Operating Pressure

정격 압력: Generally, the rated pressure for these pumps is around 200 – 250 술집 (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.

최대 압력: The maximum pressure that these pumps can withstand for short periods is usually higher, reaching up to 300 술집 (30 MPA) 또는 그 이상. 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.
