Without specific Caterpillar product documentation, it's difficult to determine the exact displacement value precisely. However, for hydraulic piston pumps used in Caterpillar excavators like the E330D and E336DL, the displacement is an important parameter. It could typically range from 100 to 300 cubic centimeters per revolution (cm³/rev). A higher displacement value means the pump can move more hydraulic fluid per revolution, which is essential for powering functions such as boom lifting, arm articulation, and bucket operation in these excavators.
Operating Pressure
These pumps are designed to withstand high pressures to meet the demanding requirements of excavator operations. The maximum operating pressure for the 259-0815/2590815 pump in the context of the E330D and E336DL excavators 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 hydraulic cylinders and motors that perform tasks such as digging, lifting heavy loads, and precise positioning. The exact maximum operating pressure should be confirmed from Caterpillar's official specifications for this specific pump model.
