Multiple Configurations

A single pump junction can contain information for multiple pump configurations - impeller trims and operating speeds. This is useful to compare different variations of a pump without needing to redefine a new pump junction for every case. The configuration of the pump can easily be changed without losing any information.

Multiple configurations also allow for an analysis of pump reliability factors.

Defining Multiple Configurations

When opening the pump configuration, change the Configuration Method from Simple to Multiple. When doing so, an additional user input panel appears on the right hand side of the window.

Pump Configuration window Multiple selected for the Configuration Method.

In order to make use of the multiple configuration feature, an RPM and Impeller Diameter under Configuration Information should be filled in. A Description can optionally be added. After modifying any information that affects the definition of this configuration the Update Configuration box turns yellow:

The pump curves must be created and curve fit, as with a single configuration pump. After completing this and clicking Update Configuration Now, the new configuration will be created and shown in the Pump Configurations area. Configurations can be edited by selecting them in this area.
