    Overview for Tiger Supplies 100105 MK3-U High-Pressure Wildland Fire Pump

    Firefighting is a serious job that calls for a serious fire pump. The WaterAx MK3-U Mark-3 High-Pressure Wildland Fire Pump is a seriously powerful fire pump that, since its release in 1964, has become the most trusted portable pump for wildland fire crews around North America. At the core of most remote water delivery systems in wildland fire suppression, the Mark-3 pump is known for being incredibly lightweight yet powerful enough to consistently deliver high-pressure output over longer distances and higher elevations, pump in tandem or series, and withstand the physical demands of firefighting. 

    Most powerful, portable fire pump. The Mark-3 pump combines a WaterAx 185cc 2-stroke 10 hp engine and a detachable, maintenance-free 4-stage centrifugal pump end. The result is a powerful unit that can deliver pressures of up to 380 PSI and flow rates of up to 98 GPM. When the water is pumped upwards, it can reach up to a staggering 878 feet. This level of performance is crucial for firefighters on the ground who need to move water over long distances in difficult terrain. It is a true workhorse that excels in direct attack wildfire operations, high-elevation firefighting in mountainous areas, in-series pumping over long distances, and more. 

    Lightweight and durable build. The 2-stroke engine of this pump gives it an unmatched power-to-weight ratio, and with a backpackable frame, it can be easily carried and transported by foot. It also has aluminum alloy components and anodized parts that are not only lighter but also offer greater resistance to corrosion. After a series of upgrades in 2015, the Mark-3 fire pump now has a detachable maintenance-free pump end, an impregnated crankcase, and a Nikasil coated cylinder. The pump end with a quick-release clamp lessens equipment downtime in the field, and the sealed bearing effectively removes pump end greasing. The Nikasil coated cylinder is known for better wear-resistance than the cast iron sleeve cylinders of old Mark-3 models. The recommended fuel mix ratio has also been adjusted to 50:1 synthetic. 

    Certifications. The upgraded version successfully passed the USDA Forest Service 100 hours endurance test in San Dimas on 08/04/15 and has been requalified under QPL Number 274-001. Mark-3 meets or exceeds USDA Forest Service Specification 5100-274E and is exempt from emission standards under 40 CFR 1054.660. 

    MK3-U Configuration. The Mark-3 fire pump is available in several configurations, one of which is the MK3-U configuration that comes with an SAE 45 fuel connector, a fuel line, a discharge thread protector, and a suction thread protector. It does not come with a fuel tank. 

    Reliable, lightweight, and powerful, the WaterAx MK3-U Mark-3 High-Pressure Fire Pump is the ultimate portable fire pump you need for suppressing wildland fires.
