In modern commercial buildings, mechanical room space is often at a premium. Vertical In-line Circulation Pumps are specifically designed to address this challenge. By mounting the motor vertically above the pump casing and aligning the suction and discharge ports in a straight line, these pumps can be installed directly into the piping header. This eliminates the need for large concrete inertia bases and complex 90-degree "elbow" piping, making them the ideal choice for feeding Air Handling Units (AHUs).
EKG (Malaysia) Sdn Bhd provides expert sizing, installation, and maintenance for vertical in-line pumps, ensuring your AHUs receive the precise flow required for optimal climate control.
Compact Footprint: Unlike horizontal end-suction pumps, vertical in-line units require minimal floor space. Smaller models can even be "pipe-supported," freeing up valuable room in crowded mechanical closets.
Simplified Piping Design: The "straight-through" flow path allows for a much cleaner MEP (Mechanical, Electrical, and Plumbing) layout, reducing the number of fittings and potential leak points.
Ease of Maintenance: Most vertical in-line pumps feature a "Top Pull-Out" design. This allows EKG technicians to service the impeller, mechanical seal, and motor without disturbing the main piping connections.
Reduced Vibration & Noise: Because the water enters and exits in a straight line, there is less internal turbulence compared to pumps that force water to make a 90-degree turn. This is critical when AHU rooms are located near occupied offices or hotel rooms.
AHUs require a specific "Total Dynamic Head" (TDH) to overcome the friction of the cooling coils and control valves. We perform detailed hydraulic calculations to ensure your pump provides the exact flow needed. An undersized pump will lead to poor cooling, while an oversized pump causes "hunting" valves and energy waste.
The vertical orientation of these pumps puts a unique load on the upper motor bearings and the mechanical seal. We provide ISO-certified overhauls using high-temperature-rated Silicon Carbide seals to prevent leaks and ensure silent operation.
We specialize in pairing AHU pumps with Variable Frequency Drives (VFDs). As the AHU's 2-way control valve closes, the VFD slows the pump down, protecting your pipes from over-pressurization and reducing your building's monthly electricity bill by up to 50%.
While inline pumps are compact, they must be perfectly vertical to avoid shaft stress. We use specialized leveling tools and vibration isolation hangers to ensure the mechanical "hum" of the pump does not travel through the building’s structure.
As an MEP specialist based in Selangor, we understand the technical synergy between the pump and the AHU. We don't just service the hardware; we optimize the entire water loop for maximum cooling efficiency. Our team provides rapid on-site diagnostics and repair services across the Klang Valley to keep your building's air conditioning reliable and cost-effective.
