Presiune de funcționare

Presiune nominală: Generally, the rated pressure for these pumps is around 200 – 250 bar (20 – 25 MPA). This pressure is suitable for powering the hydraulic systems of mini excavators, enabling smooth operation of functions like arm movement, Funcționare cu găleată, and machine rotation.

Presiune maximă: The maximum pressure that these pumps can withstand for short periods is usually higher, reaching up to 300 bar (30 MPA) sau mai mult. This additional pressure capacity allows the pumps to handle sudden high-load situations during the mini excavator's operation, such as when working in tougher soil conditions.
