Chilled Water Pump Head Calculation

Accurate sizing for optimal performance.
Correctly calculating the pump head is critical to selecting a pump that operates efficiently, meets system demands, and avoids costly energy waste or premature failure. EKG Malaysia provides professional pump head calculation and system analysis to ensure your chilled water pump is perfectly sized for your specific installation.

What is Pump Head?
Pump Head (in meters or feet) is the total pressure the pump must overcome to move water through the system. It is not just the height of the building.

Key Components of Total Dynamic Head (TDH):

1. Static Head (Hs) – Vertical height from the pump centerline to the highest point in the system.

2. Friction Head (Hf) – Pressure loss due to water flow through pipes, fittings, valves, and equipment (chillers, coils, etc.).

3. Pressure Drop Across Equipment – The manufacturer's stated pressure loss for the chiller evaporator, control valves, and balancing valves.

4. Velocity Head – Typically minor and often included in friction calculations.

The Risk of Incorrect Calculation

• Oversizing: Leads to excessive energy use, cavitation, and noisy operation.

• Undersizing: Results in insufficient flow, poor cooling, and system failure.

Our Professional Calculation Service
We use industry-standard methods (e.g., Darcy-Weisbach, Hazen-Williams) and software to model your system accurately, considering:

• Pipe material, diameter, length, and age

• All fittings, valves, and strainers

• Equipment pressure drops (chiller, cooling coils, AHUs)

• Design flow rate and safety factors

Why Choose EKG for Your Calculation?

• Accuracy: We avoid costly "rule-of-thumb" estimates.

• Local Experience: We account for Malaysia's specific design standards and common installation practices.

• Full Documentation: You receive a clear report with all assumptions, calculations, and pump selection recommendations.

• System Insight: Our analysis often identifies opportunities to reduce head loss through smarter piping design.

Don't guess. Calculate for confidence.
Proper pump head calculation is the foundation of an efficient, reliable chilled water system.
