Which activities are routine maintenance tasks for fire pumps?

• A. Visual inspections, lubrication, belt tensioning if applicable, controller checks, priming checks, and running tests.
• B. Belt replacement every week.
• C. Visual inspections and lubrication only.
• D. Running tests exclusively.

Answer: (A)

Routine maintenance for fire pumps focuses on keeping the unit ready to perform under demand by addressing mechanical condition, the drive system, controls, priming readiness, and functional testing. The best choice reflects a comprehensive set of tasks: visual inspections to spot leaks, corrosion, loose parts, or wear; lubrication to reduce friction and wear on bearings and moving components; belt tensioning if the installation uses belts to prevent slip and uneven wear; controller checks to verify automatic starting logic, alarms, interlocks, and power supplies are all functioning; priming checks to ensure the pump can develop and maintain prime so it won’t lose prime when called upon; and running tests to confirm the pump starts, delivers the required flow and pressure, and that the control sequence and alarms operate correctly. The other options don’t provide a complete, practical maintenance approach. Replacing belts weekly is unnecessary in most systems, and routine maintenance typically emphasizes inspecting and adjusting as needed rather than replacing belts on such a frequent schedule. Limiting maintenance to only visual inspections and lubrication omits critical elements like drive alignment, belt condition, control system checks, priming readiness, and performance testing. Relying on running tests alone ignores ongoing preventive measures that keep the system reliable between test cycles.
