Hi! I was just trying to cross reference my ancient B&G circ pump that I used to have on my heating system: Info is as follows: "P-4-132-5-5", "125-1 1/4" "DD" . Some years ago I replaced same with a Taco cartridge circ pump, and I assume I cross referenced same correctly, but then again it's never safe to assume is it? I'm "second guessing" myself because now I have an all new boiler (Buderus) with a nice Grundfos circ pump on same (pumping away as Mr. Holohan taught us some years ago) and wanted to be sure all is up to specs...thanks for any info!
