Kuala Lumpur — EKG M&E Sdn Bhd has successfully completed a comprehensive mechanical overhaul of a primary fluid circulation pump. This project involved the precision replacement of motor bearings, pump bearings, and the mechanical seal—the three most critical components for ensuring leak-free operation and rotational stability in high-demand M&E systems.
In any centrifugal pump system, the bearings and mechanical seals are considered high-wear consumables. Over time, constant rotation leads to "fatigue" in the bearing races, resulting in increased vibration, heat, and eventual motor burnout. Simultaneously, a degraded mechanical seal can lead to fluid egress, which not only wastes water or coolant but can also damage the pump shaft and internal electrical components through moisture ingress.
Our mechanical team performed a full teardown and restoration of the pump assembly:
Motor & Pump Bearing Replacement: We removed the aged, high-friction bearings and replaced them with premium-grade, precision-matched units. New bearings ensure that the motor and pump shaft rotate with minimal resistance, directly reducing the energy required to move fluid through the system.
Mechanical Seal Installation: The old, compromised seal was replaced with a new high-durability mechanical seal. This ensures a watertight interface between the rotating shaft and the stationary pump housing, maintaining system pressure and preventing environmental contamination.
Shaft Alignment & Cleaning: While the unit was dismantled, our technicians cleaned the drive shaft and checked for any "run-out" or scoring. Ensuring the shaft is perfectly smooth and aligned is critical to the longevity of the new seal and bearings.
Lubrication & Housing Inspection: The bearing housings were purged of old, contaminated grease and replenished with high-temperature lubricant. We also inspected the pump impeller for signs of cavitation or debris damage to ensure peak hydraulic efficiency.
Vibration Testing & Re-Commissioning: Post-assembly, the pump was tested for operational smoothness. By reducing mechanical vibration through new bearings, we significantly lowered the decibel levels and structural stress on the connected piping.
Restored Efficiency: With new bearings, the pump operates at its intended RPM with lower amperage draw, providing immediate energy savings and reducing thermal stress on the motor windings.
Zero-Leak Integrity: The new mechanical seal provides a secure pressure boundary, eliminating water wastage and protecting the facility from the structural damage often caused by slow, unnoticed leaks.
Extended Asset Lifecycle: By addressing these core mechanical components before a catastrophic failure, we have extended the operational lifespan of the pump set by several years, avoiding the high cost of a complete unit replacement.
