Pump Curve Combinations

There are a number of ways to view pump curves including Components > Operational > Pump Definition which shows all available pump curves, and right clicking on a pump and selecting Pump Curves once a run is complete. Users also may want to view the performance of multiple pumps running together in parallel in a pump station. The display of multiple pump and system head curves is accomplished using the Bentley pressure solver which is only available when the active solver is set to GVF-convex.

To view combination pump curves it is first necessary to include the pumps in a Pump Station element. This can be done by opening the property grid for the pump, picking the Pump Station property and selecting the pump station in which this pump is located. It is usually advisable to draw the pump station polygon to include the pumps within the polygon (See ”Pump Stations’).

The pump head and efficiency characteristic curves are properties solely of the pump and can be displayed even if the model only consists of the pump station with the pumps. If the user wants to display system head curves, then the pump station must be part of a valid hydraulic model.
