View Full Version : How to create/insert pump curves

November 29, 2016, 01:20 PM
I'm trying to model water flow for a system of pipes and when I click on the Run Manager, I get this input error:

"Input Error 206: Pump U7000 refers to undefined curve".

My question is: How do I create a pump curve to select from. When I select my pump, the NPSH Curve dropdown is empty. The Infowater Help does not provide the help I need. I hope someone here can help me with my dilemma.

If you double click on the word "curve" for a pump curve or "NPSH Curve" in the model explorer when you have the pump selected as the active element, it will bring up the curve editor where you can create a curve. Once created and saved highlight it and hit the "OK" button and it will assign that curve to the pump.

You can also access the curve editor in the "Operation" tab of the model explorer under the "Curve" section. Just select curve and choose "NEW" and it will bring you through the create curve procedure.

Once a curve is created it will be selectable in the model explorer drop down under "Curve" or "NPSH Curve",
