Jockey pumps play a crucial role in maintaining the pressure in fire protection systems, ensuring that the system is always ready to respond to a fire. This article will explain how jockey pumps function, their importance in fire protection systems, and the specific conditions under which they are most effective. We will focus on the application of jockey pumps in maintaining water pressure in fire sprinkler systems, particularly in industrial and commercial settings.
What is the Primary Function of a Jockey Pump?
A jockey pump is a small, electric pump designed to maintain the pressure in a fire protection system. Its primary function is to keep the water pressure in the system within a specified range, typically between 60-100 psi. When the system pressure drops below this range, the jockey pump activates to bring the pressure back up. This ensures that the system remains primed and ready for immediate use in the event of a fire.
How Does a Jockey Pump Work in a Fire Sprinkler System?
In a fire sprinkler system, the jockey pump works in conjunction with the main fire pump. The jockey pump continuously monitors the system pressure and automatically turns on when the pressure drops below the set threshold. It then runs until the pressure is restored to the desired level. If the jockey pump cannot maintain the pressure, it signals the main fire pump to start, providing the necessary water flow and pressure to activate the sprinklers.
Key Components and Operating Conditions
Pressure Switch: The jockey pump is controlled by a pressure switch that detects changes in system pressure.
Flow Rate: The flow rate of a jockey pump is typically much lower than that of the main fire pump, usually around 1-5 GPM.
Power Supply: Jockey pumps are usually electrically powered and require a reliable power source to ensure continuous operation.
When Should a Jockey Pump Be Used?
The use of a jockey pump is essential in any fire protection system where maintaining consistent water pressure is critical. This includes:
High-Rise Buildings: In high-rise buildings, maintaining constant pressure is crucial due to the height and the need for consistent water supply to all floors.
Industrial Facilities: Industrial facilities often have large, complex fire protection systems that require stable pressure to ensure rapid response times.
Commercial Buildings: Commercial buildings, such as shopping malls and office complexes, benefit from jockey pumps to maintain the integrity of their fire protection systems.

Frequently Asked Questions
What is the difference between a jockey pump and a main fire pump?
A jockey pump is a smaller, auxiliary pump used to maintain system pressure, while a main fire pump provides the necessary water flow and pressure to activate the sprinklers during a fire.
Can a jockey pump be used without a main fire pump?
No, a jockey pump is not designed to replace the main fire pump. It is intended to work in conjunction with the main pump to maintain system pressure.
How often should a jockey pump be inspected and maintained?
Regular maintenance is crucial for the proper functioning of a jockey pump. It is recommended to inspect and service the pump at least once every six months or as specified by the manufacturer.
