Rated Pressure: The rated pressure of this pump is typically in the range of 250 - 350 bar (25 - 35 MPa). This pressure rating is designed to provide sufficient hydraulic force to drive the various hydraulic components and systems in the Komatsu HM400-5, ensuring smooth and reliable operation of functions like the dump body lift mechanism.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 400 bar (40 MPa) or more. This extra pressure capacity allows the pump to handle sudden high-load situations, such as when quickly lifting a fully loaded dump body or during emergency braking operations (if applicable).
