I don't know if you can group all the black pumps together. I'm still waiting to hear from US Solar, but I was told that the black pumps from DG Shenpeng are not good for boiling temperature food use. I'm still waiting for a follow up response to see if they are food safe at lower temperatures. I'm wondering if recirculating mash in the 150-160 degree area is ok? I'll let you know about both if they get back to me.
Were?
I don't know what US Solar uses, but there are grades of stainless that are magnetic and food safe. What ever the case, I trust that he knows what he's talking about. It's your prerogative to choose not to.
Hmm this statement from "Mike" is coming from a guy whos distributing, rebranding and selling many different pumps from many different manufacturers overseas, He is selling and profiting from these right? Not to accuse anyone of anything but you cant blame a guy for taking that statement with a grain of salt... The distributor is often last to find out when the maker takes shortcuts for profit themselves...Im not sure which pump we are even referring to for sure since US solar sells/rebrands a lot of chinese brands of pumps it seems including the tan ones with the actual food grade coated magnets.. at least they are selling them with their name on them on ebay.
From what I've read previously here, none of the pump are FDA approved. At best they are made of materials that are FDA approved under very specific conditions.
Are you saying that you know for a fact the 400 series stainless would make a weak motor? It has the same attraction to magnetic forces as steel and is the stuff used to make induction ready cookware. Can you make a magnet from it? I don't know.
Not at all but I am trying to clear up what being said here with whats already been discovered by others here including myself to be untrue assumptions.
Funny that everything from cutlery to surgical instruments to, yes, valves and pumps are made with different 400 series stainless. You better get on their forums and tell them to stop.
I know all about it.... Just spent $80 on a kitchen knife for Christmas that requires hand washing because of it... and yes I have had them rust. With Cutley and surgical instruments its a tradeoff for a hardered grade of metal that will hold a better edge longer... but a knife is easy to clean and dry.
On the left is the clone. On the right the US Solar. Both have sat for over three weeks without being taken apart. Both magnets were still wet when I took them apart. If this rust buggy man you worry so much about were an issue it would have started to form by now.
Congratulations on the purchase. My (highly magnetic) inferior Cutco knives have been mishandled for almost 20 years and show no signs of rust or corrosion. Guess Im just lucky, but if your knives are rusting with normal use, you might want to get your money back.
All the magnetic induction cookware that I've seen is the same stainless top to bottom. The difference being that some have aluminum or copper clad bottoms to distribute the heat and they don't need special treatment to prevent rust.
