I want to build a simple low vessel which will take the hot waste from my continuous stripper still and as it fills up, a pump will switch on to pump the dunder into a larger vessel for storage & re-use in my next fermentation. I need this intermediate low vessel, because the dunder outlet is on a gravity feed circa 400mm from ground level and I have to pump into a tall storage vessel.
I've found a reliable industrial quality float switch, whose body is made from aluminium/bronze alloy. It's rated up to 210°C, although my dunder won't be hotter than 80 to 90°C, so it's not particularly demanding for it.
I've been trying to find data on aluminium/bronze alloys but from what I can tell, it should be safe i.e. will not leach anything into my dunder. They do make a stainless steel version but they are on 4 weeks back order and are considerably more expensive. The guy from Mobrey doesn't see I'll need stainless steel and I'm thinking he's probably right. This post is just in case someone thinks I'm being a nobber! ;-)
Appreciate thoughts. Cheers
