I know nothing about this thread except, I have a pond pump with ceramic
shaft magnet, the magnet is in a plastic jacket btw, it is a 12mm
diameter magnet, about 22mm fan on the end, and produces a column of
water 10mm in diameter at about 1.5 meters.
was on sale at local fish pond place at 30ukp/60$
surely thats more than enough flow for an etchant?
