Pump Question

[GENECOP]

I burnt out a B&G NRF 22 pump, I searched the Internet trying to find out what part or parts actually fail, I could not find anything. I know they are only 60-70 dollars so most people just replace them..So I brought the pump into my shop, took it apart, and the interior looks pretty simple and bullet proof, everything turned freely and looked ok, so could the failure be the capacitor? I cut the old capacitor out and ordered a new one for $8. The pump got airbound I guess, I heard it whining and it got very hot, then it stopped running. Just curious...

I got a b&g vario. I think it was around 120 or so. It's an ecm pump that isn't automatic but infinitely variable, so you could literally dial it in if you had to. It might be more forgiving...I think it shuts itself down before damage occurs, theoretically.

Hi there, why don't you take advice from some professional guy near you. B&G has always the best hydronic components around.

If it overheated, it's toast. they're generally pretty tough, and if you can replace the capacitor and get it working why not?
I just replace them. but I'm a professional, it's gotta work when I leave, and for a long time after.
