Fire Pump Capacity Calculator
A fire pump must deliver the design flow at the required head. Enter the flow, the total head, the pump efficiency and a motor sizing margin to get the shaft power, the sized motor power and the next standard motor rating. An indicative planning estimate — it runs entirely in your browser and stores nothing.
- Design flow2280 L/min
- Total head70 m
This is an indicative planning estimate, not a compliant fire design or a statutory calculation. The actual pump duty depends on the occupancy classification, the building height, the hydraulic losses of your specific pipework and the AHJ. A licensed fire consultant must design the pump set — against NBC (SP 7:2026) / NBC Part 4 and the relevant IS code (e.g. IS 3844 for hydrants) — and the local fire officer / AHJ signs it off. A wrong pump can mean no water when it matters: verify every figure. Nothing here is a Fire-NOC-ready number.

The fire pump set is the heart of a building's water-based fire protection - the main electric pump, the diesel-engine backup for India's power cuts, and the jockey pump that holds pressure so the mains do not cycle needlessly.

The fire pump is what gives sprinklers, hydrants and hose reels their pressure and flow. This professional upkeep guide covers the pump SET (main electric, diesel and jockey pumps and the controller), the weekly run test, auto-start checks, diesel engine and battery care, the DIY-safe vs contractor split, and the one rule that defeats everything if broken: leave the controller in AUTO.

How much firefighting water must a building store? Design flow times duration for the hydrant and sprinkler systems present, summed into a reserve in kilolitres. An indicative planning estimate; the dedicated reserve and real figures are set by a fire consultant to NBC.
Water DemandEmergency Exit Capacity Calculator
Does your building have enough exit width for its occupant load? Required width in 500 mm units versus what you provide, with the at-least-two-remote-exits check and a pass/fail. An indicative planning estimate; a fire consultant sizes exits to NBC and the AHJ approves.
Exit WidthEmergency Lighting Calculator
How many emergency luminaires light the escape route if the mains fails? Route length over the spacing plus open anti-panic coverage. A minimum count — you also need a fitting at each exit, stair and direction change. An indicative estimate; a consultant does the lux design.
