Thanks for the reply BillA. While the selection is certainly limited, I am coming up with some reasonable candidates. I have not called Iwaki (bigben2k) but the word from a distributor is that Little Giant doesn't make anything good for -40 that will fit my space req's (under 12" length). I do have a candidate from March (
www.marchpumps.com) with their 809HS in stainless steel as well as a possible from Finish Thompson (
www.finishthompson.com) with their KC5 in PVDF. Interestingly enough, FT stated they had never rated their pumps at the low end of the temperature scale but they would cut me a significant deal on a pump if I would "test" it for them. While I would want some clarification on where that would leave me should their pump fail, I told them I would keep the offer in mind...:>) I have about 4 more companies to contact that I think might have a good candidiate and I will certainly post here if I get any winners. Also, while I know most are not willing/able to pay for the kind of pump I am looking for, I am fortunately able to be a bit more "generous" with this project. I will keep everyone posted on what I find.
