Bronz Taco Pump

[jmarv]

Hi All i have home built corn boiler (open system) and my 005 bronz taco pump went out on sunday no parts.
so to keep my system up and running i installed a cast 007 taco all is good for now.
My question is can i leave the cast one in till spring? when i installed the pump i didnot install valves, so the next time i drain the sys i need to install valves
on each side of the pump.
I will repair the bronz pump and keep the cast one for a spair.

Thanks

i know lots of people with owb that run cast pumps year round. i dont see a problem unless you have some real harsh water conditions. do you have a way to check and treat your water in the system? that would be if your really worried.

The bronze pump would only be required for potable water. for hydronic heat it is a bonus.

I use soft well water and the guy across the street sells boiler treatment so he will test the water and give me the stuff to add.

maybe i will just leave the cast pump in the system

thanks

Some how ---- I always thought you had built a closed system --- Me Bad for assuming

Anyway the cast pump will be fine, especially if you watch the water ph and nitrate levels.

Nice to see ya still posting

005 sounds like a small circ for a heating system? Is it on a DHW hx or domestic water side?

Often times you can change just the motor power head and keep the bronze body. But I'm not sure about an 007/ 005 motor compatability.
