This document provides information on foam concentrate pumps and foam fire suppression systems. It discusses why foam is used to fight certain types of fires, how foam works to extinguish fires, and key questions to consider when designing a foam system, such as the size and type of hazard. It then describes foam pump systems and their advantages over bladder tank systems. These include greater flexibility and the ability to provide a sustained discharge. The document highlights features of Fire Lion foam pumps such as their lifetime warranty and field repairability. It provides examples of customer projects and concludes that Fire Lion pumps are a smart choice for foam fire suppression.

4. A FIRE THAT NEEDS FOAM !

5. Why use Foam?
Class “B” fires normally cannot be extinguished by
water alone and require foam:
• Fire Extinguishment – not just water
• Environmental damage containment
• Firefighter Safety
• Prevention of Fuel Ignition, or Re-Ignition
• Suppression of Flammable Vapors
• Post Fire Security
• Economical compared to lost value of stored
finished product.

6. What does foam do ?
Foam:
• Removes heat at a faster rate than it is released
• Separates the fuel from the oxidizing agent
• Dilutes the vapor-phase concentration of the fuel and/or oxidizing agent below
that necessary for combustion
• Terminates the chemical chain-reaction sequence

12. “SO I NEED A FOAM SYSTEM”
1. What is the size of the hazard ?
2. What is the fuel ? ( application density)
3. What is quantity of fuel ?
4. Portable or fixed system?
5. What is the least expensive way to get my foam system?
6. How long of discharge do I need?
7. What are the other risks / hazards present?
8. What are the foam system options?
Just a few of the key questions a foam system
designer must ask and know.

16. Why consider a foam pump system?
• Location of foam injection equipment cannot be
positioned near the hazard foam solution discharge
point.
• Discharge duration calculations or fuel type require a
long discharge and bladder tank becomes too large and
expensive.
• Size of hazard is large such as bulk storage tank farm,
aircraft hangars, marine flammable liquid piers,
refineries.
• End user preference and/or experience.
• Remote monitors on marine docks are far away from
foam/water system.
• Offers end user greater flexibility to quickly change foam
concentrate types or suppliers as fuel or chemical
inventory changes.

21. NFPA 20 & Foam Pumps
Key foam pump aspects of NFPA 20 standard for the installation of
stationary pumps for fire protection
2016 EDITION – CHAPTER 8
1) PUMPS SHALL BE POSITIVE DISPLACEMENT TYPE – why?
Because foam concentrate viscosity ranges from 1cps to 6,000cps – Centrifugal
pumps are not will suited to high viscosity liquids & customer fuels may change
requiring a different type of foam concentrate.
2) PACKING SHALL NOT BE USED – LIP OR MECHANICAL SEAL ONLY – why?
Foam concentrate is corrosive and slippery and expensive – So packing leaks,
common for water pumps, are not a desirable feature
3) FOAM PUMPS SHALL BE CAPABLE OF DRY RUNNING FOR
10 MINUTES – why?
Foam concentrate supply tanks are limited in size and the risk of running out of
foam is very real. The pump will likely run dry for at least 10 minutes before
responders can either turn the pump off or commence foam tank refill.

22. Foam Pump Sizing Guide
NFPA recommends the following safety factors when sizing a foam pump:
1) Design foam solution flow rate x 3% or 1% = foam flow + 20% excess pump
capacity. This ensures adequate foam concentrate flow if solution flow rates
are slightly larger than calculations AND excess flow is required to allow the
balance valve to work properly. The balance valve requires flow to balance foam
pressure to water pressure at the ratio controller.
2) Design maximum water pressure + 15 psig (1 bar) = foam pump discharge
pressure selection. This ensures that foam concentrate is injected into the water
stream in low flow conditions (fire pump is backed up on the curve) or if water
supply pressures are, in fact, higher than expected.
3) Relief valve set pressure is maximum pump pressure + 15 psig (1 bar).
4) Foam pump suction strainer hole size must account for foam concentrate
viscosities to prevent pump cavitation.

23. Foam pump flow & power curve

24. PD Foam Pump Curve is Different than
a Centrifugal Fire pump curve
When selecting the foam pump it is critical to consider the following criteria:
1) Select foam pump discharge pressure for 1 bar higher than maximum water
pressure
2) Select the foam pump capacity to be 10-15% higher than actual demand
3) Calculate foam demand by water volume x .03% for a 3% foam system or x
.01% for a 1% foam system or x .06% for a 6% system.
4) Pump curves are for 1,500 rpm ( 50 Hz electric) or 1,800 rpm ( 60 Hz electric
or diesel engine)
5) Pump drives available are: Electric motor, Diesel engine, Hydraulic motor or
Water motor ( Pelton style )
6) When selecting the driver power – consider maximum water
pressure + 1 bar = use next size up motor to account for relief valve lift.
7) A pressure relief valve is required for all positive displacement foam pumps.
