I'm sure its more of a casting flaw issue, the impellers probably would not machine up perfectly true at standard size so they went an extra .010 to .015 to get them trued up. Nothing wrong with them as long as you don't mind running the undersized wear ring. It will work fine
Good call Slo , suspect this is very likely the case (although we're not a Berk oem) Contrary to what one might think ,due to variences in machinery and operators not everything comes out as planned (machining) Berk has likley "cleaned" these up and is offering them as a budget alternative for folks We remachine several Impellers a season to undersizes for various reasons , nothing wrong with this unless the undersize gets below .025 (IMO) That said if anyone needs and impeller and is to the piont where a few bucks makes the difference , give us a call we'll always "work" with you Guys Tom
