These pumps are designed to withstand high pressures to meet the demanding requirements of backhoe loader operations. The maximum operating pressure for the 1003259/100-3259 pump in the context of the 416B backhoe loader 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 such as excavation, material handling, and positioning. The exact maximum operating pressure can be found in Caterpillar's official specifications for this specific pump model.
