Free Fire Service Calculators for Your Website

Every PumpForge calculator can run on your own website. Copy one line of HTML and it works — free for fire departments, academies, training divisions and instructors. No account, no fee, no catch.

Free, permanentlyNo licence, no sign-up, and no expiry. Use it on as many pages as you like.

Nothing to installOne iframe tag. It works on WordPress, Squarespace, Wix, SharePoint or plain HTML.

No tracking of your visitorsThe embed sets no cookies and runs no analytics. It calculates and nothing else.

Same engine as the simulatorIdentical hydraulics to the PumpForge training simulator, so the numbers match what your crews train against.

The snippet includes a small credit line linking back to PumpForge. Please keep it — that link is the whole reason we can give these away. Beyond that, use them however is useful: a hydraulics page for your recruits, a study aid on a course page, a quick reference on a station intranet.

The eight calculators

Each one is live below. Copy its snippet, paste it into your page, and you get exactly what you see here.

Pump Discharge Pressure (PDP)

Nozzle pressure plus friction loss, elevation and appliance loss — the core pump-operator calculation.

Want something we haven’t built?

If there is a calculation your department teaches that is not here, tell us and we will look at building it. Get in touch.

Prefer a printable version? The fireground hydraulics cheat sheet puts every formula on one page, and the guides library has the reference charts. All tools use standard IFSTA / NFA / NFPA 1002 formulas for training and estimation — always verify against your department SOPs and manufacturer ratings.

The calculators are free. The training is where it sticks.

PumpForge puts your operators on a realistic pump panel running these exact hydraulics — 15 built-in scenarios, automatic scoring, after-action reports, certifications. Every station, any computer or tablet.
