Why Engine Options Matter in Fire Protection Systems
Every fire pump system is unique. Different environments, local codes, pump layouts and risk profiles demand a range of engine configurations.
Clarke engine options give system designers and installers the capabilities to ensure:
- Compliance with NFPA 20 and UL/FM standards and jurisdictional requirements
- Reliability through redundancy and protective features
- Installation efficiency and reduce field modifications
- Longevity with components built for harsh conditions
You can trust that any optional accessories are tested, certified and engineered for maximum utility.
Clarke Engine Accessory Categories
Explore the most commonly used Clarke fire pump engine options grouped by function and application. Each accessory is designed to meet the demands of real-world fire pump environments.
Power & Starting Options
Battery Kits
Ensure reliable engine startup when seconds matter. Clarke battery kits are engineered to meet NFPA 20 requirements and deliver peak cranking amps, even in extreme temperatures. They are essential for indoor and outdoor systems where local power quality varies. Clarke currently offers Absorbed Glass Matt (AGM) Battery Kits.
Secondary Starting Methods
Clarke offers dual electric start systems and combinations such as electric plus pneumatic or hydraulic starting. Secondary starting methods are mandated for many installations to ensure start-up redundancy during fire events.
Cooling & Air Handling
Cooling Loops
Clarke cooling loop kits maintain engine operating temperature by circulating coolant through a heat exchanger connected to the fire pump discharge. Perfect for installations without radiators or for installations with a dedicated water source.
Air Filters & Cleaners
Factory-installed heavy-duty air filters protect engine from dust and contaminants. Used in high-particulate environments like industrial facilities, pump rooms near loading docks, or installations with wind blown sand or salt spray.
Fuel & Exhaust System
Fuel Connection Hoses
Flexible, code-compliant fuel hoses simplify installation and reduce leak points.
Exhaust Systems
Silencers and custom exhaust system kits reduce noise and heat discharge, protecting building occupants and nearby equipment. Used in indoor pump rooms or systems near occupied spaces.
Control & Monitoring
Engine Instrument Panel
Includes RPM, oil pressure, coolant temperature and diagnostic indicators for at-a-glance engine health monitoring. Required for all installations per NFPA 20.
Alarm Panels & Gauges
Supplement your panel with audible/visual alarms and mechanical gauges for backup verification. Alarms and gauges are mission-critical systems requiring multi-point status checks.
Mechanical Interfaces
Driveshafts
Precision-balanced driveshafts ensure efficient power transfer from engine to pump while minimizing wear. Custom-fit for various pump layouts.
Torsional Couplings
Engineered to dampen vibrations, protect bearings and extend the life of critical rotating components.
Vertical Bases
Save space and simplify alignment in compact fire pump rooms. Clarke vertical bases are engineered for exact fit and performance. Ideal for high rise buildings, retrofit applications, and installations with vertical turbine pumps.
Protection & Durability
Guards
OSHA-compliant safety guards shield operators from belts and rotating components.
Paint Options
Corrosion-resistant coatings extend engine life in coastal, humid or chemical-laden environments. Clarke's optional epoxy paint can be considered for extreme duty or harsh weather environments.
Tropicalization
Upgrades that fortify electrical and mechanical systems against high humidity and thermal cycling. Used in regions with sustained heat and prolonged periods of rain.
Enclosures
Clarke-engineered sound attenuated fire pump engine enclosures protect your engine from the elements and minimize noise. Used in outdoor pump systems and sound-sensitive areas.
