Fire pumps are an essential part of many facilities’ fire protection features. Whether they draw water from a stationary source, or boost the pressure from a tank or municipal supply, they should be protected in such a way that they will operate under the worst conditions.
NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection requires that the fire pump, driver, controller, water supply, and power supply be protected against possible interruption of service through damage caused by explosion, fire, flood, earthquake, rodents, insects, windstorm, freezing, vandalism, and other adverse conditions.
Indoor fire pumps in highrise buildings must be physically separated from the building or protected by 2-hour fire-resistance-rated construction. Indoor fire pumps in non-highrise buildings must be physically separated or protected by fire-resistance-rated construction in accordance with this table.
Fire pump units located outdoors shall be located at least 50 ft (15.3 m) away from any exposing building and also are required to be provided with protection against possible interruption. For additional information, refer to NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection.
