Without specific Komatsu product documentation, it's difficult to determine the exact displacement value precisely. However, for hydraulic main pumps used in compact excavators like the Komatsu PC35MR-2 and PC35, the displacement is likely to be in the range of 30 to 80 cubic centimeters per revolution (cm³/rev). A displacement in this range is suitable for powering the relatively smaller hydraulic actuators in these excavators, such as those for boom lifting, arm movement, and bucket operation.
Operating Pressure
These pumps are designed to operate at pressures appropriate for the hydraulic systems of the PC35MR-2 and PC35 excavators. The maximum operating pressure is likely to be in the range of 200 bar (20 MPa) to 300 bar (30 MPa). This pressure range is sufficient to drive the hydraulic cylinders and motors that perform the various tasks of the excavators, such as digging in different soil conditions and lifting loads. The exact maximum operating pressure should be confirmed from Komatsu's official specifications for the 708-1T-00520 pump.
