In a fire pump system, the jockey pump (pressure maintenance pump) ensures stable system pressure and prevents unnecessary starting of the main fire pump. Correct jockey pump sizing is essential for system reliability and compliance with NFPA 20. Below are the established engineering recommendations for selecting jockey pump flow and pressure: 1. Jockey Pump Flow: Approximately 1% of the Fire Pump Rated Flow A widely accepted engineering guideline is: Jockey Pump Flow ≈ 1% of Fire Pump Capacity Example: Fire Pump Capacity: 1000 GPM Jockey Pump Flow: 1% × 1000 GPM = 10 GPM This compensates for normal system pressure loss caused by minor leaks, thermal contraction, or valve seepage—without being large enough to satisfy real fire demand. 2. Jockey Pump Pressure: +10 PSI or +10–20 PSI Depending on Application NFPA 20 does not specify an exact pressure requirement; however, engineering practice has formed two commonly used rules: A. Standard Recommendation: +10 PSI Jockey Pump Pressure = Fire Pump Rated Pressure + 10 PSI This is suitable for:✔ Low-rise commercial buildings✔ Small to mid-size sprinkler systems✔ Stable, low-pressure fire protection networks✔ Projects with minimal static pressure fluctuation This “+10 PSI rule” is widely referenced in pump manuals, design guides, and UL/FM installation documentation. B. Engineering Recommendation for Complex Systems: +10–20 PSI Jockey Pump Pressure = Fire Pump Pressure + 10 to 20 PSI This range is used in more demanding applications, where a fixed +10 PSI may be insufficient. Applicable scenarios include:✔ High-rise buildings with large static pressure variation✔ High-pressure or multi-zone fire protection networks✔ Industrial systems (oil & gas, power plants, manufacturing)✔ Long-distance pipe networks with greater pressure loss✔ Systems experiencing water hammer or nighttime pressure drops✔ Projects requiring tighter control of fire pump start-up logic The additional pressure margin ensures: Stable pressure maintenance Prevention of nuisance fire pump starts Reliable operation in dynamic hydraulic environments 3. Why Proper Jockey Pump Selection Matters Correct jockey pump settings ensure system reliability by: Maintaining stable network pressure Preventing unnecessary fire pump activation Reducing wear on fire pumps, drivers, and controllers Ensuring NFPA 20–compliant pressure sequencing Enhancing overall fire protection system performance Improper selection may cause false starts, pressure instability, or even failure of the fire pump to activate correctly during an actual fire. 4. NMFIRE Support NMFIRE offers complete technical assistance for selecting jockey pumps matched to our UL/FM certified fire pump systems. From low-rise commercial buildings to high-pressure industrial facilities, our engineering team helps ensure optimal pressure control and full compliance with international standards.

The difference between a fire pump and a normal water pump is fundamental. Fire pumps are governed by strict international standards—primarily NFPA 20, UL 448, and FM 1311—because they are responsible for life safety. These standards dictate how the pump must operate under unpredictable fire conditions, ensuring it performs reliably when demand is at its worst. Below are the essential engineering differences: 1. System Operation: Controlled vs. Uncontrolled Flow Conditions A normal water pump system operates in a controlled hydraulic environment. Valves are adjusted to ensure the pump runs near the Best Efficiency Point (BEP). Flow and pressure are stable and predictable based on system demand. A fire pump system follows a completely different logic: Discharge and suction valves must remain fully open at all times as required by NFPA 20. Flow is uncontrolled because a fire event is unpredictable—the system must instantly deliver whatever flow the demand-side requires. Fire pumps cannot be throttled for performance or energy efficiency; safety overrides efficiency. In other words, a normal pump is optimized for efficiency; a fire pump is optimized for absolute reliability during emergencies. 2. Duty Point Predictability vs. Full-Curve Reliability Requirement A normal water pump is selected based on a known duty point. Its operation is stable and usually stays close to BEP. Fire pumps, however, only have a rated point—but the actual operating point during a fire may fall anywhere on the curve. NFPA 20 and UL/FM testing require the pump to be stable and safe across the entire operating range, including: Shutoff (0% flow) – must not exceed maximum allowed churn pressure. Rated flow (100%) – must meet certified pressure. Overload flow (150% of rated) – must still deliver at least 65% of rated pressure. Because firefighters may open multiple hoses, hydrants, or sprinklers simultaneously, the pump may operate beyond 1.5Q under real emergency conditions. Therefore, a fire pump must be engineered to avoid failures such as cavitation, shaft overload, excessive vibration, or motor overcurrent anywhere on the curve, not just at one point. 3. Power Curve Requirements: A Critical Safety Factor Unlike normal pumps, fire pumps have strict power performance requirements. UL/FM certification mandates: The entire pump performance curve must be accompanied by a full power (BHP) curve. The Max BHP point must be clearly indicated. The selected driver (electric motor or diesel engine) must exceed the Max BHP, ensuring the pump can operate safely at any load—including overload conditions. In practical engineering terms: “The fire pump driver must never be the limiting factor during a fire.” For pumps with the same design point: The pump with a lower Max BHP requires a smaller motor or diesel engine. This results in lower equipment cost, lower controller cost, and lower operating stress. This is why high-quality manufacturers optimize hydraulic design to keep Max BHP as low and stable as possible.

We have successfully completed the testing of our newly developed two-stage split case fire pump, engineered specifically for high-pressure fire protection applications. This new model delivers exceptional performance across multiple operating conditions: 1500 GPM at 22–32 bar at 2100 rpm 1500 GPM at 18–22 bar at 1760 rpm The pump is now entering the final phase of approval, and we expect to obtain UL/FM certification very soon. With this addition, the NMFIRE two-stage pump range now covers:500–1500 GPM at 18–42 bar,making it suitable for a wide range of demanding high-pressure fire protection projects across industrial, municipal, and special-hazard environments.

In the world of fire protection, there is no second chance—only the highest standards and the most reliable solutions deserve to be trusted. Just as our equipment is engineered to perform in the most demanding environments, every fire pump we design has one unwavering purpose: to safeguard what truly matters.

Differernce between fire pump and normal water pump:1: The system is totally differentNormal water pump's system is under control by discharge valve to running at best efficiency point areaFire pump's system is a free system, the discharge valve and suction valve are fully open anytime, as we don't know when the fire will be come2: Normal water we know the duty point and pump will be runnig at this duty point too (Usually is near the best efficiency point)Fire pump we only have the design point, but we can't predict the exact point on the curve when the fire pump will be running during a fire. Therefore, we must ensure the fire pump operates safely at any point on the full curve (Including the area where the flow exceeds 1.5Q)3: The power curve is totally differentUL/FM and NFPA20 standards require the pump suppliers to provide the fire pump curve with the full range of flow and powercurve showing the Max BHP(Brake Horsepower)Additionally, when the driver power bigger than the Max BHPof the fire pump, you can running the pump safely under any condition of pump load.For the same design point pump, who have lower Max BHP, who will get lower cost for their fire pump's package
