December 3, 20232 yr Hello ya'll I've not posted much here, lurking more than anything and reading. I found these calculators that are handy for hydraulic press building; This one is good for determining tons from a cylinder. https://www.baumhydraulics.com/images/calculators/cyl_calc.htm This one is good for speed of travel depending on ram size and GPM. The GPM used should be the low pressure GPM of the pump i.e. 13/4 gpm pump is usually 13 gpm at <600 or so PSI. Once the pressure goes about 600 or so the low speed of 4 gpm kicks in. https://www.baumhydraulics.com/images/calculators/cyl_speed.htm This one is good for calculation of electric motor hp - this should be with the high pressure GPM, not the low pressure gpm for hp required. https://www.baumhydraulics.com/images/calculators/motor_calc.htm I hope these are of benefit to some folks Ken H>
