I wonder where that 3800psi is coming from. Maybe the absolute most the cylinder can handle?
Most gear pumps on splitters are 3000psi max.
Typical pressure relief is in the 2200-2400psi area.
That makes for about 23-25 tons.
Ratings like that need to be regulated. It's just as bad as the "6hp" vacuum cleaners somehow working on a 15amp max 120v line, max of roughly 2hp.
I just threw a gauge on my CL 40 ton inline between the pump and control valve. It maxed my 3,000psi gauge out at ~3,200 psi and was still climbing when I let off. I should probably back off on the relief some. LOL
