I think you would have frequency issue.
Eventhou you would adjust your voltage the pump would runs slower then it should.

One time I brought clock from US to Europe. We compensate for voltage but clock was always off.
That was because of frequency.

I think you would be better off getting pump that is design for your country.

The pump is rated 50/60 Hz at either voltage. Frequency would not be an issue.

If you bought the pump with expectations of it working at 220 and you received the wrong one why not return it for an exchange?

Shipping it back to Northern Brewer in Milwaukkee will cost $$$, probably more than buying a new pump (at least, were I to ship it there and then get a return). So if any of you guys are looking for a pump, let me know...

Well you never know. Have you contacted them about it? They might ship it back for free to be the "good guy business". To me it would be a matter of was it represented to me as being the right type or did I just pick the wrong pump. If they misrepresented what the pump would do I would be a bit miffed and expect some service even if I was in Europe. Otherwise it's my mistake my bad- ya know?

Or work a deal with someone going to France. Something like: bring me the right pump and I give you another one- guaranteed to work in the US.

The manual says that they're all 115/230V. http://www.marchpump.com/site/files/966/112197/382497/524067/Pump_Manual.pdf
It might be worth calling March to verify.

Even if you did need a transformer, in the power range you're looking at it wouldn't exactly break the bank. Just an example: http://amzn.com/B000MW83OG

You may be on to something there, but you have to know what motor they used.
