Rated Pressure: The rated pressure of this pump is usually around 320 – 350 bar (32 – 35 MPa). This pressure rating enables the pump to effectively drive the hydraulic actuators in the Komatsu HM400-5, ensuring smooth operation of functions like raising and lowering the dump body, as well as other hydraulic operations related to the vehicle's functionality.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure, often reaching up to 400 bar (40 MPa) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the operation of the Komatsu HM400-5, such as when dealing with heavy loads or in challenging working conditions.
