A pump can be added to any pipe, except a pipe that contains a control valve. 


Options are provided to choose how the pump should be modeled:


  • A Fixed Flow Rate Pump


  • A Fixed Head / Pressure Rise Pump


  • A Fixed Speed Pump (with a flow versus head performance curve)


A pump’s properties, including its pump curve, are defined and graphed on the Pump Data screen. The Pump Data screen has an interactive graph that allows you to determine which elements of the pump graph are displayed. It also provides functionality to calculate pump values for different points on the graph, including the pump’s flow rate, head added, operating efficiency percentage and NPSHr (Net Positive Suction Head requirement).


You can also save the data associated with a Pump to the Pump Database or a .pfpm file. This provides a way to share the pump data, and quickly load the pump data, when the same type of pump is used again in the pipe system or a future pipe system. Saving and loading pump data also provides a quick and easy way to evaluate different pumps at a specific point in the pipe system to determine how each one affects the system.


NOTE: Be sure to enter the values for the pump data in the correct units (you can select which units you wish to use). For example, if you are using metric units, and m for meter is displayed next to a field, enter the pump value in meters.
