Description
The diffuser sits in front of the impeller, inside the volute, and is held to the bracket by two small Allen screws. Artesian2, ArtesianPro and Artesian Classic pumps each use one.
Pick your pump series, then the size. The easiest check is to match the diffuser you're replacing: if yours is an XL, order an XL.
