Fire pumps are essential components of a building's fire protection system, especially in high-rise structures. In buildings with levels from 400-500 ft. and higher, fire pumps are critical in distributing water through sprinkler systems where water pressure from water mains and fire fighting equipment cannot reach.

Even in lower set buildings, a fire pump is key to containing a fire. Firefighting, at its best, is a hazardous business, but without a well-designed and professionally installed system and pump it becomes even more dangerous, and business assets and lives are put at greater risk.
How Does a Fire Pump Work?
A fire pump is an integral part of a fire sprinkler system, as it provides high-pressure water accessibility to the fire sprinkler system, increasing the flow rate of the water.
To understand how a fire pump works, it’s important to understand what a fire pump is. A fire pump is more than just it’s namesake - a pump - which is an integral part of the system, but the full system is made up of the motor - or driver - and the controller. As part of a fire sprinkler system, a fire pump receives water from either an underground water supply or a water tank, lake, or reservoir, and is powered by electricity or diesel fuel. The high-pressure supplied by the pump distributes water through the sprinkler system and hose standpipes.
Customary types of fire pumps include the horizontal split case, vertical split case, vertical in-line, and vertical turbine.
The most common type of fire pump is the horizontal split case. These pumps are most economical for higher flow applications and are easily accessible for repairs or maintenance. Their long lifespans and size availability make them even more popular.
Vertical split case fire pumps are very similar to horizontal split case fire pumps except that they take up less space due to their vertical design, which also protects the pump from potential flooding damage.
The vertical in-line pump is a single-stage centrifugal pump designed, as the name implies, for vertical installation. With suction and delivery inline with each other, this pump provides a smooth flow of water throughout the system, and is ideal for small spaces. The design does require the pump to be removed for any repairs or maintenance.

The vertical turbine is a centrifugal pump designed for fire pump services where the water source is located below ground. This fire pump comes in varying types such as oil-lubricated enclosed-line-shaft and water-lubricated open-line-shaft pumps. Both types are designed for installation in drilled wells, lakes, streams, open swamps, and other subsurface sources. Report this page
