FAQs
Frequent jockey pump startup is usually caused by pipeline leakage, faulty check valves, pressure tank issues, or incorrect pressure switch settings. Continuous cycling may increase motor wear and reduce system stability. Regular inspection of the fire protection pipeline and pressure control system helps reduce unnecessary operation.
Dry running is not recommended for jockey pumps because it may damage mechanical seals and reduce pump lifespan. Many fire protection projects install dry-run protection devices or low-water-level alarms to improve operational safety and reduce maintenance risks.
A jockey pump is typically set slightly higher than the main fire pump start pressure to maintain stable standby pressure in the pipeline system. Actual pressure settings depend on project requirements, building height, and fire protection standards.
Fire pump rooms are often humid environments, which may accelerate corrosion of pump components and pipelines. Using corrosion-resistant materials such as stainless steel or PPO impellers helps improve long-term reliability and reduce maintenance frequency.
Routine inspection intervals depend on operating conditions and local fire protection regulations. Regular checks of pressure switches, seals, bearings, controllers, and pipeline pressure help ensure the jockey pump remains ready for continuous standby operation.
Jockey Pump for Fire Sprinkler System: Complete Guide
Fire Jockey Pump – Pressure Maintenance Pump for Reliable Fire Protection
A jockey pump (also called fire jockey pump or pressure maintenance pump) is a small but essential auxiliary pump in modern fire protection systems. Working together with the main fire pump, it maintains stable pressure in fire sprinkler systems and hydrant networks during normal operation, preventing unnecessary starts of the main fire pump and significantly extending the service life of the entire system.
Key Takeaways
- Maintains constant pressure in sprinkler and hydrant systems
- Reduces frequent cycling of the main fire pump
- Saves energy and lowers maintenance costs
- Improves overall system reliability and readiness
What is a Jockey Pump?
A jockey pump is a small auxiliary pump designed to automatically maintain the designed pressure in fire protection piping networks. It compensates for minor pressure losses caused by small leaks, temperature changes, or normal system seepage. The main function of a jockey pump is to keep the fire sprinkler system and hydrant piping at the correct pressure level during daily operation, so the main fire pump only starts during an actual fire emergency.
Jockey Pump Working Principle
When the system pressure drops below the preset value, the jockey pump pressure switch automatically starts the pump. Once the pressure returns to the normal range, the pump stops. This cycle prevents frequent starting of the main fire pump, saves energy, reduces mechanical wear, and extends the service life of the entire fire fighting system. Most jockey pumps are electric-driven for quick response and reliable daily operation.
Jockey Pump vs Fire Pump
Jockey pump and fire pump serve different roles in the system. The jockey pump is small and used for daily pressure maintenance, while the main fire pump is larger and designed to deliver high flow rates during fire emergencies. Understanding the difference between jockey pump vs fire pump helps engineers select the right equipment for each project.
| Comparison Item | Jockey Pump | Main Fire Pump | Benefits |
|---|---|---|---|
| Capacity | Small (1-10 m³/h) | Large (50-500+ m³/h) | Energy conservation and wear reduction |
| Purpose | Daily pressure maintenance | Emergency high-flow supply | Lengthen system lifespan |
| Operation Frequency | Frequent but short | Rare (fire or test only) | Reduce maintenance costs |
| Power Source | Usually electric | Electric + Diesel | Multiple safeguards |
| Dry-run Protection | Highly recommended | Critical | Improve system safety |
How Fire Pump and Jockey Pump Systems Work
In a standard fire protection system, the jockey pump and main fire pump work together to ensure both daily stability and emergency readiness. Under normal conditions, the jockey pump maintains the required pipeline pressure. When minor pressure drops occur due to small leaks or temperature changes, only the jockey pump starts. If the pressure drops significantly (such as during a fire event), the main fire pump automatically activates to deliver large volumes of water. The jockey pump controller and fire pump controller coordinate to manage automatic operation, alarms, and system monitoring.
Jockey Pump Piping Diagram and Installation
A typical fire pump and jockey pump piping diagram includes pressure switches, check valves, relief valves, bypass lines, and isolation valves. Proper jockey pump installation ensures smooth operation, easy maintenance, and system safety. Correct piping design prevents backflow and allows the jockey pump to work efficiently with the main fire pump. Many projects use a jockey pump diagram during the design phase for accurate engineering and installation.
Types of Jockey Pumps
We offer two specialized series designed for different project needs: the SVP PPO Jockey Pump and the CDL SS Jockey Pump.
SVP PPO Jockey Pump
Compact horizontal model with PPO (Polyphenylene Oxide) impellers and diffusers. Features excellent corrosion resistance, low noise, energy efficiency, and lightweight design. Ideal for commercial buildings, residential communities, and projects with limited installation space.

Selection Tips for Fire Jockey Pumps:
Choosing the right jockey pump, whether SVP, PPO or CDL SS type, should be based on building scale, pipe network volume, required maintenance pressure, local fire codes, and coordination with the main fire pump. A well-selected jockey pump ensures the fire water supply system remains always ready, safe, and efficient.
Key Factors When Buying a Jockey Pump
When selecting a jockey pump (pressure maintenance pump) for a fire sprinkler system, it is important to consider more than just price. The right choice directly affects system reliability, energy consumption, and long-term maintenance costs.
Here are the most critical factors to consider:
-
NFPA 20 Compliance & Certifications
Always choose a jockey pump that meets NFPA 20 and relevant local fire codes. This ensures the pump is approved for fire protection use and passes inspections smoothly.
-
Correct Sizing & Performance Matching
The jockey pump should have small flow rate (typically 1-10 m³/h) but sufficient head pressure (usually 0.1–0.2 bar higher than the main fire pump’s start pressure). Oversized or undersized pumps will cause frequent cycling or fail to maintain pressure.
-
Material & Corrosion Resistance
Fire pump rooms are often humid. Prioritize models with strong corrosion resistance:
-
SVP PPO Jockey Pump:
PPO impellers + engineering plastics (lightweight, cost-effective)
-
CDL SS Jockey Pump:
Full stainless steel construction (best for humid or slightly corrosive water)
-
Automatic Control System
Look for a reliable jockey pump controller with pressure switches, automatic start/stop, alarms, and preferably remote monitoring capability. Good coordination with the main fire pump controller is essential.
-
Installation Space & Noise Level
Vertical multistage pumps (like CDL SS) are ideal for limited space. Low-noise design is especially important for hospitals, hotels, and residential buildings.
-
After-Sales Support & Spare Parts
Choose a supplier that provides performance curves, factory test reports, quick spare parts availability, and strong technical support.
-
Buying Tips：When buying a jockey pump, always verify certifications, review real performance curves, and ensure strong after-sales support. Prioritizing reputable models like SVP PPO and CDL SS will help you build a safer and more efficient fire protection water system.
Common Mistakes When Buying a Jockey Pump
Choosing the right Jockey Pump is critical for maintaining stable pressure in fire protection systems. Avoiding these common mistakes will help you select a reliable, long-lasting pressure maintenance pump and reduce future operational risks.
Choosing Price Over Quality
Many buyers opt for the cheapest Jockey Pump to save initial costs. However, low-priced models often use inferior seals, weaker impellers, and lower-grade materials. This leads to frequent breakdowns, higher maintenance costs, and reduced reliability of the entire fire water supply system.
Ignoring Certification and Compliance
Some projects overlook whether the jockey pump complies with NFPA 20 or local fire codes. Non-compliant pumps may fail during inspections or emergencies, resulting in serious safety risks and project delays.
Incorrect Sizing and Model Selection
Using an oversized or undersized Jockey Pump is a frequent mistake. An undersized pump cannot maintain proper pressure, while an oversized one causes unnecessary energy consumption and frequent cycling. It is essential to match the flow and head precisely with the main fire pump and pipe network volume.
Neglecting Materials and Corrosion Resistance
In humid fire pump rooms, using pumps with poor corrosion resistance (such as ordinary cast iron models) leads to rapid rusting and leakage. Choosing proper materials like PPO impellers (SVP PPO Jockey Pump) or full stainless steel (CDL SS Jockey Pump) is crucial for long-term durability.
Skipping Proper Testing and After-Sales Support
Some buyers forget to verify real performance curves or factory testing reports. Additionally, choosing brands without strong local after-sales support makes future maintenance and spare parts difficult to obtain.
