Before starting the diesel fire pump, it is important to remember some basic tips and precautions.
First, make sure the vehicle has the right fuel level. The tank should never be less than two thirds full. This is to ensure the engine can operate for the required amount of time. Second, if it is left unused for a long period of time, the fuel will start to degrade. In order to avoid this problem, the fuel tank should be emptied on a regular basis.
Lastly, a diesel fire pump should undergo weekly inspections and tests. Regular tests are required for its durability, reliability, and performance. Weekly no-flow testing is required by NFPA 25 and is different for each type of pump. In order for a diesel fire pump to work properly, the engine must be operated for 30 minutes with no water flowing through it. A manual isolation valve must be installed on the supply and discharge ports. These valves can be used for testing purposes.
The size and installation of a diesel fire pump depends on the building's space, existing infrastructure, and operating requirements. The most common options are diesel engines and electric motors. High horsepower diesel pumps require 460-volt, three-phase power. Steam turbines are also an option, although they are uncommon. The space required for a diesel pump will depend on the engine's horsepower. If space is a concern, a steam turbine may be the best choice.
A backup source for the fire pump is usually an on-site generator. This backup power is required to meet NFPA 20 requirements for running a pump at locked rotor current. This is six times its full load current. A generator is too small to drive a large diesel fire pump that has more than 150 horsepower. The backup power source must provide an automatic transfer switch. In addition, a backup source should be available for at least 8 hours during a power outage.
For a diesel fire pump to operate properly, it must be equipped with a dedicated fuel tank. The tank must be above ground and installed per jurisdictional requirements. It should also have a fill valve, vents, and a visual fuel level gauge. When considering the size of a diesel fire pump, you should also consider how many gallons of fuel it will need to run the pump. The fuel tank should be a part of the fire pump room and maintain a steady temperature.
NFPA 20 requires the installation of a diesel engine fire pump. The room must be properly sprinklered. It should also be protected from flood waters, explosions, and other effects. Depending on your needs, you may decide to install a diesel fire pump. But make sure that you check all the requirements and installation procedures carefully. If you are unsure, it is best to consult with a fire safety professional. This will ensure that the pump is installed properly and safely.
