The Hayward MaxFlo VS 500 Variable-Speed Pump (W3SP2303VSP) brings efficient circulation to in-ground pools, built around a dual-voltage capable motor drive that makes it a straightforward upgrade from older single-speed and two-speed pumps.
Unique Features & Technology
-
TEFC (Totally Enclosed, Fan-Cooled) motor — a totally enclosed, fan-cooled design built for efficient variable-speed operation.
-
Adjustable speed range of 600–3450 RPM, with independently settable minimum and maximum allowed speeds to match your filtration and cleaning needs.
-
Intuitive control pad rotates to four positions directly on the pump, or can be removed and wall-mounted (optional wall-mount kit SPX3400DRKIT) up to 500 ft away.
-
Fully programmable 24-hour clock with up to 8 custom speed/timer functions and day-of-week scheduling, plus a digital display showing live power consumption in Watts and speed in RPM or % of full speed.
-
Quick Clean mode runs the pump at its maximum allowed speed for a default 60-minute cycle, extendable in increments for extra cleaning passes.
-
Flexible control — operates in standalone mode or integrates with Hayward automation, including OmniLogic, ProLogic, ECommand 4, OnCommand, OmniHub, S3 Omni, and OmniPL.
- Carries a WEF rating of 10.7 and is DOE Compliant. Hayward notes this pump family is engineered to provide meaningful energy savings versus single-speed pumps.

Pool Size & Application
The MaxFlo VS 500 is designed as a drop-in replacement for many medium-head single-speed and two-speed pumps up to 1.65 total HP, making it well suited to in-ground residential pools that need dependable variable-speed circulation.
System Integration
This pump can run independently on its own programmable schedule or connect to Hayward automation systems (OmniLogic, ProLogic, ECommand 4, OnCommand, OmniHub, S3 Omni, OmniPL) via a rated communication cable. It can also be controlled by third-party or non-Hayward automation through relay speed inputs, selecting from up to 8 programmed timer speeds.
Poolaroo Pro Tip
Before startup, fill the strainer housing with water to help the pump prime — it's self-priming, but priming can take several minutes, so give it time before assuming an issue. Never run the pump dry, since the mechanical shaft seal relies on water for cooling and lubrication. At season's end, follow Hayward's winterizing procedure: shut off power, remove the drain plugs, and gravity-drain the pump body fully before storing it dry.
