Pression nominale: The rated operating pressure of this pump is typically around 280 – 320 bar (28 – 32 MPa). This pressure rating is designed to effectively drive the various hydraulic actuators in the Komatsu D37EX – 22, ensuring smooth operation of functions like lifting the bulldozer blade and performing other tasks.
Pression maximale: 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 operation of the bulldozer, such as when pushing through tough soil or in other challenging working conditions.
