What you have are standard ANSI flanges on your domestic (US) valves and fittings. You can purchase ANSI/DIN flange adapters that have a relatively short takeout to remedy this issue. This will preclude any warranty voidances and, unless you simply have no space, make for an easy install. I have included a web link for your convenience, if you need further information please feel free to contact me at your leisure. http://catalog.ktronpremier.com/viewitems/flow-transition-adapters/round-aerolock-flange-to-din-ansi-flange-adapters

Well that's all fine and dandy but the old configuration couldn't support more than we did. So we have to bolt it directly on the pump. Not the best scenario. It "could" have been done but would be out of scope and trying to get it in scope is nearly impossible. We went off the AHJs engineering feasibility study, where they missed it. >From the AHJ, not Turkmenistan, said it needs to be "good enough" lol. So it >won't meet some things in 20, they know that. Heres the pump setup. 3 electic pumps in parallel, 2 on city power and 1 on generator. All Wilo brand, panels are not designed for automatic operation. So if the system goes off they have to run down and turn them on. Also the generator is not automatic, so if power goes out they have to run down and turn it on. The pump are horizontal going in and vertical out, the correct term for this style is alluding me at this moment. Everything about this project stinks but it only has to be "good enough". Probably will have to drill the valve and void the listing. Material needs to be procured in the states and shipped. The survey team missed the PN16 flange. Just sent Class 150 flanged. We'll approve the voiding of the listing from the local AHJ representative and proceed. Luckily though the victaulic groove flange adapters have slotted bolt holes designed for it. Aaron M.
