Performance Curves and Data (n= 1450 min⁻¹, 50 Hz)
Description of Performance Curve Graph: The graph displays the relationship between Head (H) in meters (left Y-axis) and Flow Rate (Q) in l/min and m³/h (bottom X-axis). Three curves represent the performance of models VXC4-40/100, VXC4-50/100, and VXC4-55/100. Equivalent flow rates in US g.p.m. and Imp g.p.m., and Head in feet are also indicated on secondary axes.
