Operating Pressure

Рейтинг давления: Generally, the rated pressure for these pumps is around 200 – 250 бар (20 – 25 MPa). This pressure is suitable for powering the hydraulic systems of mini excavators, enabling smooth operation of functions like arm movement, bucket operation, and machine rotation.

Максимальное давление: The maximum pressure that these pumps can withstand for short periods is usually higher, reaching up to 300 бар (30 MPa) or more. 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.
