Confirm your pump is an LX 48-frame model — check the label on the pump housing
Verify pump horsepower rating is 1.5HP before ordering
Measure the suction lip diameter (should be 3") and impeller outer diameter (should be 3-3/4") on your existing impeller
Inspect the existing impeller for wear scoring on the volute — a damaged volute may also need replacement
Confirm the pump seal and diffuser are in good condition before reinstalling — replace if worn
