getting to install a cb6048 found a good deal on 2 2400-50 pumps -they will be 100ft for each pump are they ok for this set up
-
They are probably way too big.
How much is the price?
-
100.00 each still in boxes -thinking of 2 new 011 for 350.00 thanks
-
You're looking at 4.9 amps for the 2400-50. Could burn up some savings pretty quickly.
Around 2 amps for the 0011. a 0015 (a common size used) is less than one amp.
How much flow do you actually need? What size piping?
-
1inch
-
And from what you said earlier it's 100' one way? What heat exchangers or heat load are you supplying water to? Trying to calculate what flow is needed. I would feel there isn't a one size fits all pump, and the pump you described sounds large for 1" pex.
-
yes it 100ft each way t house and shop -both water to air rads in furnaces -planning on added cast irons rads to shop-was thinking theres no warrany on 100.00 pumps -

There are new 3 speed 26-99 Grundfos on eBay right now for $153. Would beat an 0011.
You might could get by with a new 15-58 or B&G NRF-25 for less than $100. Depends on the CFM of the blowers you've got the coils in.
-
ok thanks for info will look into those pumps - if you guys recommend them they must be good will probably go that rount -thanks
-
I would go with Grundfos unless you prefer Taco for some reason.
15-58 may be large enough or 26-99 are about the same sizes as the 0015 (15-58) and 0011 (26-99)
-
200ft total loop of 1" is about at the top of the spectrum for a 15-58 with an exchanger to keep full flow. The B&G NRF-25 has just a bit more umph, but may be harder to source. If you can afford to lose a little flow, the 15-58 is cheap and sips electricity, should get you 5-6 GPM. If you need the full 7-8 GPM that 1" can carry, I recommend the Grundfos 26-99

thanks for all info -plan on ording 2 26-99 tomorrow -
