Each AFFF Transfer System Station pumps is rated at how many GPM's?

• A. 120
• B. 240
• C. 360
• D. 480

Answer: (C)

Understanding pump flow helps you see why this rating makes sense: the GPM rating tells you how much foam solution the pump can move each minute. In an AFFF Transfer System Station, each pump is sized to reliably feed the foam distribution network—through lines and eductors or proportioners—without starving the system or wasting energy. A rating of three hundred sixty gallons per minute provides enough flow to support the foam transfer and proportioning needs of a station, even when multiple paths are drawing foam or when the system operates at the required pressures. If the pumps were rated much lower, the system could struggle to deliver adequate foam flow; if they were rated much higher, you’d be pushing more water than necessary, wasting horsepower and increasing wear. You can confirm the actual rating by checking the pump nameplate or the station’s technical documentation, which reflects the designed capacity for each pump.
