3. Supplementary Notes
-
All parameters are theoretical values, and actual performance may vary slightly due to installation conditions, fluid quality and ambient temperature.
-
Do not exceed the maximum pressure and speed limits during operation; for PVB90 series, the maximum pressure must not exceed 210 bar (3000 psi) when using anti-wear hydraulic oil to ensure the service life of the pump.
-
The pump is compatible with a variety of hydraulic fluids, and the operating pressure and shaft speed should be adjusted according to the selected fluid type to avoid component damage; pay attention to the maintenance of load sensing compensator, pressure compensator (CMC) and flanged main ports.
-
For detailed installation and maintenance guidelines, refer to the official Eaton Vickers technical manual (Document No.: i3295s) or the PVB90 series dedicated datasheet.
