Fire Pumps and Systems: The Most Commonly Asked Questions


At its best, firefighting is a hazardous business. And without a well-designed fire protection system and a fire booster pump, it becomes even more dangerous to save assets and lives. A fire pump is an important part of your sprinkler system and is essential in buildings with levels higher than 400-500 ft.

Especially in high-rise structures, fire pumps and systems are critical in distributing water through sprinklers. This is true where water pressure from water mains can’t reach the sprinkler system. It usually happens when the fire pump intake is either connected to the public water supply or a static water source like a tank, reservoir, lake, etc.

·         What does a Fire Booster Pump do?

The role of the fire pump is to provide water flow to the sprinkler risers and hose standpipes at a higher flow. It starts when the water pressure in the fire protection system drops below a certain threshold.

The fire pump is powered either by an electric motor or a diesel engine. If a building code requires power that is free from the local electric power grid, you will need an electric motor connected via a listed transfer switch and the installation of an emergency generator.

·         When do You Need a Fire Pump?

To determine whether you need a fire booster pump, compare the fire suppression system demands with the available water supply. If the supply cannot meet the demands, you will need a fire pump. Conversely, if the water supply meets the pressure demands, you don’t need a fire pump.

·         What are the Standards Governing Fire Pumps?

Code-compliant fire pumps and systems for commercial and industrial buildings begin with the standards governing fire pumps. According to the US-based National Fire Protection Association - NFPA, the standard for installing stationary pumps is the most widely accepted standard. NFPA 20 is considered the leading code, with its many safety measures that are designed to account for all conceivable scenarios and ensure maximum fire protection.

NFPA 20 addresses everything from the fire pump room to the water source itself. The standard provides installers, designers, and manufacturers with minimum requirements for the design, manufacture, installation, and testing. It ensures that each of the individual components would perform as a whole when the system is active.

·         How Often Should You Inspect/Test Your Fire Pump?

It is likely that your building contains a sprinkler system and a fire booster pump as part of your fire protection equipment. These are automatic systems that act as the first line of defense when a fire breaks out. A vital part of your fire safety plan is to inspect your fire pump so that it can perform optimally. You may wonder how often you should inspect and test your fire pump. Well, this can be done regularly, weekly, monthly, and yearly.

·         Why You Should Install a Jockey Pump in the Fire System

Fire pumps and sprinkler systems are designed to put out fires as quickly as possible. This is done by a set of sprinklers connected to each other and to the water source. When the sprinkler system is active, it will take only a few seconds for the sprinkler to release water.

However, there is a need to maintain pressure in the pipes, so each fire sprinkler loses a small amount of pressure when it turns on. When a fire breaks out and a sprinkler turns on, there must be enough pressure in the pipes to activate the next sprinkler.

Here, installing a jockey pump could save your day. It is designed for this purpose and will turn on whenever it senses a certain amount of pressure drop in the fire protection system. It will maintain water pressure to help the fire booster pump operate without any delay.

The Bottom Line

Without a fire booster pump, your fire sprinkler system will only work until there is a prolonged water supply and pressure. This means that the system won’t be able to reach every corner of your building and put out an entire fire by itself. So, rest easy knowing that having a sensing line for fire pumps would help you ensure fire safety 24/7.
