B&G 100 - Swap with Taco 007, 0010, or Grundfos Alpha?

I currently have a B&G 100 pump that’s making a lot of noise. Wondering if I can replace with a Taco 007 or if I need to get a 0010 or a Grundfos Alpha? Also how do I know if I need the model with an Integral Flow Check (IFC)? My setup is a burnham gas boiler and I have ~8 zones for heat. The defective pump is for a zone on the same floor (in the basement), specifically a single bedroom with two cast iron radiators a couple of rooms away from the boiler. Thanks!

    007 should be more than enough.

    Another 100, a few smaller b&gs, and 2 taco 007 when we put in hydro forced air

    You can go with the 110-24 ( 3 piece pump ), 0010-F3, or 007-F5 circ. pump.

    8n zone valves, or 8 pumps. If zone valves use a delta P circulator. I'd use an ECM regardless.

    007 is more than enough for that small need. You only need the B&G 100 if there is a large GPM needed. Only 2 radiators, you will not need the extra power of the B&G for that zone. As far as needing an IFC, you most likely do not. I believe that because your B&G 100 does not have an IFC and the zone works fine without it. (probably because there already is an external flow check on that zone somewhere)

    After you make that expensive repair and you still have the same problem, What will you check next?

    As per TACO when I got my B&G 100 replaced instead of fixed like they were suppose to, they said to use the 0010 to replace the 100. They got really "miffed" and said that they'd wish plumbers would quit replacing the 100 with the 007. The Winter after the replacement for the first time in 60 years, we froze.

    The 100 has a flat pump curve and the 0010 has a steeper curve. If you are zoning with zone valves, I would go with an ECM pump.

    A ECM delta P circ is best with multiple zone valves, worth the extra $ as it uses less electricity while adjusting to changing loads
