I am interested in the CH70 Hydraulic hole punch. Which hydraulic pump do you recommend to power it with? How much volume of air and how much pressure does it need to operate?
Hello Bill. We will recommend you use Electric Hydraulic Pump Single Acting Solenoid Valve 10000 Psi 7l Oil Capacity. It needs 10000 Psi pressure.

What’s the capacity for stainless steel
The thickness of stainless steel plate and iron plate is the same, but stainless steel is more ductile and the mold will be easily damaged. If you want to punch a stainless steel plate, you must prepare some molds first.
