Hydraulic Pump Efficiency Testing

What is meant by efficiency is the ratio between output and input and is expressed in percent (%). The difference between output and input due to the losses include leaks in the pump so that it will reduce the volume of output. Overall, kebocran can occur in hydraulic pumps, valves, actuators, and on each connector. So in this case the ...
