Circulator replacement

Good afternoon,

I'm working on a instruct swap out and cannot locate another 005-f2 Circulator pump. Would a 007 e or a regular 007 work? Thanks in advance.

Another question I have that's related to the job, this is a old steam system that was converted to hydronic, I am trying not to drain the system fully do so this job because I fear it will be a nightmare to purge all the air. Has anyone had an issue purging air from systems like this? Any tips?

I am hoping a jet swet may fit into the 3/4 nipple attached to the flange and I may be able to swap out the old flange and close it with a valved flange with out draining the system. I can isolate the supply but not the return.

    Your uploaded files are not able to open. Are these files stored on your computer? You need to use a different method to put them on the site so we can see them.

    The problem with having a valve on one side of a loop and not the other side makes it impossible to open the system without draining the water above the point where you want to do the work.

    As you can see from this Performance chart, the 005 has a similar curve as the 007. it falls just below the 007 performance curve, that said the 007 would be able to do the job that the discontinued 005 pump can do.

    After you make that expensive repair and you still have the same problem, What will you check next?

    Thank you for the reply. I'm uploading it from my phone and I'm not sure why it's not working.

    I'm trying to avoid draining the system, have you ever used a tool similar to a jet swet to plug the hole to avoid draining the system?

    the pictures seem to be working now.

    kinda hard to tell for your pictures but it looks like a gravity hot water system that was converted to pumped.

    The jet sweat should work although you're going to make a mess getting it in there.

    Yes ye, it was either gravity or steam prior to the conversion.

    I may just drain it and do my best to purge the air out.

    Might be better to drain it and add isolation valves and a magnetic dirt separator or wet rotor circulators aren't likely to last that long on that system.

    But do they work? Only one way to find out.

    You already have Isolation valves flanges. Have you tried to move them the the closed position? You may need a strong screw driver that will not slip out of the slot.

    i'd try a straight blade socket or an insert bit in a socket and ratchet so i could really push in while i tried to turn gently

    spray those screws first with penetrating oil. Some of those will take an Allen wrench in addition to the screwdriver

    Those will be tough to turn. Don't try it WITHOUT soaking them with PB Blaster, WD 40 or some penetrating petroleum based lubricant. Let them soak for many hours.

    Thanks for all the comments. I did not know that was a valve. I have only seen the newer style circ flanges with isolation valves. I am going to soak them before I try and open them.

    I will recommend the dirt separator as well, Thanks!

    OMG! seems like half the time I have ever turned those valves they started leaking sometimes profusely. Soak 'em up good!!

    The job went smooth. Thank you for all the help. The existing flange worked and held. You guys are great.

    Feel free to tear it apart 😄.
