oem 374GC 374L Hydraulic Main Pump Replacement for CAT Excavator | Partsdic®_excavator hidráulica, Motor a diesel, SKS hidráulico

Pressão nominal: The rated operating pressure of this pump is typically around 350 – 400 bar (35 – 40 MPA). This high pressure rating is essential for the effective operation of the hydraulic cylinders and motors in the 374GC and 374L excavators. It provides the necessary force to perform demanding tasks with precision and power, such as excavating hard rock or handling extremely heavy loads.

Pressão máxima: A pressão máxima que a bomba pode suportar por curtos períodos é geralmente maior que a pressão nominal, often reaching up to 450 bar (45 MPA) or more. This additional pressure capacity allows the pump to handle sudden peak loads during the excavator's operation, such as when encountering unexpected resistance or when performing critical maneuvers, safeguarding the reliability and durability of the hydraulic system.
