Rated Pressure: The rated pressure of these pumps is typically around 280 - 320 bar (28 - 32 MPa). This pressure rating is essential for effectively driving the various hydraulic actuators in the D31 and D51 bulldozers, ensuring smooth and powerful operation of functions like pushing soil, lifting the blade, and operating the ripper.
Maximum Pressure: The maximum pressure that the pumps 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 pumps to handle sudden high-load situations that may occur during the bulldozers' operation, such as when working in tough soil or rocky terrain.
