Description
Replacement 3.5 Horse Power Impeller designed specifically for 56 Frame Pump Wet Ends made by Intertek LX Brand. This impeller is compatible with pumps displaying part numbers WUA-350, WP-350, or LP-350 on their identification label.
CRITICAL MEASUREMENTS: This impeller measures approximately 4 23/64 inches across the face from edge to edge, roughly 3 inches from the front tip to the back sleeve tip, and 3/8 inch from the inside vane edge to edge. These precise dimensions ensure proper fit and performance in your spa pump assembly.
IMPORTANT IDENTIFICATION NOTES: Some impellers feature the marking B351-21. If yours displays this number, you must verify the overall width measurement edge to edge before ordering. The manufacturer produces one casting with this number and machines it down to accommodate different horsepower ratings, making accurate measurement essential for correct fitment.
COMPATIBILITY WARNING: While this wet end assembly may visually resemble Aqua-Flo and CMP wet ends, these components are NOT interchangeable. Always confirm your pump manufacturer is Intertek LX Brand before purchasing to avoid compatibility issues and ensure optimal spa circulation system performance.
