Fire Pump Service

A fire pump should be tested weekly and inspected annually to ensure its proper operation. Weekly testing typically involves a no-flow (churn) test, where the pump runs without discharging water, ensuring it starts and runs correctly. An annual inspection includes a full-flow test, where the pump is run at its rated capacity to verify performance. Regular maintenance, such as checking for leaks, corrosion, and proper alignment, is also essential. Following these guidelines helps ensure the fire pump operates reliably during emergencies.

The main types of fire pumps used in commercial and industrial settings are:

• Centrifugal pumps, which are the most common type, including horizontal split-case, vertical inline, and vertical turbine pumps. These pumps use rotational energy to move water.
• Positive displacement pumps, such as rotary gear and piston pumps, are used in specific applications where high pressure is required.
• Electric motor-driven pumps are widely used due to their reliability and ease of maintenance.
• Diesel engine-driven pumps are often installed as backup or in areas without reliable electrical supply.
• Jockey pumps are small pumps used to maintain pressure in the fire protection system.

Fire pump maintenance is essential for reliable performance and includes regular inspections, testing, and servicing. Monthly checks involve verifying oil levels, belt tension, and battery condition, while quarterly inspections cover valves and pressure settings. Annual tests assess the pump’s ability to maintain pressure under simulated conditions, ensuring it meets fire protection standards. Routine lubrication of moving parts and inspection for corrosion on electrical connections are also necessary. Regularly scheduled maintenance by a certified technician helps identify and address issues early, ensuring compliance with safety codes and optimal readiness.
