Rated Pressure: The rated pressure of this pump is typically around 150 - 200 bar (15 - 20 MPa). Since it is a fan pump and not directly involved in heavy-duty hydraulic operations like digging or lifting, this pressure rating is sufficient to drive the fan with the necessary force for efficient cooling.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 250 bar (25 MPa) or more. This additional pressure capacity allows the pump to handle sudden surges in load, such as when the excavator is operating under extreme conditions and the cooling system requires increased fan speed.
