The displacement of this hydraulic pump is 50.5 cc/rev. Displacement refers to the volume of hydraulic fluid that the pump displaces per revolution of its shaft. A displacement of 50.5 cc/rev is suitable for the relatively compact and less - power - demanding operations of the Hitachi ZX40U - 2 mini - excavator. It ensures a sufficient flow of hydraulic fluid to drive the machine's hydraulic components at an appropriate rate.
Operating Pressure
Rated Pressure: The rated operating pressure of the PVK - 2B - 505 - CN - 4962D pump is [X] bar. This is the pressure at which the pump is designed to operate continuously under normal working conditions. At this pressure, the pump can maintain a stable and reliable flow of hydraulic fluid to power the excavator's functions effectively.
Maximum Pressure: The maximum pressure that the pump can endure is [Y] bar. This is the upper limit of pressure that the pump can handle during short - term peak loads. For example, when the ZX40U - 2 is engaged in tasks that require extra force, such as digging through tough soil or small rocks, the hydraulic system may experience momentary pressure surges, and the pump must be able to withstand these without failure.
