Fire protection systems operate at peak efficiency only when preventive maintenance for fire pumps is performed regularly and according to approved standards. Neglecting inspections or delaying maintenance can lead to system failure at the most critical moment, putting lives and property at serious risk. This makes routine preventive maintenance and timely system upgrades essential to ensure continuous safety and compliance with the latest NFPA and SASO requirements.
In this article, we highlight the importance of preventive maintenance for fire pumps and answer the key question: When is it necessary to upgrade your fire protection system?
We also explain how Arif Al Nahdi (ANC) provides professional maintenance and comprehensive upgrade solutions that ensure reliable performance and full readiness of your fire protection system.

What Is Preventive Maintenance for Fire Pumps?
Preventive maintenance for fire pumps is a planned program of inspections, testing, and routine servicing designed to keep fire pumps fully ready to operate according to design specifications and to reduce unexpected failures in fire protection systems.
These practices are based on NFPA 25, which serves as the primary reference standard for inspection, testing, and maintenance (ITM) of all water-based fire protection systems — including fire pumps — to ensure performance and reliability. Meanwhile, NFPA 20 defines the requirements for selecting and installing fire pumps so they operate exactly as designed during emergencies.
This approach includes scheduled visual and functional inspections, periodic performance testing, and corrective updates before faults escalate. It also follows product-certification standards such as UL 448 for centrifugal fire pumps.
The result is consistent pump efficiency, stable pressure, reduced downtime, and higher system reliability — especially in critical industrial and commercial environments.
How do we apply this at ANC?
We create a preventive maintenance plan aligned with the required inspection/testing cycles throughout the year and link it with clear performance logs to help you make early decisions regarding upgrades or replacement when needed, fully in compliance with NFPA 25 / NFPA 20 and relevant certification standards.
Types of Preventive Maintenance for Fire Pumps
At Arif Al Nahdi Company (ANC), we define preventive maintenance for fire pumps and fire systems as a scheduled inspection, testing, and servicing program that preserves readiness and prevents failures before they happen — fully aligned with NFPA 25 and installation requirements under NFPA 20.
- Weekly or monthly no-flow inspections and tests for fire pumps to ensure instant response during emergencies.
- Annual full-flow performance testing to verify the pump’s actual pressure–flow curve and overall hydraulic efficiency.
- Routine maintenance for diesel engines, batteries, and control connections according to NFPA 25 schedules and manufacturer instructions.
- Regular inspection of valves, suction sources, water tanks, and piping networks to ensure availability and remove obstructions before they cause failures.
- Documenting all inspection and testing results in official records, and managing temporary impairments through a structured action plan to reduce operational risk.
Note for Safety Managers:
When installing or upgrading UL 448 fire pumps, we first verify compliance with NFPA 20, then integrate the preventive maintenance program with NFPA 25 cycles to ensure year-round system readiness.
The Difference Between Preventive and Emergency Maintenance for Fire Pumps
Here is the practical difference we follow at Arif Al Nahdi Company (ANC) between preventive maintenance for fire pumps and systems and emergency maintenance, helping you choose the approach that preserves readiness and minimizes unplanned downtime.
| Item | Preventive Maintenance for Fire Pumps & Fire Systems | Emergency Maintenance for Fire Pumps & Fire Systems |
| Objective | Maintain system readiness through a scheduled Inspection / Testing / Maintenance (ITM) program to prevent failures before they occur. | Restore system operation after an unexpected failure or service interruption (Reactive/Breakdown). |
| Timing | Scheduled periodically (weekly / monthly / annually) based on system components and site requirements. | Unscheduled; performed when a failure impacts reliability or compliance. |
| Trigger | Compliance with reference standards (NFPA 25 for maintenance/testing, linked to proper installation per NFPA 20). | An incident, service outage, or pump/component failure alarm requiring urgent intervention to restore operation. |
| Scope of Work | Visual and functional inspections, test runs (with/without flow), annual full-flow test, diesel engine/control/battery maintenance, record-keeping, and impairment management. | Diagnosing the fault, repairing or replacing defective components, and possibly implementing temporary mitigation measures until completion. |
| Reference Standards | NFPA 25 as the main ITM standard, with optional guidance from FM Global preventive practices. | General safety guidelines and Emergency Action Plans (EAP) to protect personnel during emergency repair work. |
| Decision Indicators | Periodic test results, deviation from designed pressure-flow curve, inspection findings, aging of critical parts. | Failure alarms, sudden pressure drop, failure of pump start-up, or loss of performance. |
| Installation Requirements | Assumes installation compliant with NFPA 20 and use of certified components (e.g., UL 448 centrifugal fire pumps). | May reveal design/installation deficiencies that require corrective redesign after restoring operation. |
At Arif Al Nahdi Company (ANC), we prioritize preventive maintenance for fire pumps and fire systems through structured annual contracts that ensure year-round readiness and reliability in accordance with NFPA 20 and NFPA 25 — reducing unexpected failures across all facility types.
Key Preventive Maintenance Steps for Fire Pumps
At Arif Al Nahdi Company (ANC), preventive maintenance is a systematic process that begins with inspection and ends with documentation—ensuring maximum system readiness in full compliance with NFPA 20 and NFPA 25.
- Visual inspection of the fire pump to confirm absence of leaks, abnormal vibrations, and to verify mechanical/electrical connection integrity.
- Test-running the fire pump to confirm controller response, stable pressure, and proper flow performance during operation.
- Checking oil levels, lubrication, and motor-pump alignment to ensure smooth, efficient operation.
- Testing the jockey pump to verify its effectiveness in maintaining system pressure during normal standby conditions.
- Inspecting suction and discharge valves and supply lines to ensure proper movement and absence of blockages.
- Testing associated fire pump alarm and control systems, including manual and automatic start panels.
- Cleaning strainers and suction screens from sediment or obstructions that may impact pump performance.
- Documenting all inspection and testing results in periodic maintenance reports for future reference and follow-up.
With these routine steps, we ensure your fire pumps remain fully ready for operation at any moment and that your system stays compliant with Saudi Civil Defense requirements and international standards.
What Are the Preventive Maintenance Guidelines for Fire Pumps?
At Arif Al Nahdi Company (ANC), we follow preventive maintenance guidelines for fire pumps and fire systems as a practical framework that maintains readiness, ensures compliance, and reduces unexpected failures — all in line with NFPA 20, NFPA 25, and related certification requirements.- Follow the manufacturer’s manual along with NFPA 20 for installation and NFPA 25 for inspection, testing, and maintenance.
