Rated Pressure: The rated pressure of these pumps is generally in the range of 250 - 320 bar (25 - 32 MPa). This pressure rating is necessary to effectively power the various hydraulic actuators in the mentioned excavators, ensuring smooth and efficient operation of functions such as boom lifting, arm movement, and bucket operation.
Maximum Pressure: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, often reaching up to 380 bar (38 MPa) or more. This extra pressure capacity allows the pumps to handle sudden high-load situations that may occur during excavation tasks, such as when dealing with hard soil or small rocks.
