ISUZU : UNDERMOUNT WATER TANK

Based on 2025 Isuzu D-MAX 4×4 Single Cab. Body can also be fitted to a wide range of chassis including Toyota Land Cruiser VDJ79, Toyota Hilux, Ford Ranger, and more.

Vehicle Platform 

• 2025 Isuzu D-MAX 4×4, 3.0 L turbo diesel engine, automatic transmission 

• ARB bullbar with integrated winch capability for enhanced off-road protection and recovery operations 

• ARB GVM upgrade for increased payload capacity, allowing additional firefighting gear and supplies 

Lighting & Power 

• Full Hella LED lighting system—robust, energy-efficient illumination for day-night visibility  

• Code 3 emergency lighting for rapid-response compliance with siren-integrated strobe lighting  

• Dual-battery system ensures redundant power supply for critical systems (lighting, pump, foam system) even under high load 

Control & Monitoring 

• Cab engine controls allow pump engagement, throttle   adjustment, and foam system activation directly from within the cab  

• Electronic water level gauges located in both the rear console and cab dashboard provide real-time tank monitoring 

Canopy & Storage 

• Centurion roller shutter provides quick access to equipment while protecting contents during transit 

• Under-canopy mounting of water tank leaves full canopy area available as dry storage for tools, hoses and other gear 

• Easy-clean deck design: all components elevated from deck surface, simplifying wash-down and maintenance tasks 

 Design & Construction 

• Low centre of gravity ensures superior stability and handling in rugged terrain 

• All stainless-steel pipework, offering corrosion resistance and service longevity 

• Colour-coded piping minimizes confusion and expedites operation under pressure 

• Precision-engineered with maintenance in mind—for easier servicing and enhanced operational reliability 

Water & Pumping System 

• 500 L low-centre water tank, mounted beneath the canopy to significantly lower centre of gravity and free canopy space 

• GAAM MK 70 diesel water pump: Flow capacity up to 850 L/min, Pressure up to 720 kPa, bronze impellers, lightweight alloy casing, replaceable bronze wear rings, mechanical seal 

• Quenchmaster Foam Injection System (Class A only): Flow range 200–1500 L/min, Operating pressure 600–1000 kPa, Foam proportioning 0.1%–1% Class A, Automatic flush function 

• Aluminium hose reel: 20 m × 25 mm hose for quick deployment 

• Two stainless-steel, colour-coded deliveries for rapid deployment and easy operator identification 

• Standpipe fill port for hydrant refilling 

• Suction coupler fill for drafting from static sources (dams, tanks) 

Key Advantages 

• High-performance water delivery: MK 70 pump provides up to 850 L/min at 720 kPa 

• Foam- enhanced suppression: Class A foam proportioning system (0.1–1%) improves water penetration and firefighting effectiveness 

• Superior mechanical resilience: pump and pipework built with corrosion-resistant alloys and stainless steel 

• Operational safety and efficiency: automatic foam system flush, electronic tank monitoring, and in-cab controls for full situational control 

• Optimal storage-to-function ratio, with canopy free for dry equipment thanks to sub-frame tank design 

• User-friendly and service-efficient design, from elevated deck components to intuitive control access
