In a fire pump test report, which item describes the pump’s capacity?

• A. Age of the system
• B. Pump rating
• C. System it supplies
• D. Type and rating of the driver

Answer: (B)

The ability of a fire pump to move water, its capacity, is defined by the pump rating. The pump rating states the flow the pump is designed to deliver (often in GPM) at a specified discharge pressure or head. In a test report, this rating communicates the pump’s actual capacity, independent of what powers it or which system it serves.

Age of the system is not related to how much water the pump can move. The system it supplies describes which system is being fed, not the pump’s performance. The type and rating of the driver tells you what powers the pump (electric motor or diesel) and its electrical or fuel requirements, but it does not change the pump’s capacity itself.
