The exact displacement value for the 123-2235 CAT hydraulic pump is not directly provided by the part number. For Caterpillar E330B and 330B excavators, the displacement is likely to be in a range suitable for powering various hydraulic functions such as arm movement, bucket operation, and rotation. It could typically be in the range of 100 - 180 cubic centimeters per revolution (cm³/rev), but the precise value should be confirmed through Caterpillar's official product documentation.
Operating Pressure
Rated Pressure: The rated pressure of this pump is usually around 350 bar (35 MPa). This pressure rating is crucial for effectively driving the hydraulic actuators in the Caterpillar E330B and 330B excavators, enabling smooth operation of functions like lifting heavy loads, digging, and maneuvering.
Maximum Pressure: The maximum pressure that the pump can withstand for short periods is typically higher than the rated pressure, often reaching up to 420 bar (42 MPa) or more. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the excavator's operation, such as when working in difficult terrains or with tough materials.
