TL;DR
A pool pump curve is the manufacturer's graph plotting how much water a pump moves against each level of system resistance, with flow in gallons per minute on one axis and total dynamic head in feet on the other. Designers find the operating point where this curve crosses the plumbing's system curve, confirming the pump can achieve turnover and still feed the heater, cleaner, and water features.
What it means
A pool pump curve is the manufacturer's graph plotting how much water a pump moves against each level of system resistance, with flow in gallons per minute on one axis and total dynamic head in feet on the other. Designers find the operating point where this curve crosses the plumbing's system curve, confirming the pump can achieve turnover and still feed the heater, cleaner, and water features. Variable-speed models publish a family of curves, one per motor speed.
