dealer locator before purchase if warranty matters.

Which one is quietest?

At cruise speed (1,800 RPM, where the pump runs ~80% of its operating hours), all three are quieter than a refrigerator: typically 45–50 dB measured one meter away. The Hayward MaxFlo VS edges out the Pentair models by 3–5 dB at low RPM. At full speed (3,450 RPM, used briefly for backwashing or cleaning), all three are around 65–70 dB.

Do I need a new electrical panel for variable speed?

No. Variable-speed pumps draw less peak amperage than the single-speed pumps they replace, so your existing breaker is almost always already adequate. The SuperFlo VS auto-senses 115V or 230V, so most existing wiring works as-is. The MaxFlo VS ships wired for 230V (a 115V conversion kit is available). The IntelliFlo VSF requires 230V. If your current pump is on a 115V circuit and you want the IntelliFlo, factor in $200–$400 for an electrician to convert the circuit.
