⚠️ Engineering Note

This calculator supports preliminary pump-system evaluation. Final pump and motor selection must be confirmed using the approved project design basis, verified piping data, operating cases and certified manufacturer performance curves. NPSH margin requirements must follow the applicable project and company standards.
