Rated Pressure: These pumps are designed to operate at high pressures to meet the demanding requirements of the PC1250-8 excavator's hydraulic system. The rated pressure is likely to be in the range of 300 bar (30 MPa) to 350 bar (35 MPa). This pressure range enables the pump to provide stable and sufficient power to drive various hydraulic actuators, ensuring smooth and efficient operation of the excavator.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure. It may reach around 380 bar (38 MPa) to 420 bar (42 MPa). This allows the pump to handle sudden high-load situations that may occur during the excavator's operation, such as when encountering hard rock or other significant resistance.
