Fire Pump Calc

Version 2.0 — rebuilt UI, verified pump data from manufacturer specs, new visual design, and Fire Pump Calc is now available on Android.

Fire Pump Calc is the hydraulic reference tool built for the fireground — fast, accurate, and designed by fire service personnel for fire service personnel.

STRUCTURAL OPERATIONS Calculate pump discharge pressure for any structural attack scenario. Select nozzle pressure, hose diameter, hose length, flow rate, elevation, and number of appliances. Instant PDP output using industry-standard friction loss formulas. Metric/imperial toggle built in.

WILDLAND PUMP SPECS Full reference specs for five verified wildland pumps — Waterax MARK-3, Wick 80-4H, Honda WH20X, CET PFP-23hp, and CET PFP-11hp. Performance curves, engine specs, fuel type, weight, and max head pressure. All data verified against manufacturer documentation.

ADVANCED WILDLAND CALCULATOR Purpose-built for wildland initial attack. Select your pump, hose diameter, hose length, elevation, nozzle type, wyes and fittings, water source, and tank fill percentage. Outputs required PDP, GPM at PDP, max hose lay, max elevation, and estimated runtime — with a live indicator showing whether your required PDP is within pump capacity.

CUSTOM PUMP BUILDER Add your own pump specs and save them for future reference. Custom pumps appear in both Wildland screens and persist between sessions.
