Pressione nominale: The rated pressure of these pumps is typically around 280 – 320 sbarra (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.
Pressione massima: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, spesso raggiungendo fino a 380 sbarra (38 MPA) o più. This additional pressure capacity allows the pumps to handle sudden high-load situations that may occur during the bulldozers' operazione, come quando si lavora in terreno duro o terreno roccioso.
