MARK-3® Watson Edition Fire Pump with Integrated Fuel Tank

The MK3-WW is purpose-built to deliver exceptional portability and endurance for wildland firefighting operations. Its integrated 1 US gallon (3.8 L) fuel tank provides up to ~45 minutes of uninterrupted runtime at full throttle - 100% and ~65 minutes at 75% throttle, allowing crews to stay focused on suppression efforts instead of refueling.

When operations extend beyond the initial attack, a three-way fuel valve enables quick, seamless connection to an external fuel source-ensuring continuous power exactly where and when it’s needed. Designed for demanding field conditions, the MK3-WW combines rugged protection, lightweight mobility, and reliable performance to support both rapid deployment and sustained operations in remote terrain.
