The displacement of the 708 - 1W - 00450 hydraulic pump for the Komatsu HM400 - 5 is an important parameter. Without specific detailed data from the manufacturer, it is estimated that for a machine like the HM400 - 5 (an articulated dump truck), the displacement might typically be in the range of 100 - 180 cubic centimeters per revolution (cm³/rev). However, the exact value should be verified through Komatsu's official product literature or technical documentation.
Operating Pressure
Rated Pressure: The rated operating pressure of this pump is usually around 320 bar (32 MPa). This pressure level is designed to effectively drive the various hydraulic actuators in the Komatsu HM400 - 5, enabling functions such as the operation of the dump body lift and other hydraulic systems on the vehicle.
Maximum Pressure: The maximum pressure that the pump can endure for short durations is higher than the rated pressure, often reaching up to 380 bar (38 MPa). This additional pressure capacity allows the pump to handle sudden high - load situations that may occur during the operation of the HM400 - 5, such as when dealing with heavy loads or rough terrain.
