Interesting pump technology (no moving parts)

bobkoure · 02-11-2005, 09:12 AM

I ran into this electro-osmotic pump and thought it might be of interest here. Probably old news, and given that it relies on micro-pores through a disc of glass, which could be easily clogged, we'll probably never see it in PC water cooling.

but I think they have already raised $5M, some great big #

I think it was discussed before. It has low flow, which is too bad for us. I don't know what pressure it develops.

Pressure is ~2 to 10 bar for standard EO pumps (Standford pump -> ~40 mL/min), the most powerful develop ~500 bar (but very low flow). Useful for real micro, transitional and nanochannels.
