Rated Pressure: The rated pressure of this fan pump is generally in the range of 180 - 260 bar (18 - 26 MPa). This pressure rating is sufficient to drive the fan at the necessary speed for effective heat dissipation of the excavator's engine and hydraulic systems.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 300 bar (30 MPa) or more. This extra pressure capacity allows the pump to handle sudden increases in load, such as when the fan encounters debris or operates in extreme environmental conditions.
