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 • Fire service engineers / driver-operators • Company officers and instructors • Firefighter candidates studying pump hydraulics • Departments standardizing calculations and training aids Stop flipping through charts or spreadsheets. With Pocket Pumper, accurate PDP is just a few taps away—fast, precise, and ready for the fireground.
