The original circulator on my Weil-McClain boiler failed and I let a local contractor replaced it (hey, it was mid-winter. I had no choice). The circulator the local contractor was very noisy and vibrated the entire boiler unit.
I looked up this as the OEM circulator for my boiler. I installed it today and I immediately found why the other replacement pump was so noisy: there were no sound isolating rubber o-rings!
This circulator comes with the sound isolation rings and the flange has a channel for the o-rings. It is so quiet I have to touch it to feel it it is running.
I will buy another one of these to have it ready if I ever have to replace the circulator again.
By the way, the description here says 1750 rpm, but the pump says 3250rpm.
