Pression nominale: The rated pressure of this pump assembly is typically around 320 – 380 bar (32 – 38 MPA). This pressure rating is crucial for effectively driving the various hydraulic actuators in the E966H and E972H excavators, ensuring smooth and powerful operation of functions like lifting heavy loads and performing precise digging tasks.

Pression maximale: The maximum pressure that the pump assembly can withstand for short periods is usually higher than the rated pressure, atteignant souvent jusqu'à 420 bar (42 MPA) ou plus. Cette capacité de pression supplémentaire permet à la pompe de gérer des situations soudaines de charge élevée pouvant survenir pendant le fonctionnement de la pelle., such as when working in tough terrains or with hard materials.
