Hugh I was thinking of using a design
that some of the navy ships use their fuel tanks are also ballast tank they use
a rubber bladder in the tank fuel inside and water outside could you do the
same a hydraulic pump a light oil as you pumped oil in it would force water out
and then the hydraulic pump would never see salt water, it’s just an idea I have
been kicking around Brian V. Ryder CONFIDENTIALITY NOTICE: This e-mail message, including any

[mailto:owner-personal_submersibles@psubs.org] On Behalf Of Hugh Fulton I am looking for a bronze gear pump or such
for pumping water in and out of the Variable buoyancy tank. Harold Le Tourneau project page states he
is using one and I have a hydraulic pump on the Comsub which uses one but looking
for a simple corrosion proof one that is good for about 250 psi. Does anyone have any suggestions or using
one and where to source. I was hoping for about 40 litres per
minute. Any comments on capacity chosen. The problem with the
hydraulic pump is that the rotors/gears are made from steel. Hugh
