FREE Hydraulic Pump and Motor Pressure, Flow and Torque Calculator

I’ve had lots of fun creating this hydraulic pump and motor calculator! Unlike the other online calculators out there, this one allows you to select the inputs you want and then get the outputs needed. It has never been simpler to calculate a pump or motor.

Choose any three out of pressure, flow, torque, speed and displacement and this will give you the rest of the information you need. No more back solving to get an answer!
