I presently have a Taco 011 in my system. I want to buy a back up pump and I'm thinking of going with a Bell & Gosett. My question is what Bell&Gosset is similar to the Taco 011? Are the flanges the same? Etc.

You can look up the wet rotor series at B&G to find a curve that fits your app or matches the eleven, but there isn't one. The closest is the pl-30 and the pl-36 is a lot more pump. About 5-7 times the electricity to. They are splits, twice the size. Taco and grundfos pretty much have the Wet market. Maybe you could do a thorough calculation to find exactly what u need

 Sprinter, these are the wet rotor B&G pumps, why don't you think they compare to Taco or Grundfos? Curious because I know you are a pump guy, thanks.

Their wet rotor series has a hi failure rate with the capacitor they use, then the motor/cartridge. Now their commercial line or split series is very good to excellent. But there eat electricity and obviously have much larger curves. The commercial line doesn't like cycling, but it loves to run 24/7.
Around here grundfos is king and taco a close second. Depends on wether your on the east side or west. Not many even carry B&G anymore, other than the commercial. The WR series isn't horrible,, it's just not our first or second choices. I'm personally a taco guy, but that's mostly because of where the curve chart hits the calculations the most.

 I am very familiar with the commercial B&G line, it's very prevalent up here at least in the past, Grundfos is making inroads now, we don't see as many Taco's, I work on the electrical end so I am not as familiar with the curves, have replaced many a B&G unit with the old spring coupler, not a fan of that system, sometimes it makes more sense to replace them then change to a wet rotor style though. It's a little different world in the smaller pumps like these boilers, I use Taco pumps on my system and have had good service.

Both the B&G PL30 and PL36 will use less power than a Taco 0011. They are very close to the same size as the Taco.
The B&G NRF36 is about the same size as the 0011 also.

Thanks for the info.

Now I can't comment on the pl-30, but the 36 uses way more electricity. I just replaced a 36 and it was burning 268 watts, and a 0011VDT in its place ran 78-149 watts at full speed. The 0011 fixed on the other greenhouse manifold ran 140-144 watts. I don't know about the NRF 36, that one I haven't come across. I seen in the link there, I don't have any info on the nerf 36 & 45. Were on my curve charts. Thanks for the link too.

As far as flange size the 30 & 36 will work, unless your piping has zero flex  and in a tight space. It is a larger booster pump. Also the grundfos 26-96 will work. Pricey.

Is this the main boiler pump? You could also just get a replacement cartridge for the taco. Super easy to swap out.

I will have to test a 0011 again. I thought the one I tested was drawing 210 watts.
I have a PL36 in my house right now and it is the same physical size between the flanges as the 0011 that used to be in there. (There is very little overall difference between the two.)
It uses about 170 watts and I tested it while restricting the flow and it bottomed out at 130 watts with it dead headed.

The NRF36 is a much cheaper pump since they are made in China now. I haven't tested the power draw on one but the label shows it uses 100 watts more than a Grundfos UPS26-99 which is the same size.

Sprinter is right about Grundfos 26-96 or 26-99, both have similar pump curves to the Taco 0011; also correct about $$$, but Grundfos curve and power consumption are a tad higher than taco.

The head in the system will effect the watts used as well. Same as if you have cryotek or additives that might change the density of fluid. I haven't tested two of the same circs in the same spot and seen the same watts either. Close but rarely identical. I think as with most things sold today, materials and product are getting cheaper in most product. I have some 30 year old tacos running and yet have replaced newer tacos on same house. Is it the zone, conditions or product??!???

I'm sure if you increased the head another way other than dead heading it would show more power used. I use a kill-o-watt meter to measure power consumption, it also has cost per hour, day, cycle for customers to see. When your selling them a more expensive circ, it makes it easier when they can actually see #'s.
