Hi folks,
Does anyone know where I might get a hydraulic hand pump suitable for use with water and capable of supplying a pressure of 200 bar? Preferably one which isn't exorbitantly expensive either. I know Rothenberger make this type of pump, but as far as I can see their range only goes up to 60 bar. Suggestions would be appreciated.
Best wishes,
Chris
If you could use oil rather than water, there are quite a few available. Smiths Industries made/make a small hand pump assembly for access platforms and the like, and there are others. I have a GA drawing of one somewhere and a contact phone number if you cannot find it on the web.
Hydraulic oil would work as well as water, and you wouldn't have corrosion issues in the pump and valves.

How about put a hand crank on one of these, you must have something like it over there.
Just out of interest; what's the application?

Testing the barrel of a spud gun before use :-D.

That beast just looks exceptionally expensive!

Thanks for the suggestions. I was hoping to use water, because although it presents a corrosion problem it's cheap and clean!
Best wishes,

I have no experience of this, so feel free to say I am daft. But as liquid is vritually incompressible you only need a very small volume to be pumped at high pressure to achieve your test (assuming no leaks). So if you could plug the system all bar the pressure gauge and a grease nipple, you could use a grease gun to apply quite a bit of pressure.
Just a thought.

An old pressure washer would probably be the ideal source for the pump components.
Electric spray guns, available for under £20, often give 1600-2000 psi. Not quite 200 bar, but close.

quick squint at screwfix says most pressure washers are 100 bar and a few are up to 150.
