This flange set fits the 110-V Grundfos Circular Pump.
This flange set is for UP/UPS 15 and 26 series pumps.
The gaskets seated snugly against the pump body with zero fuss, and the 4 bolts threaded in cleanly without any stripping. Took maybe ten minutes to swap out the old setup, and the GF 15/26 connection matched perfectly on my unit.
Bolts and nuts lined up perfectly with the pump flange threads, so the whole install took under ten minutes. The gaskets feel dense enough that I’m not worried about leaks come winter. Exactly what I needed for my UP series circulator.
The bolts and nuts lined up perfectly with my Grundfos UP series pump, so I didn't have to wrestle with anything during install. Having both gaskets included in the set meant no last-minute trip to the hardware store, which I really appreciated.
