Product Overview

The Hayward MaxFlo VS 500 W3SP2303VSP is an energy-efficient variable-speed pool pump designed for residential in-ground pool applications. Built as part of Hayward’s MaxFlo pump family, this 1.65 HP pump delivers reliable circulation while giving pool owners more control over filtration, heating, sanitization, and daily water movement.

With variable-speed operation, the MaxFlo VS can run at lower speeds for routine filtration and higher speeds when additional flow is needed. This helps reduce energy use, lower operating noise, and provide more flexible pool system performance compared with many traditional single-speed pumps.

Efficient Variable-Speed Pool Circulation

The Hayward MaxFlo VS 500 is designed to help pool owners save energy without sacrificing dependable water circulation. Its variable-speed motor allows the pump to adjust performance based on pool needs, making it ideal for daily filtration, cleaning cycles, heater flow requirements, and general circulation.

For many pool owners, upgrading from a single-speed pump to a variable-speed model can significantly reduce operating costs while improving control over pump runtime and flow.

Built for Easy Upgrades

The MaxFlo VS is designed as a practical upgrade for many existing MaxFlo pump installations. Its compact design, familiar plumbing layout, and compatibility with common 1.5" and 2" pool plumbing make it a strong option for replacement projects.

The pump also includes user-friendly onboard digital controls, allowing pool owners or service technicians to program pump speed, runtime, and operating schedules.
