Looking for Metal Bellows Accumulator Manufacturer

[Shockdesigner331]

Hello all. I'm looking for a manufacturer of pressurized welded metal bellows accumulators (WMBA). A few years back I had found a company on the internet that had a catalog of stock WMBA's with different fluid capacities and precharge pressures. I can not locate it online anymore. Does anyone know of any such companies? I know there are companies out there that can custom make such accumulators, but I want the best solution...just cheaply, the closer to off the shelf the better.

More specifically, fluid displaced = 26in^3, precharge pressure = ?(VERY FLEXIBLE ON THIS)

Thanks.

Have you tried Google with "metal bellows"?
Plenty of hits.

I've tried metal bellows in a google search (Amongst many, many, other combinations) but the same few companies show up and they are the custom manufacturers. I know there was a company out there before that had catalog items, maybe i'll try some other search engines. Seems lately that google really likes to post patent information (which is relatively useless).

I rarely use Google when searching for suppliers. Try ThomasNet instead:

Check Pipingtech.com. The sell bellows for expansion joints but may not sell what you need.

From my standpoint (aerospace) there are only a few metal bellows suppliers. So your usage is more along the industrial use?

Our product line is split between the aerospace and civilian/industrial. We've used the custom metal bellows houses before with great success, however the costs involved with these houses exceed my limits on this civil job. I want metal bellows for the infinite life they provide as well as hermeticity, but have a lot of design space to fit in an unoptimized accumulator chosen "off the shelf".

I really wish I would have documented that companies name....

Monkeydog: what suppliers have you used? we've used belfab with lots of success.

I have used Senior Metal Bellows which has been bought and rebought several times. They have done good for me.
There are others I am aware of but do not have direct involvement, so cannot say first hand. But I can say, Flexible Metal Bellows, and Kinemotive Corp has aerospace experience.
