Pump Chart Generator Guide – Build Standard Packages (Fast Charts Crews Actually Use)

Last updated:February 14, 2026

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

1. Teach the package names (so crews speak the same language).
2. Run 5-minute drills: “stretch + length estimate + chart pump.”
3. 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.
