Rated Pressure: The rated pressure of these pumps is generally in the range of 280 - 350 bar (28 - 35 MPa). This pressure rating is essential to effectively power the various hydraulic actuators in the D31 and D51 bulldozers, ensuring smooth and efficient operation of the working equipment.
Maximum Pressure: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, often reaching up to 400 bar (40 MPa) or more. This extra pressure capacity allows the pumps to handle sudden high-load situations that may occur during heavy-duty pushing or ripping tasks.
