A fire pump is any kind of pump that is part of a fire protection system’s water supply. … A fire pump can be powered by electric, diesel or steam and can supply fire sprinklers, standpipes, foam systems, water spray/mist systems or any combination of these systems.
Do I need a fire pump?
To determine if a fire pump is needed, the fire suppression system demands must be compared with the available water supply. If the supply cannot meet the demand, a fire pump is required. Conversely, if the water supply can meet the pressure and flow requirements, a fire pump is not needed.
Is code for fire fighting pumps?
|5120 : 1977||Technical requirements for rotodynamic special purpose pumps (first revision)|
|6070 : 1983||Code of practice for selection, operation and maintenance of trailer fire pumps, portable pumps, water tenders and motor fire engines (first revision)|
What should be posted near the fire pump?
Each discharge line for any other purpose must be clearly marked and must lead from a discharge manifold near the fire pump. (h) When a fire monitor is connected to the fire main system, it must lead from a discharge manifold near the fire pump.
What is jockey pump and fire pump?
Jockey PumpAsk Price. IntroductionA jockey pump is a small pump which is connected to a fire sprinkler system so that a certain pressure in the sprinkler system, and sized to ensure that if a fire-sprinkler is activated, there will be a system pressure drop.
Why is the centrifugal pump is the most common fire pump?
Centrifugal pumps are the most popular fire pumps and are classified as nonpositive-displacement pumps because they do not pump a definite amount of water with each revolution. Rather, this type of pump imparts velocity to the water and converts it to pressure within the pump itself.
What is the best fire fighting pump?

How much are fire pumps?
This can cost between $2,000-$3,000. It’s shocking to see the true cost of a fire pump replacement or repair.
How is fire pump pressure determined?
For example, if you have a 40,000-square-foot building that is all ordinary group 1, the calculation would be 1,500 x 0.15 (density) = 225 + 250 (hose demand) = 475 gpm total for the fire pump. If the structure has multiple hazards, the hazard with the highest gpm calculation dictates the pump size.
What is the maximum allowed suction head for the fire pump?
Because a perfect vacuum is never achieved and because some lift is lost to friction in the suction line, the maximum actual suction lift for a positive-displacement pump is approximately 22 ft. The maximum actual suction lift for a centrifugal pump is approximately 15 ft when pumping water from an open air tank.
