The working pressure of a hydraulic pump refers to the pressure of the oil output (or input) of the pump (or motor) during actual work, which is determined by the external load.
Rated pressure refers to the highest pressure that can be operated continuously according to the test standard under normal working conditions. Its size is limited by the life span. If the pump (or motor) is operated at a pressure exceeding the rated pressure, the life span of the pump (or motor) will be shorter than the designed life span. When the working pressure is greater than the rated pressure, it is called overload.
