Difference between a jockey pump and a fire pump


 A jockey pump and a fire pump are two different types of pumps used in fire protection systems. Here are the main differences between them:


Jockey Pump: A jockey pump is a small pump that is used to maintain the pressure in a fire protection system. It operates continuously and helps compensate for minor leaks or pressure drops in the system. Its main purpose is to keep the system pressurized within the desired range.

Fire Pump: A fire pump, on the other hand, is a larger pump specifically designed to provide a significant flow of water to the fire sprinkler system or other fire protection systems. Its purpose is to deliver a high volume and pressure of water to control or extinguish fires in buildings or structures.


Jockey Pump: Jockey pumps are typically smaller in size and have lower flow rates. They are usually designed to provide a constant and relatively low flow of water, often in the range of tens to hundreds of gallons per minute (GPM).

Fire Pump: Fire pumps are larger and have higher capacity. They are designed to deliver a much larger volume of water, typically in the range of hundreds to thousands of GPM.


Jockey Pump: Jockey pumps are usually electrically driven and automatically activate when the pressure in the fire protection system drops below a certain level.

Fire Pump: Fire pumps can be electrically or diesel engine-driven. They are typically activated automatically when a pressure drop is detected in the fire protection system, or they can be manually activated.

Code Requirements:

Jockey Pump: Jockey pumps may not be required in all fire protection systems. Their use depends on the specific design and requirements of the system, as outlined in applicable fire protection codes and standards.

Fire Pump: Fire pumps are typically required in larger fire protection systems, such as high-rise buildings or structures with significant fire protection needs. Their installation and performance are regulated by specific fire protection codes and standards.

It's important to consult with fire protection professionals and refer to relevant codes and standards to determine the appropriate type and specifications of pumps needed for a specific fire protection system.
