Presiune nominală: Presiunea nominală a acestei pompe este de obicei în jur 350 – 400 bar (35 – 40 MPA). This pressure rating is crucial for effectively driving the multiple hydraulic actuators in the EX1900, ensuring smooth and powerful operation of functions such as moving the large boom, arm, and bucket, as well as operating additional attachments.

Presiune maximă: Presiunea maximă pe care pompa o poate rezista la perioade scurte este de obicei mai mare decât presiunea nominală, Adesea ajungând până la 450 bar (45 MPA) sau mai mult. This extra pressure capacity allows the pump to handle sudden extreme high-load situations that may occur during the excavator's operation in tough working conditions, like when dealing with hard rocks or in large-scale excavation projects.
