April 29, 2025
Introduction
In any fire fighting system, reliability is non-negotiable. A critical but often overlooked component of this reliability is the jockey pump. Designed to maintain pressure in the fire protection system, jockey pumps ensure that the main fire pumps are only activated during an actual emergency. Whether you are managing a skyscraper, an industrial complex, or a residential community, understanding the common problems in jockey pumps and how to troubleshoot them is essential to guarantee system performance and save lives.
In this detailed guide, the experts at DFS, the exclusive distributor of NMFIRE products in Saudi Arabia, share professional insights into jockey pump issues, troubleshooting techniques, and best practices for maintaining your fire fighting pumps.
What Is a Jockey Pump?
A jockey pump is a small centrifugal pump connected to a fire fighting system. Its primary function is to maintain pressure in the sprinkler piping, preventing unnecessary activation of the main fire pump due to small leaks or pressure drops. By doing this, it prolongs the life of the larger, more expensive fire fighting pumps.
Companies like NMFIRE, known for their innovative fire pump solutions, emphasize the importance of a properly functioning jockey pump to ensure an efficient and cost-effective fire protection strategy.
Importance of Jockey Pumps in Fire Fighting Systems
A robust fire fighting system in Saudi Arabia or anywhere else must ensure immediate pressure delivery during an emergency. Here’s why a jockey pump is critical:
- Prevents main pump overuse
- Maintains steady pressure
- Detects leaks early
- Reduces energy costs
- Increases fire system reliability
Choosing high-quality brands like NMFIRE and working with reliable partners such as DFS ensures long-term efficiency and protection.
Common Problems in Jockey Pumps
Understanding the potential issues in jockey pumps helps in faster detection and repair. Let’s explore:
1. Jockey Pump Fails to Start
Possible Causes:
- Power supply issues
- Faulty pressure switch
- Motor failure
- Wiring problems
- Control panel malfunctions
Troubleshooting:
- Check the power source to ensure proper voltage and connection.
- Inspect the pressure switch — it could be stuck or miscalibrated.
- Test the motor separately to confirm functionality.
- Examine wiring and relays for loose connections.
- Review control panel settings; replace defective components.
2. Jockey Pump Runs Continuously
Possible Causes:
- System leaks
- Incorrect pressure settings
- Faulty pressure switch
- Valve problems
Troubleshooting:
- Conduct a leak test on piping and valves.
- Verify pressure settings align with system design requirements.
- Replace or recalibrate the pressure switch.
- Inspect all valves for proper sealing.
3. Frequent Short Cycling
Short cycling refers to the jockey pump frequently starting and stopping within short periods.
Possible Causes:
- Pressure switch hysteresis set too narrow
- Small leaks in the system
- Oversized jockey pump
Troubleshooting:
- Adjust pressure switch settings to allow a broader differential.
- Fix any detected leaks immediately.
- Check jockey pump sizing — consult experts like DFS for system-appropriate sizing.
- Automatic Pump Activation: Ensures that the fire pump starts immediately upon detecting a pressure drop.
- System Reliability: Reduces the risk of system failure during a fire.
- Compliance and Safety: Meets national and international fire safety regulations.
- Energy Efficiency: Optimized operation minimizes energy consumption and maintenance costs.
4. Loss of Pressure in the Fire Fighting System
Possible Causes:
- Faulty non-return valve
- Pump performance degradation
- Worn impellers
Troubleshooting:
- Inspect the check valve for dirt, debris, or mechanical failure.
- Measure jockey pump performance (flow vs. pressure).
- Replace worn or damaged impellers with genuine parts like those from NMFIRE.
5. Overheating of the Pump Motor
Possible Causes:
- Continuous running without rest
- Electrical faults
- Blocked ventilation
- Incorrect motor size
Troubleshooting:
- Ensure proper pump cycling.
- Conduct an electrical system inspection.
- Clean motor ventilation.
- Confirm motor sizing for the load.
How to Maintain a Jockey Pump: Best Practices
Proactive maintenance is critical for ensuring that your jockey pump supports the fire fighting system when needed. Here’s how:
Scheduled Inspections
- Weekly checks of pump starting and stopping
- Monthly performance testing
- Quarterly system pressure verifications
Calibration and Testing
- Annual recalibration of pressure switches
- Flow testing to validate pump efficiency
- Use expert services like those offered by DFS to ensure thorough inspections and maintenance.
Quality Parts and Upgrades
- Always use genuine NMFIRE parts for replacements.
- Consider upgrading to smart jockey pumps with remote monitoring capabilities, especially for large facilities in cities like Riyadh and Jeddah.
