What are the commercially available mechanisms/devices that would allow
creation of very high levels of hydraulic pressure by human movement?
Bicycle type of mechanism is preferred.

Dead weight testers go over 100,000 psi, but are one-shot devices so no
good if you need much volume or a continuous flow.


I'm already familiar with the Enerpac product line. Anything goes to
higher levels?


Enerpac goes as high as 40,000 psi, how much do you want?
