Fire pumps sit, usually silent and nondescript, in the basements or bottom stories of skyscrapers. If there were a fire on the top floor, these pumps would send water through the pipes with enough force and volume to keep firefighters safe and extinguish the flames. They work by increasing the existing water pressure to reach the desired level for sprinkler systems to operate.

The type of pump required can be determined by calculating the amount of water flow needed in gallons per minute and the maximum head (water pressure) desired in feet of water. These calculations can then be compared to the available information found on fire fighting pump data sheets. The fire fighting pump can be diesel or petrol driven, have an electric or recoil start, and have an inlet valve to draw from the water source and a discharge valve for moving water out of the system.

Some notable fire pumps for sale include the Mark-3 High-Pressure Portable Fire Pump, which uses a Nikasil-coated cylinder and impregnated crankcase to withstand rigourous operations such as those performed by forestry agencies in the fight against wildfires. Another great choice is the steel tank fire pump, which can be taken on the road by utilities, loggers and railroads — anyone working in remote areas where a fire could break out.
