Rated Pressure: The rated operating pressure of this pump is typically around 150 - 200 bar (15 - 20 MPa). As a fan pump responsible for driving the cooling fan to maintain proper temperatures of the engine and hydraulic systems, this pressure rating is sufficient to provide 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 requires increased fan speed for enhanced cooling.
