Prepare the inputs
Gather the flow, head, fluid, power, material, and installation constraints before opening a provider tool.
External tools
External Tools and Calculators
A curated directory of official vendor, manufacturer, and catalog tools for engineering workflows that require product-specific data.
External tool guides
Each guide explains when to use official external tools, what inputs to gather, and which calculations can check the setup.
How these directories are used
Check the engineering assumptions first, then use official provider tools where product curves and configuration data matter.
Check the assumptions
Use related calculators and references to catch obvious pressure, head, and velocity issues before product selection.
Open official tools
Follow the checked link to current provider data and review the tool disclosure before leaving the site.
Tool suggestions are curated links, not independent validation of provider outputs. See the source and review policy for how external tools are handled.
