Air Conditioner Lift Pump

Reliable vertical lift for challenging AC condensate drainage.
An air conditioner lift pump is a condensate pump specifically engineered to move water upward when the indoor unit is installed below the nearest drain point. EKG Malaysia supplies and installs robust lift pumps capable of vertical lifts of 5 to 30+ meters, solving drainage problems in basements, multi-level voids, and complex commercial buildings.

How It Works:
Condensate collects in a reservoir. A float switch activates a powerful, pressure-rated pump that pushes water through a dedicated discharge line to a drain located at a higher level.

Key Features for Vertical Lift:

• High-Head Motors: More powerful than standard condensate pumps, designed for continuous pressure.

• Durable Construction: Reinforced components (diaphragms, valves) to handle repeated high-pressure cycles.

• Large Capacity Tanks: Reduce pump cycling frequency, extending motor life.

• Dual Float System: One float for pump activation, a separate high-level float for alarm/backup.

• Discharge Line Check Valve: Prevents backflow and maintains prime.

Critical Applications:

• Basement & Sub-Basement AC Units: Where the drain point is on a higher floor.

• High-Rise Vertical Riser Drainage: Collecting condensate from multiple floors and pumping to roof level.

• Underground Car Park Plant Rooms: Lifting water to street or ground level drains.

• Retrofits in Buildings where original drainage design is inadequate.

Design & Installation Considerations:

1. Accurate Head Calculation: Vertical lift + horizontal run + friction losses = Total Dynamic Head (TDH).

2. Pipe Specification: Must use pressure-rated tubing (often reinforced) and secure fittings.

3. Venting: May require an air admittance valve to prevent air locks in the discharge line.

4. Alarm Integration: Essential to alert staff of a primary pump failure before overflow occurs.

Our Lift Pump Service:

• Site Survey & Head Calculation: We measure the exact lift and run to specify the correct pump.

• Complete System Supply: Pump, tank, valves, alarm, and correct piping.

• Professional Installation: Ensuring a reliable, code-compliant, and serviceable system.

• Testing Under Load: Verifying performance at the calculated TDH.

Don't let gravity limit your AC installation.
A professional lift pump system provides a permanent, reliable solution for negative drainage scenarios.
