The older plastic pump that used to come with the Uni brau system is not food grade. I found the manufacturer and ask them on Alibaba where they sell those pumps for $15 a piece they responded that it is not food grade and that they are mainly designed to be used as utility pond pumps. I mentioned this in a thread and a couple weeks later those pumps were no longer being sold by Brau.. you can still buy them on eBay though for $15-20 you would think a company like that wouldn't sell something that obviously might not be safe considering the plastic that they were made out of was never designed to be used 4 food grade applications at that temperature.
I just don't like it when people get taken advantage of. I edited my post above and explained my reasons for bringing it up. I feel it's a valid thing to mention.
I just came across this thread and being the owner of Brau Supply, allow me to introduce myself. I absolutely respect Augie's perspective that DIY is a valid option, and I'm happy to support that. However there have been untruthful statements made by Augie about us, and I'd like to address this particular one, and add in a comment about our new system.
1. Our old plastic pumps we sold were in fact food grade pumps that were rated to 100ºC. They are not the same $15 pumps sold on Alie Express. Believe it or not, there are several plastic pump manufacturers in China.
2. Our new V3 system has many good reasons for us to charge $1199. We are not using an Inkbird or an STC-1000 controller, but a controller that is similar in looks but has upgraded internals to handle the power of the brewing element. This controller is outfitted with a 30A Hongfa (Japanese) relay inside, and also we use a custom made temperature probe which is tri-clamp instead of the cheap probes used. Temperature sensing is more accurate than the STC-1000, and the reason we went away from the PID and EZboil for control was simplicity. I cannot overstate how important it is to use a simple controller, and it just makes things more enjoyable. There are lots of fantastic PID's out there that can maintain temperature accurately, but the challenge of programming, and the need to re-tune them every time you switch recipes is inconvenient. When brewing 120V there just isn't much overshoot, and tight control is possible with our new design. If in fact, you actually were to go part by part through our V3 build, you would see that you will spend more than $1200 to get the same (and by that I mean apples to apples comparisons, not substitutions). Our kettle is made of 5mm tri-clad bottom with 1.2mm thick walls. Yes, these are better quality than our competitors kettles, and adding tri-clamp ferrules makes them even more so. I can go on, but I'd rather you all read to the end of this post, and you all can feel free to email me through my site if you have any more questions.
Finally, Augie, this is a personal and public appeal to you to cut it out. We've never met, and I agree it seems you have an axe to grind with our company, yet you haven't taken the time to introduce yourself to me. I'm not sure if you realize that your negativity affects others, and that there are human beings behind all of the companies who are just trying to make a living. The people behind these brewing solutions aren't trying to rip people off, or 'take advantage of others' as you eloquently put it, but we're trying to make products to be consumed by people who want to spend the money and who appreciate good design. I'll say again, I understand your perspective of DIY, but trashing those who try and produce good solutions isn't the answer.
Defamation is a serious thing, it's ugly, and it hurts people and their business. I think you can rise above it Augie, and I hope after this it will stop. Instead of posting untruths, I encourage you to email me personally about anything you think I've done and allow me to personally rectify it. I'm sure you know how to find me, and I'll be sure to respond.
Peace,
Steven
