3. General Notes

All parameters are theoretical values, excluding efficiency and tolerances, and actual performance may vary slightly depending on operating conditions and fluid type.
Recommended hydraulic fluids include petroleum-based hydraulic oil, synthetic phosphate ester, synthetic polyol ester, etc., with specific requirements varying by pump series and model.
Installation methods include flange mounting and foot mounting (for specific models), and shaft types can be selected according to application needs.
For detailed ordering codes, maintenance guidelines and safety precautions, please refer to the official Vickers hydraulic pump manual.
