AFT Fathom 8 can be used to quickly and easily model multiple pump configurations with different pump speeds and impeller sizes.  First, determine a particular pump curve to use from either a manufacturer’s pump curve or pump curve verification test data.  Next, determine new pump curves for head and flow using the affinity laws considering either a change in pump speed or impeller size.  The multiple pump curve data sets will then be entered for each particular pump configuration. In Figure 1 (click on the image to see it larger), there are a few pump configurations that have already been defined. ...
