2023年5月12日 · An AFFF or Class A type foam is a great example of this. When dealing with SFFFs, these foams are Non-Newtonian (do not flow and act like water). These foams require a different style of pump that can handle the viscosity range of any foam agent on the market.

Portable foam concentrate transfer pumps are essential for transferring foam concentrates from pails, drums, totes, or bulk shipments into atmospheric tanks or vice versa. Many configurations are available, including two- or four-wheeled push carts, carry handles, electric motors, and gasoline or diesel engines.

Gear-type positive displacement pumps are used for pumping foam concentrate (AFFF, AR-AFFF, FP, FFFP, High Ex, SFFF, etc.). They are the only type that works effectively in foam systems. Foam concentrate pumps are integral to fire suppression systems for many applications, including—but not limited to—the petroleum, oil and gas (POG ...

Single-speed pumps, which are rated at 12, 27 and 60 gpm and inject their rated capacity of concentrate into the seawater firemain. The 12-gpm single-speed pump is a low-capacity system, while the other two are high-capacity systems. High-capacity AFFF proportioning systems are installed on ships that require large quantities of AFFF to

Chemguard develops and produces fire suppression foams, equipment, and systems, specialty foam pumps, and fluorosurfactant specialty chemicals for demanding applications around the globe.

AFFF foam concentrate are designed for rapid fire knockdown by producing a thin aqueous film which helps to prevent the release of fuel vapours. The foam blanket, from which the film forming liquid drains separates oxygen from the fuel surface, extinguishes the fire and prevents re-ignition.

starting the afff concentrate pump on slow and opening the hycheck and powercheck valves as well as energizing the sopv for the low flow rate group (minus hose reels)

2023年12月7日 · These foams require a different style of pump that can handle the viscosity range of any foam agent on the market. Gear pumps are the pumps designed for higher viscosity, and non-Newtonian fluids like SFFFs. Fire Lion has …

Chemguard 6% AFFF Military Spec is a specially formulated synthetic aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket.

2002年8月18日 · dcfa, there is no difference in pumping Class B or AFFF either through a crash truck or a structural pumper. AFFF is corrosive over time and we have never had a pump fail certification due to...
