Which type of fire pump is operated monthly?

• A. Diesel engine-driven
• B. Pneumatic driven
• C. Electric motor-driven
• D. Hydraulic driven

Answer: (C)

The main idea is that the frequency of exercising a fire pump depends on the drive type, and electric motor-driven pumps are the ones typically run on a monthly basis. You can simply energize the motor from the building’s electrical supply and run the pump with no flow to verify it starts promptly, reaches operating speed, and that discharge pressure and gauges respond as expected. This quick no-flow test also checks the electrical controls, relays, and alarms without needing fuel, engine startup, or engine maintenance, making monthly testing practical and effective. Diesel engine-driven pumps, on the other hand, require fuel, cooling, lubrication, and battery checks; they need more involved tests and are often exercised differently (not just a quick monthly no-flow run). Pneumatic and hydraulic driven pumps are less common, and their testing schedules follow their specific design requirements. So, monthly operation is best matched with electric motor-driven pumps.
