Without specific product documentation from Dan Foss or John Deere, it's difficult to determine the exact displacement value. However, for hydraulic piston pumps used in excavators like the John Deere 872G, the displacement is a crucial parameter. It could typically range from 100 to 300 cubic centimeters per revolution (cm³/rev). A higher displacement enables the pump to deliver more hydraulic fluid per revolution, which is essential for powering functions such as boom lifting, arm extension, and bucket operation in the excavator.
Operating Pressure
These pumps are designed to operate at high pressures to meet the demanding requirements of excavator operations. The maximum operating pressure for the Dan Foss 872G hydraulic piston pump assembly (with model numbers 83041431 and AT457670) in the context of the John Deere 872G excavator is likely to be in the range of 250 bar (25 MPa) to 400 bar (40 MPa). This high pressure is necessary to drive the large hydraulic cylinders and motors that perform the heavy-duty tasks of the excavator.
