Before adding fluid to a hydraulic pump, it must be ensured that all system components are clean and free from contamination. Contamination within hydraulic systems can lead to reduced performance, increased wear and potential damage to pumps and other components. To ensure cleanliness, follow some of these steps: 1. Clean the work area: Start by cleaning the work area where you will be working on the hydraulic pump. Remove any debris, dust or dirt that may contaminate system components during fluid fill. 2. Clean tools and equipment: Make sure all tools and equipment used for pump installation and maintenance are clean. Wipe all tools with a clean cloth or use compressed air to remove any dirt or debris that may have accumulated. 3. Clean system components: Thoroughly clean all system components that will come into contact with hydraulic fluid, including reservoirs, hoses, fittings, and connections. Remove any dirt, debris or residue with a suitable cleaning solution and a lint-free cloth or brush. 4. Flushing the system: If the hydraulic system is being assembled for the first time or has been exposed to contaminants, it is recommended to flush the system with a suitable flushing fluid. Flushing helps remove any particles, rust or debris that may have accumulated during manufacturing, storage or shipping.

Replace or clean filters: If your hydraulic system includes filters, check and replace them if necessary. Filters help remove contaminants from hydraulic fluid and prevent them from circulating in the system. Make sure the filter is clean or replaced before proceeding. 6. Check the reservoir: Check the cleanliness of the reservoir. Make sure it is free of dirt, debris or any other foreign matter. If necessary, clean the reservoir before adding new fluid. 7. Use clean fluid: Make sure the hydraulic fluid added to the system is clean and meets the required specifications. Contaminated or expired fluids can introduce harmful particles or chemicals into the system, causing component damage or performance degradation. 8. Proper Fluid Handling: Handle hydraulic fluid with care to prevent contamination during filling. Use a clean container, funnel or pump designed for hydraulic oil. Avoid exposure to dirt, moisture or other contaminants. 9. Secure Connections: Make sure all connections and fittings are properly tightened and sealed to prevent fluid leakage or contamination during operation. 10. Clean hands and personal protective equipment (PPE): Before handling any system components or hydraulic fluid, make sure your hands are clean. Use gloves or other suitable personal protective equipment to protect skin from oil, dirt, or other substances. 11. Use Proper Fluid Storage and Handling: Store hydraulic fluid in clean and airtight containers to prevent contamination. Avoid using liquids that have been stored for long periods of time or have been exposed to unsuitable conditions. Follow proper fluid handling procedures to minimize the risk of contamination during transfer. 12. Verify cleanliness of fluid transfer equipment: If you use devices such as hoses, funnels, or pumps to transfer hydraulic fluid, make sure they are clean and free of any contamination. Clean and inspect equipment before use to prevent foreign matter from entering the system.

Remove air from the system: Before adding fluid, remove residual air from the hydraulic system. Bubbles can cause performance issues and cause erratic operation. Follow the manufacturer's guidelines for proper venting or purge procedures to ensure the system is clean and free of air. 14. Filter fluid: If necessary, pass hydraulic fluid through a filter before adding it to the system. This additional filtration step helps remove any residual contaminants or particles that may have been introduced during fluid transfer. 15. Monitor the cleanliness of the oil: regularly monitor the cleanliness of the hydraulic oil during operation. Implement a maintenance program that includes routine fluid analysis and regular filter changes to ensure continued cleanliness and optimal system performance. 16. Maintain Proper Housekeeping Practices: Implement good housekeeping practices in hydraulic system areas. Keep the area clean and free of debris, minimizing the entry of dust, debris, or other contaminants. Regularly inspect and clean system components as part of routine maintenance. 17. Clean sealing surfaces: Pay close attention to the sealing surfaces of system components such as pump connections, fittings, and valve seats. Make sure these surfaces are clean and free of dirt, debris or old sealing material. Clean or replace any damaged or worn seals before installation. 18. Use clean tools to add fluid: When adding hydraulic oil to the system, use clean special tools to prevent contamination. Avoid using tools that have been in contact with dirt, grease, or other substances that may introduce contamination into the fluid. 19. Use a filter cart: If you have one, use a filter cart when adding liquid to further remove any contaminants. A filter cart typically consists of a filter housing and a pump unit, which filters the fluid before it enters the system. This helps ensure clean fluid is being introduced into the hydraulic system.

Prevent the introduction of contaminants: During fluid addition, take precautions to prevent contaminants from entering the system. Avoid touching inside of hose or reservoir opening, and keep fluid containers tightly sealed when not in use. Use clean funnels or dedicated fluid transfer equipment to minimize the risk of contamination. 21. Purge the system before operation: After adding fluid to the hydraulic system, perform a system purge to remove any air or contaminants that may have been introduced during the fluid addition process. Follow the manufacturer's instructions for proper decontamination procedures to ensure the system is clean and functioning properly. 22. Regular Fluid Monitoring and Maintenance: Implement a regular fluid monitoring and maintenance program. This includes regular fluid analysis, changing filters, and following recommended fluid change intervals. Regular maintenance helps ensure continued cleanliness and peak performance of your hydraulic system. 23. Proper Disposal of Contaminated Fluids: Properly dispose of any contaminated fluids in accordance with local regulations. Avoid pouring contaminated liquid into the environment or mixing it with clean liquid. Follow proper disposal methods to prevent environmental contamination. By taking these additional steps, you can further improve the cleanliness of your hydraulic system before adding fluid. Optimum performance, reliability and longevity of hydraulic pumps and other system components are critical to keeping systems clean and free from contamination.
