Conjunto principal hidráulico da bomba da máquina escavadora CAT 2928768 para Caterpillar E966H E972H | Partsdic®_excavator hidráulica, Motor a diesel, SKS hidráulico

Pressão nominal: 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.

Pressão máxima: The maximum pressure that the pump assembly can withstand for short periods is usually higher than the rated pressure, muitas vezes chegando até 420 bar (42 MPA) ou mais. Esta capacidade de pressão adicional permite que a bomba lide com situações repentinas de alta carga que podem ocorrer durante a operação da escavadeira, such as when working in tough terrains or with hard materials.
