Micropump

[lilmantis]

Hello all, I want to build an automatic aquarium fertilizer and I want to use some piezo micro pumps. Can you suggest me some good supplier in Europe? Also some in depth info on how to properly use them, risks, etc. would be much appreciated. Thank you.

Don't know anything about piezo pumps, but I know something about aquarium dosing, and the standard way is a peristaltic pump.  Basically, it's a pump where the mechanics never touch the fluid and that can very finely control dosing, so while they tend to be a bit large, they are very well suited for a wide variety of chemicals in sensitive environments.

Thank you for the response. Do you have any idea if there are some piezo pumps for medical with long lifetime?

Medical mean normally Certified and Certified Stuff mean many €€€.

Someone is selling curiejet liquid pumps on ebay.
