System Curve for Two Pumps Operating in Parallel Explained

Understanding the system curve is essential when designing and operating HVAC pumping systems. In this video, we explain how the system curve changes when two pumps operate in parallel, and why the operating point moves instead of simply doubling the flow.

You’ll learn:

• What a system curve is
• How parallel pumps affect system performance
• Why the operating point shifts
• The relationship between pump curves and system curves
• Common misconceptions about pumps operating in parallel
• Real-world HVAC, chilled water, and condenser water applications

Whether you’re an HVAC engineer, contractor, technician, student, or facilities manager, this video provides a clear explanation of one of the most important concepts in pump system design.
