About this impeller

The LX LP300 impeller is a precision-engineered replacement part for 3HP main pumps using the 56 frame standard found in many North American and European spa systems. This OEM-quality impeller features a 3-inch suction line connection and 4-13/16-inch outer diameter, designed to restore optimal water flow and pressure in your spa's circulation system.

Built to LX's exacting specifications, this impeller delivers the exact fit you need to get your spa running like new again. We guarantee proper fitment and back every purchase with our 1-year warranty, plus same-day shipping to get you back to soaking faster. Before installation, verify your pump's horsepower rating and frame size match the 3HP/56 frame specifications to ensure proper operation and prevent damage to your pump motor.

Before you buy — quick checklist

  • Confirm your pump model is the LX LP300 — check the label on the pump housing
  • Verify the pump is rated 3HP and uses a 56 frame motor
  • Measure the existing impeller's outer diameter (should be 4-13/16") before discarding the old part
  • Confirm suction port size is 3 inches
  • Inspect the diffuser, seal plate, and shaft seal while the pump is open — replace worn components at the same time to avoid a repeat teardown

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