i am in need of some peristaltic pumps for a project (or 2!) and of course the first place i looked was Adafruit and picked up one of their small pumps (https://www.adafruit.com/product/1150) but 100ml/minute is nice for some applications - however I now need some higher flow pumps - 500ml/minute would be good.
In Sweden I have found it hard to find anything really until recently when Amazon.se opened up - now there are a few options around (though prices start to climb rapidly!) - it seems the most common variant that suits my needs is a 12v “G928” (https://www.amazon.se/s?k=g928+pump&ref=nb_sb_noss) which has many sellers - they all appear to come from the same factory.
im normally happy to pay a premium to someone like Adafruit (as a hobbyist) and have them take the risk of screening suppliers, ensuring compliance to RoHS etc - so my question is if someone has any advice on how to screen companies like this and it might be amazon, alibaba, ebay… whatever; places where its easy to sell things of potentially questionable origin and quality.
(for some parts I am less concerned than others, however one project for these pumps is a food project with my kids, so im much more concerned about quality)
i might be being overly cautious, but in the off chance im not…
