Rated Pressure: The rated pressure of this pump is usually around 350 – 400 bar (35 – 40 MPa). This pressure rating is necessary to effectively drive the various hydraulic actuators in the Komatsu D475, ensuring smooth and powerful operation of the bulldozer's working mechanisms.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure, often reaching up to 450 bar (45 MPa) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during heavy-duty operation, such as when pushing through tough soil or rocks.
