Question: Flanges are not included?
Document: Identical OEM quality item; great price; directly replaced original circulator in home heating system; easily installed by homeowner with simple tools.
I replaced it myself with ease in about 10 minutes and didn't have the hassle of driving to locate one and pick it up.Need I say more ?
I ordered this as a replacement for my existing water recirculating pump at home. Identical model was installed when house was built in 1998, so the first one lasted about 15 years of 24/7 continuous use. I was pleased to find the identical model number on Amazon from a couple of suppliers. Paid about $60. It was an exact fit for 1998 replacement, which was critical. Upon inspecting the OLD one I removed, it appeared the plastic propeller fins inside had broken.
I got this with pump without the manifold (my manifold is from the brass model NBR-22, I would advise not to get the cast iron ), It is just the motor and impeller. All I really needed was the impeller, but's its not available as a standalone part. However, the impeller on this pump is made of a different (harder) material than previous replacements. Maybe the impeller will last longer than  my past replacements (about 5 yrs. ).
I expect my new replacement to last another mere 15 years.
I don't know how long this type of pump should last--the old one (same make and brand) lasted for exactly 10 years before coming to a 'screaming' halt. I noticed in the installation that the instructions are generic for the Red Fox brand as well making me wonder if I wasted my money by paying a little bit more for the Bell & Gossett branded pump?? They look just alike and both made in China... Otherwise it seems to be running very well.
I BOUGHT THIS PUMP TO REPAIR MY BOILER  MYSELF IT WAS EASY TO INSTALL AND I USED YOUTUBE TO HELP ME INSTALL MY PUMP.I SAVED ALOT OF MONEY DOING IT MYSELF AND THE PUMP IS WORKING WELL.
