A lightweight piercing system for UHP firefighting consisting of a water-turbine- driven pressure amplifier (weighing less than 40-pounds and having no greater dimension than 16.5 inches) and a handheld gun.   The system will not use any electrical or wireless components.

The piercing gun will utilize suction for abrasive garnet mixing.  Mixing will take place at the end of the gun barrel and not require abrasive to be “pushed”, as a high-speed wear element, through any hose or extremity external to the gun.  The abrasive material will be housed in a quick-change magazine.  The magazine will be an integral component of the gun shoulder-stock. 

The turbine-driven pressure amplifier will weigh less than 40-pounds and will be equipped with a 1.5 to 2.5 inch interchangeable inlet hose fitting.  The supply water from the fire engine will spin a turbine that directly drives a high-pressure pump.  Handline flow will power the pressure amplifier and will not require a separate power source (electric, diesel, gasoline, or PTO).
