ELECTRIC MOTOR HORSEPOWER (HP) REQUIRED TO DRIVE A GIVEN HYDRAULIC PUMP
Use this equation to help figure out what electric motor horsepower (HP) is required to drive a hydraulic pump. SImply take the gallons per minute (GPM) multiplied by the pump pressure PSI then divide that number by the result of 1,714 times efficiency (we used 85% effiencey in this case).
NOT SURE WHAT YOUR GALLONS PER MINUTE (GPM) ARE?
Here are several equations/calculators that you can use to find missing variables that you need.
