Rated Pressure: The rated pressure of this hydraulic pump for the Caterpillar E330B and 330B is usually around 300 - 350 bar (30 - 35 MPa). This pressure rating enables the pump to drive the various hydraulic actuators in the excavator, such as the boom, arm, bucket cylinders, and swing motor, ensuring smooth and efficient operation.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure, reaching up to 400 bar (40 MPa) or more. This extra pressure capacity allows the pump to handle sudden high-load situations that may occur during heavy-duty excavation or when operating in challenging conditions.
