Dayton Impeller Compatibility

This Dayton impeller serves as a direct replacement component for specific Grainger pump models. It is intended for maintenance professionals and facility teams who need to restore flow performance on the listed equipment.

Fits Four Grainger Item Numbers

The impeller fits Grainger item numbers 4ZA40A, 4ZA41A, 1TMU7 and 1TMU8, allowing a single spare to cover multiple pump installations. Using the correct impeller avoids mismatched hydraulics and frees inventory space by reducing the number of unique parts kept on hand.
