Proper storage of your Ebara self-priming pump when it’s not in use is essential for maintaining its longevity, protecting it from environmental damage, and ensuring it operates effectively when you need it again. Improper storage can lead to corrosion, wear, leaks, or even mechanical failures when the pump is put back into service. Below is a detailed guide on how to store your Ebara self-priming pump properly when it’s not in use.

1. Clean the Pump Before Storage
Action: Clean the pump thoroughly before storing it, ensuring that no residual fluids, dirt, or debris remain inside.
Solution:

• Flush the Pump: Use clean water (or a cleaning solution appropriate for the pump’s application) to flush out any residual fluids or contaminants from the pump casing, impeller, and other internal components.
• Clean External Surfaces: Wipe down the external surfaces of the pump, including the motor housing, pipes, and connections, to remove dust, dirt, or buildup. Use a soft cloth and mild detergent if necessary.
• Dry the Pump: After cleaning, allow the pump to dry completely to prevent moisture from remaining inside the casing, which could lead to corrosion or rust.

2. Drain the Pump Completely
Action: Ensure the pump is completely drained of any remaining fluids to prevent corrosion, freezing, or contamination during storage.
Solution:

• Drain All Fluid: Remove any residual water or fluids from the pump casing, suction line, discharge line, and motor housing (if applicable).
• Use Drain Plugs: If the pump is equipped with drain plugs, open them to allow any remaining fluid to flow out.
• Inspect for Fluid Traps: Ensure that no fluid remains in areas like the impeller cavity, mechanical seals, or other internal components that could cause rust or corrosion.

3. Lubricate Moving Parts
Action: Proper lubrication is necessary to prevent rust, corrosion, and wear on moving parts during storage.
Solution:

• Apply Lubricant to Bearings and Seals: Lubricate the motor bearings, impeller shaft, and any other moving parts with the recommended lubricant (either grease or oil, depending on the manufacturer's specifications).
• Prevent Corrosion: Use a corrosion-inhibiting lubricant to coat internal metal components and prevent rusting, particularly in areas exposed to moisture or humid conditions.
• Lubricate Shaft Seals: If applicable, apply lubricant to shaft seals to prevent drying out and cracking during storage.

4. Protect the Pump from the Elements
Action: Store the pump in a dry, cool environment, protected from the elements to prevent damage caused by moisture, temperature extremes, or exposure to chemicals.
Solution:

• Indoor Storage: Store the pump in an indoor, climate-controlled space with proper ventilation to ensure the pump remains dry. Avoid storing it in areas prone to high humidity, moisture, or direct exposure to sunlight.
• Cover the Pump: If storing the pump outdoors or in an area with high dust or dirt, cover it with a protective tarp or dust cover to prevent contamination or environmental damage. Ensure the cover is breathable to avoid trapping moisture.
• Avoid Freezing Conditions: If the pump will be stored in an area that experiences freezing temperatures, ensure that all water has been drained from the pump and internal components. Freezing can damage seals, gaskets, and other critical parts.

5. Disconnect the Pump from Power Sources
Action: Disconnect the pump from electrical, water, and air sources to prevent unnecessary wear or potential electrical issues during storage.
Solution:

• Unplug the Pump: If the pump is electrically powered, ensure that it is disconnected from the power source and the electrical cables are safely stored.
• Disconnect Hoses and Pipes: Detach any suction and discharge hoses and pipe connections to prevent internal pressure or stress on the components while in storage.
• Ensure Ventilation: If the pump has an electric motor, ensure the motor is properly ventilated or stored in a dry area to avoid any moisture buildup that could damage electrical components.

6. Inspect for Damage or Wear Before Storing
Action: Before storing the pump, perform a thorough inspection to ensure that no damage or wear has occurred during use.
Solution:

• Check for Leaks or Cracks: Inspect all pump components (casing, seals, gaskets, and pipes) for cracks, leaks, or signs of wear. If any damage is found, repair or replace the part before storing the pump.
• Inspect the Motor: Check the motor for any signs of damage, unusual wear, or overheating. Ensure that it is in good working condition before storing it.
• Replace Worn Parts: Replace any worn or damaged parts, such as seals, gaskets, or bearings, to ensure that the pump will operate smoothly when put back into service.

7. Use a Protective Coating for Metal Parts
Action: Apply a protective coating or rust inhibitor to metal parts of the pump to protect against corrosion during storage.
Solution:

• Coat Metal Surfaces: Apply a thin layer of protective oil or rust inhibitor to any exposed metal surfaces, such as the pump casing, motor housing, and suction and discharge ports.
• Use Corrosion Inhibitors: If the pump is stored in a high-humidity environment, consider using a corrosion inhibitor to protect vulnerable parts from rust and oxidation.

8. Store the Pump in a Stable, Level Position
Action: Store the pump in a stable position to prevent stress or strain on the components during long-term storage.
Solution:

• Place on a Level Surface: Store the pump in an upright, stable position on a flat, level surface to ensure that the components are not under strain or pressure during storage.
• Support the Pump if Necessary: If the pump is large or heavy, use support blocks or cradles to keep it stable and prevent damage to the motor or other components.

9. Regularly Check the Pump During Storage
Action: Even if the pump is not in use, periodically check its condition to ensure that no issues have developed during storage.
Solution:

• Inspect the Pump: Every few months, visually inspect the pump for signs of moisture, corrosion, or wear. Check for any fluid leaks or changes in the environment that might affect the pump.
• Test the Pump: If feasible, run the pump periodically (e.g., once every 3–6 months) for a brief period to keep the internal components moving and to verify that everything is functioning properly.

10. Documentation for Storage
Action: Keep detailed records of the storage conditions and any maintenance or inspections performed on the pump.
Solution:

• Document Storage Conditions: Record the date of storage, environmental conditions, and any maintenance actions taken before storage.
• Track Component Replacements: If you replaced components, note down the part numbers, installation dates, and any issues discovered before storing the pump.

Properly storing your Ebara self-priming pump when it’s not in use is essential for ensuring its reliability and extending its service life. By following these steps, including cleaning, draining, lubricating, protecting from the elements, and regularly inspecting the pump, you can help prevent damage and ensure that the pump performs optimally when it’s put back into service. Taking the time to store the pump correctly and maintaining it during storage will result in fewer repairs, less downtime, and a longer lifespan for the pump. For more info contact Ebara Distributors or call us at +971 4 2522966.
