SWMM - Curves - Pump Curves

Describes the flow variation as a function of load/depth in SWMM Pumps

It is assigned to a SWMM pump when the Constructor (gravity linear) of device associates this to tool Pump

Can also be assigned to pump for a control rule

A pump curve has the following properties:

• Identification
  • Description (Description, String) - Use a user-friendly description when the item name is not sufficient
  • Name (Name, String) - item name
    Avoid names that are too long or contain the following characters: '*', '>', '<', '/', '\', '"', ':', ';', '|', '=', '`', '#', ',', '?'
• Object
  • Priority (Priority, Enum) - Information regarding the item's current status. Can be:
    • Neutral: no issues
    • Critical: A problem preventing the calculation or use of the item
  • Error Assessment (CurveError, Enum) - Result of the data assessment
  • Curve Data (CurveData, IListClonavel) - the curve data, with the columns:
    • Volume or Depth (X, Double) - volume or depth controlling the pump
    • Flow Rate (Y, Double) - the value to be used
• SWMM
  • Pump Type (PumpType, Enum) - Defines pump curve data types:
    1. Incremental Volume/Flow - An off-line wet sump pump where flow increases incrementally with available wet sump volume
    2. Depth/Incremental Flow - An in-line pump where the flow increases incrementally with the depth of the inlet node
    3. Continuous Load/Flow - An in-line pump where the flow varies continuously with the difference in load between the inlet and outlet nodes
    4. Depth/Continuous Flow - A variable speed in-line pump where the flow varies continuously with the depth of the inlet node
    5. Variable Speed - A variable speed version of the Type 3 pump where the head v. flow curve shifts position depending on the pump's speed setting

The data is populated in the table and plotted on the graph for better visualization:

Volume/Depth/Load values must be in ascending order and not repeating and cannot be negative, otherwise the Priority property will be as Critical
