My pump on my boiler is leaking at the cartridge seal. I have had it apart a few times and everything looks good. No nicks in the seal no pits in the casting ect? Do they just sell the cartdrige seal?
Thank you,
Rob

For example: That circ, connected to a 1" pex loop of 200' in length is going to be at the top of it's curve developing about 25-26 ft of head and around 10GPM. It's not going to live long operating in that range.
The only way to fix it is to buy a new cartridge. The seal is not available as a separate piece.

Will the wilo or grund direct fit into my taco flanges? As to the guy who sold me the 1" pex I am sure he sells it the same way today I even asked him many times if it would be big enough and he said "yep" to over come the head pressure we just added a bigger pump!! UGH!! I heat my storage pretty good but always looking for a better way.

I think the 0013 is standard flange size but i would have to look it up. If it is then either of the two I mentioned will bolt up.

Hopefully, you have some "give" on one end of these flanges if this where your pex connects. The Taco & Grundfos are about a 1/4" different in lengths I believe, at least the 007 and 15-58's are. I have one Taco 007 on the primary loop in my setup that was my first circ back when I just heated the pole barn with a simple heater tied right to the boiler loop. Everything I've bought since then is the 3 speed Grundfos 15-58s for my hybrid primary-secondary (ie. circ intensive) setup. I wish they were all 15-58s but I couldn't see not making use of the 007 I already had. Now since the 007 is connected to black iron, I will probably need to stick to the 007s or the newer Taco 3 speed version if it ever fails. FWIW, I believe the Taco 007 and Grundfos 15-58 flanges are interchangeable, though not sure about the 013. You could probably check website to see if 007 and 013 are different. I had a set of Taco green 1" flanges that I thought of reusing on a Grundfos but decided against since the local plumbing supply house sells red B&G ones for $6 apiece that match color better on the 15-58s. Wife already says I hope we never have to sell our house when she's down in the utility part of the basement and my plumbing job actually looks fairly decent.
in hot water said:you need to move about 17 gpm through that boiler to move 175,000 btu/hr. I doubt that a smaller circ will move near enough through that much tube (pressure drop) that larger pump was suggested to compensate for the small tube size. To move that much energy with a low head circ you would need 1-1/2" pipe or equivalent.
Remember 1" pex is a much smaller ID compared to copper or steel pipe.

in hot water said:sure, in parallel would double the flow, in series almost doubles the head, a bit of pressure loss through the second series is all. Here is what it looks like in series. I like to see a short piece of pipe between them to allow any turbulance to sort out, but flange to flange is used also.

If you say I need to move 17gpm thru the boiler whats my best setup for a 300' round trip thru 1" pex? Should I be looking for gpm or a pump that pumps more head pressure? As you can tell I dont have a clue about pumps I just know I got screwed on 1" pex and would like to make my system work the best with what i have.
I run my eko 60 like a eko 40 with only 1 fan and 1 nozzle I have 1000 gal storage closed system.
Thank you,
Rob
