Pressione nominale: The rated pressure of this pump is typically around 350 – 400 bar (35 – 40 MPA). This pressure rating is essential for effectively driving the multiple hydraulic actuators in the Komatsu PC1250-7, ensuring smooth and powerful operation of functions such as moving the large boom, arm, and bucket, as well as operating additional heavy-duty attachments.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 450 bar (45 MPA) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the excavator's operation in tough working conditions, like when dealing with hard rocks or in large-scale excavation projects.
