              Replaced our original 3 speed oil lubricated circulator for our radiant heat system with this maintenance free pump and couldn't be happier. It is extremely quiet and other than re-plubming for the difference in voulet length, installation was a breeze.

                    This pump replaced a B&G Series 100 Pump with 8 Feet of Head Pressure and 33 GPM. I always had issues in where the return temperature was off by over 30-40 degrees and it took over an hour before the old pump had a difference of at least 25-30 degrees.

                    This pump (NRF-36) within 10 minutes at start up does the trick. It is used for radiant heating applications. Because of the head pressure and speed I was able to move the air out of the system without having to fast fill the system. Also it is a great pump if you are going to add extra zones for radiant in the future. This is all you need.

                          This pump is the one we always spec these days to deal with high head applications like Rinnai's and NTI boilers.
                          This and the NRF-25 have replaced 6 B&G pumps we used to have to stock, making inventory much simpler to maintain.
                          Only negative is that with B&G shifting manufacturing to China, their has been a bit more in-warranty return than in the past, but I assume this is just a quality control issue that B&G is aware of and will be addressing over time. Warranty return and credit has been no problem, regardless of supplier.
                          PexSupply.com has proven to have excellent pricing, delivery times and customer service support and has become our primary Hydronics supplier over the last year.

                                      We live in New Jersey in a typical colonial with a 30' head between the basement boiler pump and the baseboard radiators in the finished attic. This pump can circulate all floors. There is nothing better you can do to improve the efficacy and efficiency of circulated hot water heating than upgrade your pump.

                                          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.

                                          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.

                                        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?

                                          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!

                                          They have the same flange-to-flange dimensions, so you will not need to repipe the system.
