Comments about 0012 Cast Iron Circulator (HV Equivalent), 1/8 HP:

the 0012 circ pump bolted right up to another brand of flange - took all of 10 minutes to install, not a single drop of leakage - flange seals worked perfectly - a strong running pump - and I love the fact that replacement cartidges are readily available - at tremendous savings over replacing the full pump next time


Worked great in our application.

Comments about 0012 Cast Iron Circulator (HV Equivalent), 1/8 HP:

We had a B&G HV older series bearing assembly out and we used this Taco HV to replace the entire assembly. The Taco installation was much quicker and the cost made this a no brainer. Just make sure it will fit in your application from flange to flange. There are less moving parts to go wrong with the Taco compared to piecing out a B&G. We're very happy with this product


just what we needed

Comments about 0012 Cast Iron Circulator (HV Equivalent), 1/8 HP:

This was a replacement for original pump in our boiler system. We saved a lot by buying from pexsupply and it is the same part that our HVAC service person would have brought to do the replacement. It's cast-iron and comes with the flanges and gaskets. Reliable company that warranties the part for 3 years.

    is stainless steel better than cast iron?
    Asked on 8/20/2012 by molly from Wilmington DE

    2 answers



      Cast iron is perfectly good for hot-water circulators. Stainless or
      bronze might be preferred for pumping potable water, but not for space
      heating systems.

      Answered on 8/20/2012 by Doug from Illinois


      Stainless steel is more corrosion-resistant, but this is irrelevant in closed-loop heating systems. Make sure to use a bronze or stainless steel circulator with domestic water or in an open-loop heating system.
