Performance Data

TOTAL DYNAMIC HEAD FLOW PER MINUTE

Graph Description: HEAD CAPACITY CURVE MODEL 840/841

The performance curve displays the relationship between Total Dynamic Head (measured in feet on the left Y-axis and meters on the right Y-axis) and Flow Rate (measured in Gallons per Minute on the bottom X-axis and Liters on the top X-axis). Two distinct curves represent the performance of Model 840 and Model 841 pumps across various flow rates.
