Thomas,

The pumps that MEMStek announced were developed by our research group
at the University of Washington.  You can obtain more information
about them at the following web site:
  http://lettuce.me.washington.edu/~micropump/

They meet your power and flow rate requirements, although you'll have
to explain more about the oil immersion, what pressures and liquids
you want to pump, etc.  Take a look at our web site and let us know if
we can be of help.

Thanks.

Nigel Sharma.
