In fire protection systems, ensuring consistent water pressure is crucial for the effective operation of fire sprinkler systems. This is where jockey pumps come into play. Although they are small, their role in maintaining the stability and reliability of fire protection systems cannot be overstated. This article explores the functionality and importance of jockey pumps, how they work with fire pumps, and why Purity PVT jockey pumps stand out as a top choice for many industrial and commercial applications.

A jockey pump is a small auxiliary pump designed to maintain water pressure in fire sprinkler systems. Its primary function is to keep the system’s pressure stable and prevent the main fire pump from being activated unnecessarily. This helps to avoid false alarms and ensures the fire pump only turns on when there's a significant pressure drop, typically when a sprinkler is triggered during a fire.
Jockey pumps for fire sprinkler systems are crucial in locations where maintaining high and consistent pressure is a must, such as in high-rise buildings, industrial plants, commercial buildings, and storage facilities. They ensure that the sprinkler system remains operational even if minor leaks or temperature fluctuations cause slight pressure drops. By preventing unnecessary activation of the fire pump, jockey pumps also help reduce the wear and tear on the system and minimize energy consumption.
The jockey pump for sprinkler system works by monitoring and adjusting the pressure in the fire protection system. When the pressure drops below a set threshold, the jockey pump kicks in to restore the pressure. This is particularly important because any small pressure loss—whether from a minor leak or temperature changes—could cause the fire pump to start unnecessarily, wasting energy and potentially damaging the system.
By maintaining the pressure within the required limits, the jockey pump fire pump ensures the entire system stays ready for action, without unnecessary disruptions or false activations. The jockey pump operates continuously, keeping the pressure stable without triggering the larger fire pump unless there is a real need, such as a significant drop in pressure caused by the opening of a sprinkler head.
A key aspect of a fire protection system is the synergy between the jockey pump and the main fire pump. While the jockey pump is responsible for maintaining the system’s pressure under normal conditions, the fire pump steps in during emergencies to provide the necessary high flow and pressure for the sprinkler system to operate effectively.
In a fire sprinkler system, the jockey pump keeps the pressure at a level that allows the fire pump to remain off until there is an actual need, such as when a sprinkler head is activated during a fire. The fire pump jockey prevents unnecessary cycling of the main pump, ensuring it only operates when required. This collaboration ensures that the system operates efficiently, using less energy and providing maximum protection when it's needed most.
There are several types of jockey pumps, each suited for different applications:
（1）Regenerative Turbine Pumps: These are inexpensive and have low horsepower. While they are less costly, they require a pressure relief valve to manage pressure levels effectively.
（2）Vertical Multi-stage Pumps: These pumps are highly reliable and able to handle higher pressures. They are ideal for systems that require precise pressure control and are easy to maintain. They are slightly more expensive but are known for their durability and efficiency.
（3）Submersible Multi-stage Pumps: These pumps are typically used when water pressure from the source is not sufficient. They are submerged in water and are commonly used in systems that require additional pressure for optimal performance.
Each of these types can be used in different scenarios depending on the system’s requirements and the building’s layout. The correct type of jockey pump for fire sprinkler system ensures that the system operates without issues and maintains optimal pressure.
When selecting a jockey pump, it is important to consider the quality and performance of the equipment. Purity PVT jockey pumps offer several distinct advantages over other models on the market:
（1）Durability and Corrosion Resistance: Purity PVT jockey pumps are built with hard alloy and fluororubber mechanical seals, making them resistant to corrosion, high temperatures, and deformation. This ensures a longer lifespan and reduced maintenance costs compared to other pumps.
