This article provides cross-reference charts for matching a variable speed motor to your Pentair pool pump. Converting your single or dual speed Hayward pump to a variable speed motor not only makes sense, but it will also save you cents. Variable speed motors are super-efficient and incredibly durable machines that turn your old single speed into cutting-edge technology.
Reasons to upgrade your pump to Variable Speed.
- VS motors can save homeowners up to 80% on their pump operating costs
- A permanent magnet drivetrain increases the motor’s energy efficiency and durability but reduces heat and friction
- Totally Enclosed, Fan Cooled (TEFC) design protects the motor from dust, rain, and wildlife from damaging components
- Runs super quiet
