Electronic fire fighting pump is rated at what psi and what gpm

• A. 120 psi and 25 gpm
• B. 140 psi and 30 gpm
• C. 160 psi and 40 gpm
• D. 100 psi and 20 gpm

Answer: (B)

A firefighting pump is rated by the pressure it can maintain at a given flow, which defines how effectively water can be delivered through the ship’s fire mains to distant outlets. The electronic firefighting pump is rated at 140 psi with a flow of 30 gpm. This combination provides enough pressure to push water through long mains and reach outlets while sustaining a practical attack flow for initial firefighting efforts. If you use a lower rating, water won’t reach as far or as strongly; a higher pressure with the same pump would not necessarily increase usable flow and could stress hoses and fittings or reduce practical flow due to the pump’s curve.
