About this impeller

This 2.5HP impeller (part #6500-612) is designed specifically for Sundance Spas pumps equipped with LX 56 series motors. Featuring a 2" suction line connection and 4-5/16" outer diameter, this OEM-quality replacement delivers the precise flow characteristics your spa requires for optimal water circulation and jet performance.

At Bubbles Supply, we guarantee this impeller will fit your Sundance pump exactly as intended, backed by our comprehensive 1-year warranty. Most orders ship the same day, getting your spa back to full operation fast. Before installation, ensure your pump is completely drained and power is disconnected – proper torque specifications during reassembly are critical for preventing future seal damage and maintaining peak performance.

Common symptoms this part fixes

If your spa is showing any of these signs, this part is likely your fix:

  • Weak or no jet pressure despite pump running
  • Pump motor runs but water flow is significantly reduced
  • Impeller visibly cracked, chipped, or worn
  • Grinding or rattling noise from pump wet end
  • Pump cavitating or losing prime repeatedly
  • Spa jets underperforming after pump seal replacement

Before you buy — quick checklist

  • Confirm your existing pump uses an LX 56 series motor — check the motor label for frame size
  • Verify the 2" suction line (SL) connection matches your existing plumbing inlet
  • Measure the outer diameter of your current impeller to confirm 4-5/16" OD before ordering
  • Inspect the pump diffuser and volute housing for damage — a worn impeller often damages surrounding components
  • Check whether your pump is single-speed or two-speed, as impeller compatibility can vary
  • Note your pump's full part number from the label before ordering to confirm correct fitment

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