A10VO71 Excavator Pump Rexroth A10VO74 A10VO74DFLR 31R-VSC46N00 Piston Pump Hydraulic Pump | PartsDic®_Excavator Idraulics, Motore diesel, SKS idraulico

For A10VO71, the nominal displacement is 71 cm³/rev.

For A10VO74 and A10VO74DFLR 31R – VSC46N00, the nominal displacement is 74 cm³/rev. Since these are variable – displacement pumps, the actual displacement can be adjusted within a certain range according to the system requirements.

Operating Pressure

These pumps are typically designed to handle high – pressure applications. The maximum operating pressure can generally reach up to around 350 – 400 bar, but the exact value depends on the specific model and its design.

Speed

The pumps are designed to operate within a specific speed range. The maximum rotational speed can usually be several thousand revolutions per minute (RPM). Tuttavia, the actual speed limit is affected by factors such as the pressure, displacement setting, and the mechanical strength of the pump's components.
