WebThe pump manufacturers are interested in providing pump performance curve in a way that does not depend on to the pumped fluid physical properties. That is why they are using head instead of pressure. The following formula converts pressure to the head; H(meter) = 10.2 P/SG or H(feet)= 2.3P/SG Web16 mei 2013 · The pump flow capacity, shown on the x-axis of the pump performance curve, represents the gallons per minute (gpm) that the pump will pump at any given point during its operation. The corresponding values of the flow capacity and head are plotted on the main curve on the graph at various impeller sizes.
