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. WebFirst, the red line on the left hand side of the pump curve is the Minimum Continuous Stable Flow (MCSF) line. This is the point beyond which the pump manufacturer has determined the pump should not be allowed to …
WebMCSF is a value that can range from roughly 10% to 80% of Best Efficiency Point flow depending on pump size and type, operating speed, impeller suction geometry, liquid density, and other factors. A size 2” (50mm) discharge single-stage process pump may have an MCSF as low as 10% of BEP flow. 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
