Pocket Pumper

Pocket Pumper is the fast, field-ready hydraulics companion built for fire service engineers, driver/operators, and instructors. Get accurate pump calculations in seconds—so you can focus on tactics, water supply, and safety.
WHAT POCKET PUMPER DOES
• Calculates pump discharge pressure (PDP) for attack, supply, and master stream operations
• Combines friction loss, nozzle pressure, and elevation gain/loss in one clear result
• Uses industry-standard hose coefficients built in for common sizes and lengths
• Supports smooth bore and fog nozzles, plus common appliance losses
• Works for standpipe/sprinkler connections and large flows
WHY ENGINEERS CHOOSE IT
• Speed on scene: quick entries, big buttons, and instant results
• Precision you can trust: consistent math you can verify
• Built for the truck: high-contrast, glove-friendly UI
• Reliable offline: no signal needed once installed
CORE FEATURES
• PDP calculator: enter flow, hose, elevation, and appliances—see the breakdown (NP + FL + Elev + Apps)
• Nozzle support: smooth bore (by tip size/pressure) and fog (rated NP/GPM)
• Elevation assist: automatic add/subtract for gain or drop
• Appliances: account for gated wyes, master stream devices, FDCs, and more
• Quick picks: common hose sizes, lengths, and nozzle presets to reduce typing
• Units: US customary or metric
• Dark/Light modes optimized for day and night operations
BUILT FOR TRAINING & THE FIREGROUND
• Handy for academies, drills, and driver/operator prep
• Great as a fast check during preplans and inspections
• Confidence booster for new engineers and a solid refresher for veterans
SAFETY & TRANSPARENCY
• Shows how each result is formed so you can double-check on the fly
• Optional buffers and reminders to reinforce best practices (per your SOG/SOP)
• Highlights out-of-range inputs to reduce mistakes
DISCLAIMER
Pocket Pumper is a professional reference and training tool. Always follow your department’s SOG/SOP, manufacturer data, and the incident commander’s direction. Final pump settings are the responsibility of the operator on scene.
WHO IT’S FOR
