Hello, I'm Joe@Sun-Pump.com
. I've read through this thread & maybe have a few answers.
The magnets are supposed to be food safe, they were certified as such by an Australian testing lab. To what standards I have no idea. Keep in mind these pumps are manufactured in China, where adulterating infant formula with melamine is OK if it turns a better profit.
The fittings are brass and are 1/2 NPT.
As far as restricting the flow, a valve after the pump would be the preferred method. The pump is not self priming, it needs to be below the level of the liquid to fill. I test each pump before I shipping with a wall wart from an old electric razor. Just about any 1 amp wart will work, or you can buy 12V power supplies on ebay cheaply. The suppliers in Hong Kong ship very quickly if you find a cheap one there.
I don't have the stainless type fittings nor do I intend to due to the quantity required to purchase & the very limited demand. The price has recently gone up at the manufacturer's insistence so you won't find them for $60 any more.
Not soliciting sales, just some information. I know zero about brewing, pretty good at the drinking end of the process though.
