Centrifugal Pump Sizing Made Simple!

Selecting the right pump is not just about flow rate—it’s about understanding the complete system requirements.

In this infographic, you’ll learn:

Flow Rate Calculation

Flow Velocity Determination

Head Loss Estimation

Total Dynamic Head (TDH) Calculation

Pump Power Requirement Calculation

Efficiency Considerations

Remember:

A pump that is oversized wastes energy, while an undersized pump can affect production and process performance.

Before selecting any centrifugal pump, always calculate:

Required Flow Rate (Q)

Static Head

Friction Losses

Total Dynamic Head (TDH)

Motor Power

These are the fundamentals every Mechanical, Electrical, Instrumentation, and Process Engineer should understand.

Question for Engineers:

What is the most common mistake you have seen during pump selection or commissioning?
