In any chilled water HVAC system, chilled water pumps are the heart of the operation—responsible for circulating cooled water to maintain comfortable indoor climates. Over time, wear and tear on the pump and motor can reduce system efficiency, increase energy consumption, and risk unplanned downtime.
At Techtimia Engineering Singapore, we recently completed a critical chilled water pump overhauling and motor alignment project for a commercial facility—delivering enhanced performance, reliability, and long-term savings.
The Challenge: Degraded Pump Performance and Vibration Issues
Our client reported signs of declining system performance, including:
- Irregular water flow
- Excessive pump vibration
- Increased noise levels
- Higher energy usage
Upon inspection, our technicians confirmed that the pump components were heavily worn, and the pump-motor alignment was out of tolerance, causing stress on bearings and couplings.
Our Solution: Complete Pump Overhaul + Precision Alignment
Techtimia Engineering deployed a specialized HVAC maintenance team to execute a multi-phase restoration process:
Pump Overhauling Works
- Full disassembly of the chilled water pump
- Cleaning and inspection of all internal parts
- Replacement of worn components (e.g., bearings, mechanical seals, gaskets)
- Reassembly and system integrity checks
Motor & Pump Alignment
- Precision laser alignment between the pump and motor shafts
- Verification of alignment tolerances to manufacturer specifications
- Vibration analysis post-alignment to ensure operational stability
- Lubrication of bearings and torque checks on all bolts
This alignment work is critical—not just for energy efficiency—but also for preventing future mechanical failures, reducing noise, and extending the lifespan of both the pump and motor.
Why Proper Alignment and Overhauling Matters?
Misalignment and neglected pump maintenance can result in:
- Premature bearing failure
- Shaft and coupling damage
- Reduced hydraulic efficiency
- Higher operating costs
- Unplanned system shutdowns
Our proactive service ensured the client’s HVAC system was returned to optimal operating condition, with improved flow rate, quieter operation, and energy savings.
