Bought these as the recommended flanges for a Grundfos circulation pump, but they are a different size that the pump. Flanges themselves are fine if you want that style flange, but not for the pump they were sold as going with.

They do their job perfectly! The quality of the product is top of the line. I'm using it to pair it with my Grundfos water pump and it fit perfectly and hasn't leaked at all. You can tell this product is going to last.

Gotta have one of these sets if you want the pump to pump water - - the pump does not have any connections on it - -someone figured out a long time ago that replacing the pump a few years later is a lot easier if you can leave the flanges in place screwed into the piping, slide the new pump onto them, and bolt it down. Industrial quality, as common with Grundfos.
