In luxury residences, private hospitals, and corporate offices across Selangor, the sound of mechanical equipment can be as disruptive as a lack of water pressure. Traditional booster pumps often generate "airborne noise" (mechanical hum) and "structure-borne noise" (vibrations traveling through walls). A Quiet Booster Pump is engineered to remain imperceptible to occupants while delivering high-performance flow.
EKG (Malaysia) Sdn Bhd specializes in "Silent Pumping" solutions, utilizing advanced acoustic engineering to ensure your water pressure is felt, but never heard.
| Noise Source | Root Cause | Technical Fix by EKG |
| Mechanical Hum | High-speed (2-pole) motor rotation | Specifying Low-RPM (4-pole) motors or encapsulated designs. |
| Vibration | Rigid mounting to the floor/walls | Installation of Spring Isolators or Inertia Bases. |
| Hydraulic Rushing | Turbulence or Cavitation | Selecting pumps that operate at their Best Efficiency Point (BEP). |
| Pipe Rattling | Water Hammer or poor support | Installing Flexible Connectors and independent pipe anchors. |
Standard pumps use a loud external fan to cool the motor. Premium quiet models (like the Grundfos SCALA2) use the pumped water itself for cooling. This eliminates the fan noise entirely, often achieving sound levels as low as 47–54 dB(A)—similar to the hum of a quiet refrigerator.
Standard pumps start and stop with a loud "click" and a sudden pressure surge. Our Variable Frequency Drive (VFD) systems ramp the speed up and down gradually ("Soft-Start"). By running at lower speeds during periods of low demand, the pump stays nearly silent for 90% of its operating life.
Vibration is the primary enemy of silence. We utilize pumps with Dynamically Balanced Impellers and perform Laser Shaft Alignment on-site. This ensures the motor and pump are perfectly synchronized, eliminating the mechanical "whine" caused by misalignment.
To guarantee a noise-free environment, EKG technicians follow a strict acoustic protocol:
Acoustic Isolation: We use high-density rubber pads to decouple the pump from the building structure.
Flexible Hose Integration: Braided stainless steel hoses are used to prevent the pump's vibration from turning your building's copper or PPR pipes into a giant "speaker."
Encapsulation: For sensitive areas like recording studios or hospitals, we provide custom-fitted Acoustic Enclosures with internal sound-absorbing foam.
PID Tuning: We calibrate the VFD controllers to avoid "hunting," a common cause of erratic motor noise.
As an MEP specialist in Selangor, we don't just understand plumbing; we understand the physics of sound. We source ISO-certified, ultra-quiet brands like Grundfos, Tsunami, and Puregen, ensuring your facility meets international wellness and acoustic standards. Whether you are retrofitting a high-rise in KL or installing a system for a luxury home, we provide a silent, powerful, and professional result.
