Rated Pressure: The rated pressure of this pump is typically around 350 – 400 Bar (35 – 40 MPa). This pressure rating is crucial for effectively driving the hydraulic actuators in the CAT excavators, enabling smooth operation of functions like lifting heavy loads, digging, and maneuvering.

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, such as when working in difficult terrains or with tough materials.
