About this spa pump

This 2.5 HP Ultimax spa pump delivers reliable two-speed operation for mid-size to large hot tubs requiring 230V power. Built by Balboa with a robust 56-frame motor design, this main circulation pump provides the perfect balance of energy efficiency and powerful water flow. The dual-speed functionality gives you quiet low-speed filtration cycles and high-speed jets when you want maximum hydrotherapy performance.

At Bubbles Supply, we guarantee this pump is an exact fit for your spa's existing plumbing configuration. Every Ultimax pump ships same-day from our Canadian warehouse and includes our comprehensive 1-year warranty for complete peace of mind. Our experienced team verifies compatibility to ensure you get the right replacement part the first time. Verify your current pump's voltage, horsepower, and frame specifications match before ordering to ensure proper installation and optimal performance.

Before you buy β€” quick checklist

  • Confirm your existing pump is rated 230V β€” this pump will not work on 115V systems
  • Match horsepower: verify the label on your old pump reads 2.5 HP
  • Confirm your motor frame is 56Y β€” a 48-frame pump will not bolt into a 56-frame bracket
  • Verify your plumbing union sizes match before disconnecting existing pump
  • Check that your spa controller supports a two-speed pump on this pump bay
  • Note the rotation direction and discharge orientation of your current pump before removal

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
