Rated Pressure: The rated operating pressure of this pump is typically around 380 bar (38 MPa). This pressure rating is essential for effectively driving the various hydraulic actuators in the Komatsu D475. It enables smooth and powerful operation of functions like raising and lowering the bulldozer blade, tilting it, and operating the ripper attachment.
Maximum Pressure: The maximum pressure that the pump can withstand for short durations is 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 operations, such as when pushing through extremely hard soil or rocks.
