AHU Condensate Lift Pump Repair | High-Head Drainage & Flood Prevention by EKG (Malaysia) Sdn Bhd

Why AHU Condensate Lift Pump Failure Needs Immediate Attention?

AHUs produce massive condensate volumes. When the lift pump fails, water overflows drain pans, soaks insulation, and cascades through ceilings—collapsing tiles, damaging finishes, and breeding microbial contamination. Unlike small FCU pumps, AHU lift pumps handle higher flow, greater lift heights (10–30+ metres), and continuous duty. Failure is not a minor inconvenience—it is a building emergency. EKG (Malaysia) Sdn Bhd delivers specialized AHU condensate lift pump repair, restoring drainage and preventing catastrophic water damage.

Our AHU condensate pump repair services cover:

• Central AHU Drain Pans & Lift Stations

• Large-Capacity Condensate Pump Sets

• High-Head Condensate Lift Applications (10–30m+)

• Multi-AHU Collection Manifolds

• Critical Facility Air Handling Systems

• Ducted Return & Plenum-Mounted Units

Common AHU Condensate Pump Failure Modes

• Float Switch Failure – Stuck, corroded, or incorrectly adjusted

• Motor Burnout – Continuous duty, voltage fluctuation, age-related degradation

• Impeller Blockage – Slime, insulation fibres, construction debris

• Check Valve Leakage – Backflow causing short-cycling and tank overflow

• Discharge Line Blockage – Kinked hose, algae, insufficient slope

• Tank Sensor Malfunction – Electronic probe coated or failed

• Alarm Circuit Fault – No notification during failure

• Corroded Terminals – Moisture ingress into control board
