small variable displacement pump

[subsearobot]

Hi all,
I am looking for a small (.5 cubic inche/ rev displacement) variable displacement piston pump.

3600 RPM, at 3300psi, synthetic hydraulic fluid, ISO32.

anyone familiar with a manufacturer and model that I might investigate? I am presently perusing catalogs from Parker, Oilgear, and Eaton. so far no dice, but if you have any leads there, I am all ears!

I don't know where you would find a pump that small for such a high pressure, but most of your pressure compensated piston pumps include a "max volume" stop option. I know the Parker, Oilgear, and Eaton all include that option. (Getting a smaller pump though would be more efficient).
