Rated Pressure: The rated operating pressure of this pump is typically in the range of 350 - 400 bar (35 - 40 MPa). This pressure rating is essential for effectively driving the multiple and powerful hydraulic actuators in the PC1250-7 and PC1250-8 excavators. It ensures smooth and forceful operation of functions like 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 excavators' operation, such as when working in extremely tough soil or rocky terrain.
