Diesel fire pumps are selected because they can operate when electrical power is unreliable. That advantage only remains true if the engine and controller are maintained correctly.
Routine checks should include fuel level, battery status, oil level, coolant condition, controller alarms, pipe leakage and room ventilation.
Periodic test running helps confirm startup reliability and allows operators to identify abnormal vibration, noise or temperature before an emergency.
Spare parts and service records should be kept near the pump room so maintenance teams can act quickly.
