Without specific Caterpillar product documentation, it's difficult to determine the exact displacement value. Generally, for hydraulic piston pumps used in Caterpillar backhoe loaders like the 420D, 430D, 432D, and 442D, the displacement is an important parameter. It could typically range from 40 to 200 cubic centimeters per revolution (cm³/rev). A higher displacement means the pump can move more hydraulic fluid per revolution, which is essential for powering functions such as boom lifting, bucket digging, and swing operations of the backhoe loaders.
Operating Pressure
These pumps are designed to operate at high pressures to meet the demands of backhoe loader operations. The maximum operating pressure for the 224-6369/2246369 pump in the context of the 420D, 430D, 432D, 442D backhoe loaders and the 3054 engine is likely to be in the range of 200 bar (20 MPa) to 350 bar (35 MPa). This high pressure is necessary to drive the hydraulic cylinders and motors that perform tasks like excavation, loading, and unloading.
