CAE Software for Preliminary Design

PUMPAL®

CAE Software for Axial and Radial Pumps

A meanline approach is used to design centrifugal pumps and mixed-flow pumps with single and multiple stages. PUMPAL is used to design the stage, analyze performance, refine the parameters with data reduction, and model the machine according to several performance models. PUMPAL's unique Design Wizard leads the user through all the necessary steps for design, analysis, and data reduction. The meanline pump design can easily be sent to the AxCent®program for further blade design and fluid dynamic analysis.

Components Supported by PUMPAL:

  • Inlet guide vanes
  • Open or closed impellers
  • 2D or 3D impellers
  • Front and rear seals (multiple)
  • Diffuser types, including…
    • Arbitrary vaned
    • Vaneless
    • Wedge/channel
    • Cascade
    • Conical
    • 90/180 degree bends
  • Exit elements, including…
    • Collector
    • Volute
    • Return channel
  • Various leakage paths
  • Multistage pumps

Modeling

PUMPAL supports two-elements-in-series (TEIS) rotor diffusion modeling, two-zone loss modeling, radial and axial stator diffusion/losses, volutes, inlet cavitation, disk friction, exit mixing, cavity leakage, and more. PUMPAL uses the same consistent model of the stage performance for design, analysis, and data reduction modes.

Integrated Performance Map Plotting

Review design performance, analysis, and test data with flexibly plotted performance maps, updated automatically with each geometric change.

Easy Editing

View the pump stage in an active, true-scale meridional view. Edit the parameters by double clicking on the component in the meridional view. Parameters can also be edited using a single text input/output file, a feature especially useful for optimization.

Tabular View of Results

View the results in a flexible, spreadsheet-like table format, customizable through separate filters. Create any number of filters, select what to display, and customize the labels as well.

Axial View with Inlet and Exit Velocity Triangles

Using the window view, view blades and velocity triangles at the impeller inlet and exit. View inlet velocity triangles for the hub, tip, or RMS radius, and exit velocity triangles for the primary and secondary zones, and mixed-out state.

A Real Fluid Program

PUMPAL calculates Real Fluid properties using a variety of equations of state options.

Direct Integration with AxCent®

Start AxCent automatically from PUMPAL, with the initial meanline geometry transferred automatically to AxCent. Changes in AxCent that affect the meanline analysis will cause the meanline analysis to be rerun and all performance maps to be regenerated.
