What Is Pump Sizing Software?

Pump Sizing Software calculates required pump head and operating flow from system conditions so engineers can select a pump that can meet duty requirements. It can be used for quick duty-point matching, like Grundfos Pump Selector and Wilo Select, or for full network simulation, like AFT Fathom and Pipe Flow Expert. Many tools connect piping pressure losses to pump operating points using system curves and pump curves so the selected configuration satisfies constraints like elevation changes, fittings, and boundary conditions. This software is used by mechanical, process, and plant engineering teams to reduce manual curve matching and to verify operating behavior beyond a single estimate.

Key Features to Look For

The best Pump Sizing Software tools translate system losses into pump operating-point checks with the modeling depth that matches the project scope.

  • Choose the modeling depth that fits the project scope

    Select Pipe Flow Expert when the project depends on friction-heavy piping and realistic system curves built from detailed pipe, fitting, and valve modeling. Select AFT Fathom or AFT Arrow when the task requires network-wide energy-balance hydraulics with pump performance curve integration across complex fittings and boundary conditions.

  • Decide whether the goal is network validation or pump candidate shortlisting

    Use AFT Fathom or AFT Arrow to simulate pressure loss across full piping networks and validate head, flow, and pressure outputs as design checks. Use Grundfos Pump Selector, Wilo Select, or Armstrong Pump Sizing Tools when the goal is to map defined duty requirements to a manufacturer-specific pump lineup with curve-based operating-point verification.

  • Plan for input effort and iteration speed on large models

    If modeling large networks with many components, expect setup time in AFT Fathom and demand disciplined setup in AFT Arrow because setup can be demanding for complex branches.
