NFPA 20 requires fire pumps to be powered by a continuously available power source, usually identified as an uninterruptible power source. In many cases, this requirement requires a backup generator to be provided as a backup power source in the event of a power failure, in which case the fire pump controller must be equipped with an automatic transfer switch. The choice of fire pump depends on the building infrastructure and available space. The most common choices for fire pump drives are electric motors and diesel engines.

All places need to be equipped with fire-fighting facilities, and fire pumps are the water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps require power systems. supply. In case of power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Fire sprinkler systems are hydraulically calculated prior to installation to determine adequate water flow and in order to ensure the system can reliably suppress a fire until fire crews arrive. When it’s determined inadequate flow is available from a municipal supply for the system to operate effectively, a fire pump is installed. The fire pump operates when the sprinkler system pressure drops below a certain threshold, due to the operation of sprinkler heads. The fire pump draws additional water from the municipal water supply or on site storage tanks, to maintain the sprinkler systems required operating pressure. Fire pumps are often required in high rise construction and large area buildings, due to the size of piping systems and pressure loss.
