Performance Data
A line graph illustrating performance data. The X-axis represents Flow in Gallons/Hour (and Liters/Hour), and the Y-axis represents Head in Feet (and Meters). Two lines are shown: one for 115V, 60 Hz, and another for 230V, 60 Hz, indicating the GPH/LPH output at various head levels. The graph shows that flow rate decreases as head increases for both voltage configurations.
