I would also be interested in the information sought below along with the
following additional questions (to compare the designs being developed here
with what is available) :
(a) What are the pressures the pump generates at the low end of the flow
(ul/min)

(b) How well does tje pump respond when it is used to pull liquids (suction
pump) and how large a pressure drop would it handle.

We looked at the IMM pump and there is insuffcient technical information
for us to make an evaluation.
