Displacement: The nominal displacement of the Nachi PVD-15B-35BP-11G5-4621H pump is approximately 15 cm³ per revolution. This value is a key factor in determining the amount of hydraulic fluid the pump can deliver in a given time, which directly affects the speed and power of the hydraulic actuators in the Hitachi H36B excavator.
Operating Pressure
Rated Pressure: The rated pressure of the pump is typically 35 MPa. This is the pressure at which the pump is designed to operate continuously under normal working conditions to provide stable and reliable performance for the excavator's hydraulic system.
Maximum Pressure: The pump is capable of withstanding a maximum pressure of around 42 MPa. This higher pressure rating allows the pump to handle short-term peak loads and pressure surges that may occur during the excavator's operation, such as when digging in hard ground or performing heavy lifting tasks.
