![]() ![]() While a generator set and fire pump system might use similar diesel engines, their design and installation in certain vital areas are drastically different.įor all fire pump applications, diesel engines must be “listed” for the fire pump system application. A diesel engine driver is commonplace for larger generator sets. Diesel engines have been used in light- and heavy-duty applications for decades. This column will discuss design and installation issues with a diesel engine-driven fire pump system. They also are used by clients who desire a primary electric motor-driven fire pump system and a redundant diesel engine-driven fire pump system or used in a property requiring a redundant system due to its seismic zone or height. Diesel engines are often used when the electrical supply to the property is unreliable or has insufficient capacity. While electric motors are most common, steam drives are infrequently utilized. The current version of the standard is the 2019 edition, with updates occurring every three years.Ī fire pump can be driven by an electric motor, diesel engine or steam drive. The National Fire Protection Association developed NFPA 20, Standard for the Installation of Stationary Fire Pumps for Fire Protection, covering the design and installation of fire pump systems. Using a fire pump system may allow a property to be developed where sufficient water pressure is not available. The installation of a fire pump system in a commercial or industrial property is a common occurrence. ![]()
