When fire protection serves an airport, the margin for error is exceptionally small.
John F. Kennedy International Airport is a complex transportation hub with aircraft operations, terminals, hangars, gates, support facilities, fuel related infrastructure, utilities, and extensive service areas. Protecting such a large environment requires more than individual fire pumps placed where needed. It requires a coordinated water supply strategy capable of supporting demanding fire protection requirements across a large network.
That challenge is exactly what made Callaghan Pump JFK Airport project significant.
Callaghan Pump supplied a 10 pump packaged fire protection system for JFK Airport. The system replaced an older arrangement that relied on diesel engines originally designed for commercial marine applications. The replacement solution included six diesel driven fire pumps and four electric driven fire pumps, creating a high capacity combination designed around the airport’s extensive fire pump loop.
According to Callaghan Pump, the JFK installation became the company’s largest packaged fire pump project and is described by the company as the world’s largest packaged fire pump system.
The project offers an important look at how high capacity fire protection systems can be approached when reliability, redundancy, hydraulic performance, equipment selection, and long term serviceability all matter.
Why JFK Airport Needed a Different Approach to Fire Protection
Large airports create a unique fire protection challenge because the protected area is not concentrated in one conventional building.
At JFK, the fire protection infrastructure includes a loop surrounding the airport that serves multiple hangars and gates. This means the pumping system has to support a distributed network rather than a single compact sprinkler installation.
A system of this scale introduces several engineering considerations.
Water must be delivered at the required pressure.
The pumps must provide sufficient flow.
The equipment needs to remain dependable under demanding operating conditions.
The system must accommodate multiple pumps and drivers.
The overall arrangement needs to support continuity of fire protection service.
And the equipment must be compatible with applicable fire protection requirements and the authority having jurisdiction.
This is where pump selection becomes much more than a product purchase.
A fire pump is one component within a larger fire protection system. Its capacity, driver, controller, suction arrangement, discharge piping, testing provisions, and interaction with the water supply all influence system performance.
NFPA 20, the Standard for the Installation of Stationary Pumps for Fire Protection, provides requirements covering fire pump installation, including pump equipment, pump rooms, piping, testing, and related system considerations.
For New York City projects, local requirements also interact with NFPA 20. NYC fire code provisions require fire pumps to be installed in accordance with the applicable construction codes and NFPA 20.
Replacing an Outdated Pumping Arrangement
One of the most interesting aspects of the JFK project was the equipment that existed before the upgrade.
Callaghan Pump reports that the airport’s previous fire pump engines were diesel engines originally intended for commercial marine applications. These engines operated at approximately 600 RPM, significantly below the rotational speeds commonly associated with many conventional fire pump arrangements.
So how could those engines drive fire protection pumps effectively?
The original arrangement used gear increasers to increase engine speed from approximately 600 RPM to the pump speed required for fire protection service. Callaghan Pump explains that the gear increasers converted the engine speed to approximately 1,750 RPM.
This arrangement demonstrates an important principle in industrial pump engineering: equipment can sometimes be made to perform outside what would now be considered the most straightforward configuration, but changing technology, equipment availability, maintenance requirements, and system expectations can eventually make replacement a better long term strategy.
For JFK, the Port Authority of New York and New Jersey sought recommendations for replacing the existing system.
Callaghan Pump recommended a completely new packaged configuration rather than simply continuing with the legacy approach.
The 10 Pump Configuration
The replacement system consisted of 10 horizontal split case fire pumps.
The configuration included:
Six Clarke diesel fire pump engines
Four Aurora electric driven fire pumps
Four 500 HP Aurora electric driven units operating at 4,160 volts
Packaged pump systems arranged for the airport’s high capacity fire protection requirements
Callaghan Pump's project information identifies the system as a combination of six diesel and four electric pumps.
This combination is particularly important when discussing resilience.
A large fire protection system should not be viewed only in terms of maximum theoretical output. Reliability also depends on how the system responds when individual components are unavailable, when maintenance is required, or when the facility experiences conditions that affect one source of power.
Using both diesel and electric driven pumps creates diversity in the driving equipment. It does not mean every pump operates simultaneously during normal conditions. Instead, the arrangement provides a substantial pool of fire pumping capacity designed around the system's overall demand and operating requirements.
That distinction matters.
The goal of a fire pump system is not simply to install the biggest possible equipment. It is to provide the required hydraulic performance within a properly engineered and code compliant system.
High Flow Capacity for a Large Airport Network
Callaghan Pump has also reported that each pump in the JFK packaged system was capable of approximately 3,500 gallons per minute at 150 PSI, giving the 10 pump system a combined nominal capacity of approximately 35,000 gallons per minute when considering all ten pumps together.
That number puts the scale of the installation into perspective.
A conventional commercial building may require a fire pump to support a comparatively localized sprinkler and standpipe demand. JFK's system had to support an airport wide fire protection loop serving multiple facilities.
The difference is enormous.
At this scale, hydraulic planning becomes critical. Engineers have to consider the available water supply, friction losses, elevation changes, piping configuration, required pressure, system demand, pump characteristics, and the operating relationship between multiple pumping units.
A pump's rated flow alone does not tell the complete story.
The pump must deliver the required flow at the pressure demanded by the fire protection system. Its performance must also be evaluated across the applicable operating range.
That is why pump curves, system calculations, equipment listings, control logic, and acceptance testing remain central to professional fire pump engineering.
Why Horizontal Split Case Pumps Made Sense
The JFK project used horizontal split case fire pumps.
This pump configuration is widely used in larger fire protection applications because it is well suited to high flow requirements and allows convenient access to major internal components during maintenance.
For a large installation, serviceability matters.
Fire protection equipment can remain installed for many years. That means the original equipment selection has implications far beyond the initial installation.
A pump room team may eventually need to inspect bearings, couplings, seals, impellers, shafts, or other components. A configuration that provides practical access can make future maintenance more manageable.
That is one reason lifecycle thinking should be part of fire pump selection.
The lowest initial equipment cost is not necessarily the lowest total cost of ownership.
For major facilities, decision makers should consider:
Capacity: Can the pump meet the hydraulic demand?
Reliability: Is the equipment suitable for critical fire protection service?
Redundancy: How does the overall system respond when equipment is unavailable?
Serviceability: Can technicians inspect and maintain the equipment efficiently?
Compliance: Does the equipment and installation satisfy applicable requirements?
Testing: Can the system be properly tested and documented?
Future support: Are replacement parts, technical expertise, and service resources available?
The JFK project illustrates why these questions become increasingly important as system scale increases.
Diesel and Electric Drivers Add System Resilience
Another defining characteristic of the JFK installation is its combination of diesel and electric drivers.
The project used six diesel driven pumps and four electric driven pumps.
For critical fire protection systems, driver selection is an important part of reliability planning.
Electric driven fire pumps can provide substantial pumping capacity where an appropriate electrical power source is available. Diesel driven pumps can provide an alternative source of mechanical power when electrical power availability becomes a concern.
NFPA 20 includes requirements addressing alternate power considerations for electric motor driven fire pumps.
However, the exact arrangement for any project must be determined from the project's engineering design, water supply, building conditions, electrical infrastructure, fire protection demand, applicable codes, and AHJ requirements.
The key takeaway is that driver diversity can be an important part of a broader resilience strategy.
For an airport operating around the clock, that resilience has particular significance.
Packaged Fire Pump Systems Simplify Complex Installations
Another notable aspect of the JFK project is that the pumps were supplied as packaged systems.
Packaging can provide advantages when a project involves multiple large fire pump assemblies.
Rather than treating every pump, driver, controller, and associated component as an isolated procurement item, a packaged approach can help coordinate equipment into an engineered assembly.
For large projects, this can improve consistency and simplify coordination between equipment suppliers, engineers, contractors, and facility representatives.
It can also help address space, installation, testing, and equipment interface considerations earlier in the project.
That does not eliminate the need for proper field installation.
Callaghan Pump identifies John P. Picone Inc. as the contractor responsible for installation of the JFK system.
This distinction is important because supplying the equipment and installing the complete fire protection system are separate responsibilities that must work together.
Successful fire protection projects depend on coordination throughout the process.
From Pump Selection to System Performance
One of the biggest lessons from the JFK project is that fire protection engineering should begin with the system requirement rather than a pump model.
Start with the question:
What does the fire protection system need to accomplish?
From there, engineers can determine the required flow and pressure, evaluate the available water supply, calculate system losses, establish pump requirements, select suitable equipment, and develop the appropriate control and testing arrangement.
This systems first approach becomes even more important for large facilities.
For example, increasing pump horsepower does not automatically solve a water supply problem.
Likewise, selecting a pump with a high flow rating does not guarantee that the required pressure will be available at the most hydraulically demanding point in the system.
The complete hydraulic picture matters.
This is also why fire pump sizing should not be based on assumptions or generic commercial building requirements. Every facility has different characteristics.
Testing Is Part of the Engineering Story
A fire pump system is only useful if it performs when required.
Testing therefore plays a critical role in fire protection.
Callaghan Pump states that its fire pumps undergo the required 50%, 100%, and 150% testing at the Aurora pump factory, with test results provided with each fire pump.
Field acceptance testing is another important part of the process. NFPA 20 includes provisions for field acceptance testing of pump units after installation.
For a major airport installation, testing becomes particularly important because the system is not merely an isolated piece of mechanical equipment. It is part of a critical safety infrastructure network.
Testing helps verify that the installed equipment performs in accordance with the intended design and provides an opportunity to identify installation or performance issues before the system is placed into service.
What Modern Fire Pump Engineering Can Learn From JFK
The JFK project remains relevant because today's fire protection challenges increasingly emphasize resilience, maintainability, and lifecycle performance.
Modern facility owners are also paying closer attention to equipment monitoring, preventive maintenance, documentation, energy considerations, and operational continuity.
That does not mean every older fire pump system needs to be replaced with the latest technology.
Instead, facility managers should evaluate whether existing equipment continues to satisfy current operational requirements and applicable regulations.
A system assessment can examine:
Pump performance
Driver condition
Controller condition
Water supply adequacy
Piping condition
Pressure performance
Test results
Maintenance history
Equipment availability
Code and AHJ requirements
Future facility expansion
This approach can reveal whether maintenance, rehabilitation, controls upgrades, equipment replacement, or a larger system redesign is appropriate.
The lesson from JFK is not simply that bigger pumps are better.
The real lesson is that critical infrastructure needs an engineered system designed around its actual risk and operating environment.
Why Airport Fire Protection Requires Specialized Pump Expertise
Airports are not ordinary commercial facilities.
They operate continuously.
They contain large open spaces, specialized structures, aircraft related facilities, passenger areas, mechanical systems, utility infrastructure, and extensive external networks.
Fire protection systems therefore need to be designed with the facility's complete operating environment in mind.
A pump supplier or engineer working on such projects must understand more than pump specifications. They need to understand hydraulics, drivers, controls, installation requirements, testing, applicable standards, and project coordination.
Callaghan Pump's portfolio includes other major New York area projects, including LaGuardia Airport, the Lincoln Tunnel, the World Trade Center, and major commercial and industrial facilities.
The company also reports that it supplied five packaged pump systems for LaGuardia Airport before receiving the JFK project.
That project history demonstrates how experience with one complex facility can contribute to understanding the challenges of another.
The Bigger Picture: Designing for the Moment That Matters Most
Fire pumps may sit idle for long periods.
That does not make them unimportant.
Quite the opposite.
Their value is measured by their ability to perform immediately when a fire protection system demands water.
For an airport, that expectation becomes even more critical.
The JFK installation demonstrates what happens when fire protection requirements are approached at infrastructure scale. Ten large packaged fire pump systems were brought together to serve a distributed airport fire protection loop. The configuration combined diesel and electric drivers and replaced a legacy arrangement that relied on specialized low speed marine engines and gear increasers.
It was not simply an equipment upgrade.
It was a strategic modernization of critical water pumping infrastructure.
Final Takeaway
Callaghan Pump's JFK Airport project demonstrates the engineering principles behind high capacity fire protection: understand the facility, evaluate the water demand, select equipment around the hydraulic requirement, build in appropriate resilience, and plan for long term service.
The project included 10 horizontal split case fire pumps, six diesel driven and four electric driven, with Callaghan Pump reporting approximately 3,500 GPM at 150 PSI per pump.
For a facility as complex as JFK Airport, that scale is not about achieving an impressive specification.
It is about creating dependable fire protection infrastructure capable of supporting a vast network when it is needed most.
And that is the real measure of a high capacity fire protection solution.
A successful fire pump system does not simply move water.
It delivers confidence that critical infrastructure has the pumping capacity, redundancy, and engineering behind it to respond when every second matters.
