Рейтинг давления: The rated pressure of this pump is typically around 350 – 400 бар (35 – 40 MPa). This pressure rating is essential for effectively driving the various hydraulic actuators in the CAT D8N and D8R bulldozers, enabling smooth and powerful operation of functions like raising and lowering the bulldozer blade, tilting it, and operating the ripper attachment.

Максимальное давление: The maximum pressure that the pump can withstand for short periods is usually higher than the rated pressure, often reaching up to 450 бар (45 MPa) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during heavy-duty operations, such as when pushing through extremely hard soil or rocks.
