Hi,

I realize that you folks look at your pumps under a
microscope and think in terms of nL and uW, but I was
wondering if anybody had any sources for slightly larger
pumps. I'm searching for a pump in the 10-1000uL/min range
for oceanographic applications. Hopefully it would be an off
the shelf pump and would ideally have the following
characteristics:

1) low power/low current, something <1W, 10-50mA.
2) long duration, the pump would only operate 5-10
minutes/hour but I'm looking for 6-12 month duration.
3) flow rates from 10-1000uL/min, hopefully reversible.
4) capable of being immersed in oil for underwater use at
high pressures.

I've looked at mini peristaltic, solenoid pumps, micro
syringe, osmotic, etc. but they all have problems either
with power, longevity, or lack of fluidic control. I did see
a web announcement from MEMStek in WA about a small diaphram
pump but as far as I can tell, they're no longer in
business. Anybody got any ideas? I'm not on the MEMS email
list so could you please email me at tchapin@mbari.org.

Thanks very much for your help,

Thomas
