The 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.

The Chiller pump is used. As the pump is located remote from the engine room space, it can be used as a backup for the main fire pump. The chiller cools the system and moves the heat away from the equipment and product. The cooled liquid absorbs heat from the equipment, warming it. Warmed liquid is pumped back to the chiller to be cooled again.
