Here are some pics of what we're up to in the hackerspace! Currently rebuilding the kit and setting up a test system for these centrifugal pumps, which are magnetically driven and all-polypropylene (no rotating seal). Currently setting up the power electronics to try to do speed/flowrate control/ramping.

This design of pump connection is very common in the industrial-catering machine-design industry. 😁

This would be a source of reasonably-priced pumps, that are designed to be maintained.
