While most pump definition information can be imported using the Pump Definition Table Type, tabular data including:

• Multipoint pump-head curves,
• Multipoint pump-efficiency curves,
• and Multipoint speed-efficiency curves

must be imported in their own table types.

To import these curves, first set up the pump definition type either manually in the Pump Definition dialog or by importing the pump definition through ModelBuilder. The Pump definition type would be Multiple Point, the efficiency type would be Multiple Efficiency Points or the Is variable speed drive? box would be checked.

In the field mapping step of the ModelBuilder wizard, the user the Table Type, Pump Definition - Pump Curve and would use the mappings shown below:

The example below shows an example of importing a Pump Head Curve. The process and format are analogous for flow-efficiency and speed-efficiency curves.

For the pump curves shown in the figure below, the data table needed is given. Several pump definitions can be included in the single table as long as they have different labels.

Upon running ModelBuilder to import the table above, three pump definitions would be created. The one called "Small" is shown below:
