Real mathWorked explanations
Learn by doing
A fire pump simulator built for repetition.
Memorizing a formula is not enough. FirePumpSim gives the formula a fireground context so students can practice choosing the inputs, calculating the answer and reviewing why it works.
Math you can review
See how nozzle pressure, friction loss, elevation and appliance loss combine into pump discharge pressure.
Daily challenge
Use short, repeatable questions to keep driver/operator calculations fresh between training evolutions.
Scenario library
Practice beginner through advanced problems across common hose layouts and fireground operations.
Printable training
Turn app practice into station drills, classroom worksheets and instructor-led review.
Train anywhere
Use the mobile app at the station, at home or before driver/operator testing—without creating an account.
60-second sample
What pump pressure would you set?
A 200-foot 1¾-inch attack line flows 185 GPM through a 50 PSI nozzle. There is no elevation or appliance loss.
PDP = NP + FL ± EP + AL
Inside the training
From attack lines to complex operations.
Use realistic layouts to connect the numbers to what the pump operator sees on the fireground.
Wye operations
Compare branch requirements and identify the controlling pressure.
Relay pumping
Review distance, flow, friction loss and engine placement decisions.
Rural water supply
Think beyond PDP with tender cycles, dump sites and sustained flow.
