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 perfectly against the pump housing on my first try, and having both flanges plus the four bolts and nuts in one kit saved me a trip to the hardware store. Fit the 26 series without any fuss, and the threads on the bolts were clean enough to spin on by hand before tightening.
Bolts and nuts included in the set made swapping out my old flange on the Grundfos 15/26 a straightforward job. The gaskets look and feel solid, and the fit was snug without any wrestling.
The gaskets seated perfectly against my Grundfos pump body, so no fiddling with alignment during install. Bolts are sturdy enough to torque down without stripping, and the whole set took me maybe twenty minutes to swap.
