Pump Chart Generator Guide – Build Standard Packages (Fast Charts Crews Actually Use)
Last updated:
Pump charts exist to remove complex math from high-stress moments. Use the Pump Chart Generator after you understand your package PDP logic (see PDP and Friction Loss).

Step 1: Choose Standard Packages
- Pick your most common attack line package (line + nozzle + flow goal).
- Add one long lay / setback package (often larger diameter to a gated wye).
- Add one high-flow/defensive package if your district needs it.
Step 2: Build PDP Logic Once
- Confirm friction loss: Friction Loss
- Compute PDP for lengths you actually stretch: PDP
- Then generate a chart that matches those packages.
Step 3: Train the Chart
- Teach the package names (so crews speak the same language).
- Run 5-minute drills: “stretch + length estimate + chart pump.”
- Review mistakes: wrong package, wrong length, over-correction.
Common Mistakes
- Too many chart rows = nobody uses it.
- Packages don’t match real nozzles/flows.
- No training = chart becomes decorative.
