Rated Pressure: The rated pressure of this pump is typically around 280 – 320 bar (28 – 32 MPa). This pressure rating is essential for effectively driving the various hydraulic actuators in the GD805 and GD825 graders, ensuring smooth and precise operation of functions like leveling the ground, shaping the road surface, and operating the ripper attachment (if equipped).
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 380 bar (38 MPa) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the graders' operation, such as when working on rough terrain or with heavy materials.
