Without specific Caterpillar product documentation, it's challenging to determine the exact displacement value. However, for hydraulic piston pumps used in Caterpillar loaders of the 416D and 424D class, the displacement usually falls within a range that caters to the loaders' hydraulic power requirements. It could typically be in the range of tens to a few hundred cubic centimeters per revolution (cm³/rev). A higher displacement value allows the pump to move more hydraulic fluid per revolution, which is essential for powering functions like bucket lifting, arm movement, and steering.
Operating Pressure
These pumps are engineered to handle significant pressures to support the various hydraulic operations of the loaders. The maximum operating pressure for the 180-9588/1809588 pump in the context of 416D and 424D loaders 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 the heavy-duty tasks of the loaders. The exact maximum operating pressure can be found in Caterpillar's official specifications for this particular pump model.
