In a hydronic cooling system, water is the medium that carries thermal energy away from your building. The pump is the "heart" of this circulation process. If the pump loses efficiency or fails, the hydronic balance is destroyed, leading to "hot spots" in certain zones, increased chiller load, and potential pipe damage due to water hammer or cavitation. EKG (Malaysia) Sdn Bhd specializes in Hydronic Cooling System Pump Repair, ensuring your chilled water or condenser loops maintain the exact flow and pressure required for peak thermal performance.

Inconsistent Differential Pressure (Delta-P) – Difficulty maintaining constant pressure across the supply and return headers.
Mechanical Seal Seepage – Loss of treated water and system pressure, often caused by thermal cycling or improper alignment.
Hydraulic Noise & Cavitation – Popping or gravel-like sounds indicating the pump is operating outside its design curve.
Air Ingress – Failed seals or gaskets allowing air into the loop, causing "gurgling" and corrosion throughout the piping.
Motor Overload (Tripping) – Increased mechanical resistance within the pump casing forcing the motor to draw excessive current.
We replace worn seals with high-performance materials (Silicon Carbide/Tungsten) designed to handle the specific chemical treatments and temperature ranges of hydronic cooling loops.
We extract worn bearings and inspect the shaft for "run-out" or scoring. Using precision extraction tools, we install high-load bearings that ensure silent and stable rotation under continuous duty.
We inspect the impeller for erosion and mineral scaling. We offer dynamic balancing and internal ceramic coating to restore smooth water flow and reduce energy-sapping turbulence inside the pump casing.
Hydronic pumps are sensitive to misalignment. We use advanced laser alignment tools to synchronize the motor and pump shafts, eliminating the vibration that leads to premature seal and pipe joint failure.
We service the "Triple Duty Valves" and suction diffusers associated with the pump. Ensuring these components are clean and functional is vital for maintaining the correct hydronic balance and protecting the pump from debris.
For systems utilizing Variable Frequency Drives, we verify that pressure transducers and sensors are providing accurate data to the controller, ensuring the pump modulates its speed efficiently based on real-time load.
Hydraulic Engineering Experts – We understand the complex thermodynamics of hydronic balancing, not just the mechanical pump body.
ISO-Certified Quality – Our repair protocols ensure that your system remains compliant with international building and safety codes.
Klang Valley & Selangor Coverage – Rapid response to stabilize critical cooling systems in commercial towers and industrial plants.
Performance-Driven Results – We focus on restoring the pump's "Best Efficiency Point" (BEP) to help you lower building operational costs.
