To properly repair and service Transfer Pump 3, ensuring optimal functionality and longevity.

❖ Analyze the Source of Noise: Based on the diagnostic results, determine whether the noise is due to issues like:

• Cavitation or improper suction.

• Worn-out bearings, seals, or shafts.

• Misalignment of pump and motor.

• Blockages or foreign material in the system.

• Electrical issues in the motor.

❖ Rectification Plan may include:

• Replacement of mechanical seals, motor bearings, 'O' rings, shaft sleeve, and bush bearing kit.

• Stator cleaning and motor shaft polishing.

• Acid washing of pump sides.

• Reinstallation of parts and pressure testing.

• Replacement and alignment of impeller bushes.

• Cleaning and refurbishment of the impeller chamber.

❖ Post Rectification work, System Calibration and Testing should be carried out:

• Reassembly: After repairs, reassemble the pump, ensuring all components are aligned and sealed properly. Operational Testing: Perform operational tests to ensure the pump is functioning within specified parameters (flow, pressure, vibration).

• Noise Reassessment: After reassembly and repair, run the pump under normal operating conditions to ensure that the noise has been eliminated or significantly reduced.

• Performance Monitoring: Monitor the pump for stability, noise levels, and overall performance.

❖ Safety and Compliance:

• Safety Protocols: Ensure all work is carried out following safety standards and regulations (e.g., lock-out/tag-out procedures, PPE).

• Compliance with Standards: The vendor will ensure that all repairs and components used are in compliance with industry standards and manufacturer guidelines.

• Risk Mitigation: Ensure no further damage is caused to the pump or surrounding systems during the repair process.

❖ Vendor Warranty and Support

• Warranty: Provide a warranty for the repaired components and work performed, typically covering a period of 6 months.

• Post-Repair Support: Offer support or follow-up visits if the problem persists or if any issues arise post-repair.
