6 QuestionsQ: What is the warranty on this pump?

Verified Reply- SupplyHouse StaffThe warranty on this pump is 3 years.
Q: Can the impeller be changed on this unit? Is there a parts break out of this unit?
Asked by TPS 12 years ago
Add your answer
I don't think that replacement parts are available for this particular pump.
No, You can't change the impeller because you can't find anyone that sells parts for this pump. Pretty reliable little pump but not serviceable. You have to go to the bigger pumps to get parts for them. I have one as a backup.
Not sure about, but if you contact manufacture, they could let you know. If unit has much use on it, I would just replace entire assembly. Sent from my iPad
While anything can break (enter my grandkids) my pump has run 180-degree water nonstop for four years straight without a hitch. Most of the time it has been on medium but recently I've turned it up to high to measure the wood consumption in my outdoor boiler (my thinking is it will burn less, which so far appears to be the case). I don't remember a parts diagram but there could have been. Hope this helps. --Mark
Q: i have a boiler system from the early 1940's. It has 4 zones with 4 B&G pumps with a serial number MOT-6-3-H. I need to replace them with newer circulator pumps. 2 units will be pumping to upstairs apartments and i estimate the head at around 15'. for the 2 lower apartments i am looking at NFR-25's and the NFR-36 on the uppers. does this sound correct or do you recommend a different set up?

I think it would work, but I would contact the manufacture of the pump with what you have now & ask for their recommendations. Sent from my iPad
Q: is this pump a good replacement for the discontinued slc-25 that is making a lot of noise at the boiler.

Verified Reply- PexSupply StaffThe NRF-22 circulator (part 103251) is the recommended replacement for the obsolete SLC25.
Q: Will Taco flanges on my boiler work with this pump?
Asked by Gary 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, this pump works with standard flanges.
Yes, this pump definitely works with Taco flanges.
Taco and others make a variety of flanges, so this will be a generic answer. Yes, they will work, however you may need to rotate them 90 degrees to match the flange orientation of this casting vs. the original Taco pump flange orientation. Rotating the flanges if they are soldered in place and the flange plate itself is fixed relative to the flange central body can require a level of technical skill that may prove to be a challenge. I was able to solve this issue just this weekend on a job with a couple of 3/4" Sharkbite couplings on either side of the pump piping. I just cut the copper, installed the couplings and then rotated the flange to be correct for the new pump. Of course, this approach requires supporting the pump somehow so it's own weight doesn't cause the pump motor body to rotate out of the horizontal plane. B&G supplies square cut seal rings with it's pumps, however, they don't supply flange bolts, so you'll need to reuse the ones that were there. Good luck!
Q: Hi, I'm not getting good enough circulation with a NRF 22 circulator pump. Will the NRF 36 drop in to replace the NRF 22 without changing plumbing? Thanks

Verified Reply- PexSupply StaffThey have the same flange-to-flange dimensions, so you will not need to repipe the system.
