The fire pump is the heart of your sprinkler system. It is the sole component responsible for supplying the water pressure needed when a sprinkler head demands it. Because municipal water pressure varies from location to location, fire pumps are customized for each specific site. Your fire pump is, by far, the most expensive component in your fire sprinkler system. These are some of the reasons why it’s important to have an experienced and knowledgeable technician maintain and service your fire pump.

At FirePro we’ve installed, maintained, and repaired fire pumps for the past many years. In fact, we have specialized employees dedicated to working on fire pumps only. The cost and importance of your fire pump demands this level of expertise.

How do fire pumps work?

Fire pumps are powered by an electric motor or diesel engine. If the local building code requires power independent of the local electric power grid, a pump using an electric motor may utilize what’s called a transfer switch that directs power over to an emergency generator in the event of a power failure.
The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are activated or alternatively when other firefighting connections are opened, causing a pressure drop.
Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.

A jockey pump is a small pump connected to a fire sprinkler system in parallel with the fire pump. It maintains pressure in a fire protection piping system to an artificially high level so that the operation of a single fire sprinkler will cause an appreciable pressure drop which will be easily sensed by the fire pump automatic controller, causing the fire pump to start. The jockey pump is essentially a portion of the fire pump’s control system.
Fire pump installations and retrofits are governed by the National Fire Protection Association’s (NFPA) NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.
