Fire Pump Tools workflow

Use this category page as a workflow control surface: confirm entry conditions, run the tools, review quality gates, and keep the records.

PhaseWorkflow stepInputsOutputsQuality gate

Phase 1

Engineering

Start with sprinkler demand, hose allowance, elevation, and required pressure.Pump flow, Total head, System demandRated flow, Discharge pressure, HorsepowerInputs have been checked against drawings, device listings, field test records, or project criteria.

Phase 2

Engineering

Check pump flow, pressure, horsepower, and suction condition screens.Total head, System demand, ElevationDischarge pressure, Horsepower, NPSH availableOutputs including Rated flow, Discharge pressure, Horsepower, NPSH available have been reviewed before project use.

Phase 3

Engineering

Review outputs against project criteria, pump curves, and final hydraulic calculations.System demand, Elevation, EfficiencyHorsepower, NPSH available, Review flagsWarnings, failed screens, or narrow margins are documented before moving to the next workflow.

Entry conditions

  1. 1Use this workflow when the task belongs to fire pump tools and the controlling project condition is known.
  2. 2Collect Pump flow, Total head, System demand, Elevation before opening individual calculators.
  3. 3Confirm the values are project-specific, field-measured, manufacturer-listed, or selected from linked reference tables.

Records to keep

  1. 1Fire Pump Tools input source checklist.
  2. 2Reviewed output set: Rated flow, Discharge pressure, Horsepower, NPSH available.
  3. 3Linked reference values used for the calculation basis.
  4. 4Next-step review note for final calculation package, field review, or submittal check.
