Vacuum systems for boilers: does anyone have an opinion good or bad on Liquid Ring Vacuum systems as opposed to "hurling tank" vacuum systems?

    Ahem - they both suck???

    But, of course, that's good when it comes to vacuum.

    I don't know the answer to your question.

    Locally, we used to have a lot of Nash Jones liquid ring pumps installed by a construction firm that really knew its business about industrial and commercial buildings (in Dayton, and Cincinnati and far away too). Of what I know, these pumps have mostly been replaced (because they got old) by Hoffman hurling tanks. Then, again of what I know, it seems to me the Hoffman units call for more repair quicker than the Nash did.

    Personally, I tend to think the jet type pump is more practical because its performance is not strictly bound by volumetric constraints. Also, maintenance is more in line with simple pump seals replacements which are common to any plumbing/piping work. On the other hand, the concept of the liquid ring is simply brilliant.

    What are you looking for? How big is your system? Any lift stations? Did you follow the thread a little while ago about a neat vacuum system?
