Externet Posted July 12 Share Posted July 12 Greetings. Do you know of a hydraulic piston or piston-cylinder assembly that I can re-purpose instead of fabricate/re-invent the wheel ? Similar to brakes, much larger diameter, like 50 to 100 mm. To work in reciprocating motion, only about 50mm travel, ~<10 strokes per second, up to 5000 psi. (not with a seal for rotating shafts) It is to produce pulses of hydraulic pressure. Like a driven small engine using it as a hydraulics reciprocating compressor 🙄 -Images borrowed from the web- Link to comment Share on other sites More sharing options...

Perhaps you could flesh out the detail a bit more ? Also perhaps a diaphragm might have better sealing, response/recovery time than a piston. 2 inch displacement at 5000 psi, on a repetitive basis, is quite a tall order.
