Top Tier Performance
The Husky™ Industrial foam system is designed to deliver a level of performance that's unsurpassed. Its foam pump has capacities up to 300 gallons per minute and is capable of supporting a 5,000 gpm discharge rate while using a 6-percent foam concentrate. This unique, patented, digitally controlled foam proportioning system responds rapidly and accurately to changes in water pressures and flows.
What is a non-recirculating automatic pressure-balanced system? Foam concentrate does not recirculate back to the foam tank. Foam concentrate pressure is automatically balanced to equal water pressure.

The Essentials
- Designed for Class B foams exclusively.
- Electronic digital foam proportioning system improves responsiveness, reliability, and accuracy through a range of 75 PSI to 250 PSI.
- On-demand design ensures no foam is bypassed back to the foam tank or recirculated through the foam pump.
- Clean-up is easy because each discharge outlet features its own metering valve. The operator needs only to flush the discharge lines used.
- Flexible foam pump drive systems are engineered to run from either a pump transmission or PTO system, depending on customer needs. With the PTO-driven system, foam transfer operations are easy because there is no need to engage the water pump during foam discharge.
- Foam systems are capable of using the vehicle's water tank, high-pressure hydrant or draft as a water source.
- Foam systems can draft foam concentrate from an outside source, allowing extended foam operation.
Uses a lower electrical load, helping to create a lower-cost system that requires less power from the chassis, and prevents overload during tough fire calls. Husky™ is the only municipal-market foam system with this feature.

CAPACITY
The Husky™ 160 system is best applied for water pump capacities between 1,500 GPM (5,678.12 LPM) and 2,000 GPM (7,570.82 LPM), which will typically flow approximately 2,300 GPM (8,706.45 LPM) and 3,100 GPM (11,734.78 LPM) respectively at 80 PSI dynamic hydrant pressures. However, when flowing greater than 2,286 GPM (8,653.45), you will be restricted to a 3% foam.
- 1.3%=160GPMx100GAL/1.3GAL=12,308GPM
- 1.3%=605.67LPMx378.54L/4.92L=46,599.66LPM
- 3.9%=160GPMx100GAL/3.9GAL=4,103 GPM
- 3.9%=605.67LPMx378.54L/14.76L=15,533.22LPM
- 7.0%=160GPMx100GAL/7.O GAL=2,286GPM
- 7.0%=605.67LPMx
The Husky™ 300 system is required for water pumps that are in the 2,500 GPM (9,463.53 lpm) to 3,500 GPM (13,248.94 lpm) range. When using a high flow device, you will not be able to flow foam through any other outlet when metering foam at a 6% setting.
- Husky™ 300 capacity at the metering valve setting +30%
- 1.3%=300GPMx100GAL/1.3GAL=23,O77 GPM
- 1.3%=1,135.62LPMx378.54L/4.76L=90,310.42LPM
- 3.9%=300GPMx100GAL/3.9GAL=7,692 GPM
- 3.9%=1,135.62LPMx378.54L/1
SAFETY
- Uses a lower electrical load that requires less power from the chassis and prevents overloading during tough fire calls.
- Patented digital electronics accurately control foam pressure, and "soft start logic" programming preventing damaging foam pressure spikes at start-up.
- Experience quicker knockdown, resulting in less time spent at the fire.
- Reduced water damage to the structure because you're using only half the water needed to extinguish the fire.
