I have a 4000 PSI Hydraulic pump and a 10 ton hydraulic cylinder from JD2 for my pipe bender.

The manual for the 10 ton cylinder does not mention the diameter of the cylinder so is there some type of standard used to determine what the max PSI would be to provide the max 10T of force? I would expect the diameter/area of the cylinder to be one of the specifications provided but it doesn't seem to be. I would expect if the area of the cylinder was 1 square inch, then ~20,000 PSI would be the max PSI to lift 10T. If the area was 2 square inches then ~10,000 PSI would be needed to lift 10T, etc.

I guess I'm wondering why they match a 4K PSI pump with a 10T cylinder, unless it just happens that the 10T cylinder is the best fit and maybe is only being used/needed as a <= ~4 TON (assuming the cyl area is ~2 sq/in).

It seems to me, bending 2" DOM with 1/4" wall tubing might need more than 4 tons so I'm wondering if the 4K PSI pump is enough, but I still don't know what PSI correlates with the 10T cylinder, etc.
