How to Carry out Anti-Corrosion Cleaning of Split Case Pump

Split case pumps are widely used in water supply, HVAC, and industrial applications due to their high efficiency and reliability. However, during continuous operation, the overcurrent components—especially the pump casing—are subject to wear and erosion caused by impeller friction, cavitation, and water flow. Regular maintenance and anti-corrosion cleaning are essential to extend service life and maintain peak performance of a split case pump.

1. Maintain Proper Cleanliness of Components

During the maintenance process of a horizontal split case pump, cleanliness standards vary depending on the component:

– Fittings require a higher level of cleaning than non-fittings.

– Moving (dynamic) parts should be cleaner than static parts.

– Precision components must meet the highest cleanliness requirements.

– Surfaces that are sprayed, plated, or bonded require extremely thorough cleaning.

Use different cleaning agents and methods depending on the type and sensitivity of the component to ensure optimal cleaning results.

2. Prevent Component Corrosion

After cleaning, components—especially fine parts—must be protected from corrosion. If the cleaned parts of the split case pump are not immediately reassembled, apply anti-rust solutions or take suitable rust prevention measures to avoid damage during storage.

3. Ensure Safe and Eco-Friendly Cleaning Practices

Select cleaning agents and procedures that are safe for operators and environmentally responsible:

– Avoid flammable or toxic substances that could harm health or pollute the environment.

– Follow local safety and environmental guidelines during the cleaning process.

Conclusion

Routine anti-corrosion cleaning of a split case pump is a critical part of preventive maintenance. By ensuring component cleanliness, preventing corrosion, and prioritizing safe cleaning practices, you can significantly improve the operational longevity and reliability of your split case pump.
