[PSUBS-MAILIST] Seals

[Alan via Personal_Submersibles]

Anyone familiar with the opposed dual spring loaded lip seal for the separation
of two fluids?

It "seems" the ideal seal for an oil compensated thruster, where you are keeping water out & oil in.  Am trying to find the right type of seal to fit on a 10mm propeller shaft that will run at up to 3000 rpm. 250 psi max pressure.
