Rated Speed: The rated speed of the pump is usually in the range of 1200 - 1800 rpm. Operating within this speed range ensures efficient operation of the pump, providing the necessary flow and pressure to the hydraulic system of the ZX27U-3 while keeping the wear and tear on the pump components within acceptable limits.
Maximum Speed: The maximum allowable speed is likely around 2000 - 2200 rpm. Continuous operation at the maximum speed may increase the wear on the pump and reduce its lifespan, so it is generally recommended to operate the pump within the rated speed range.
