Fire Pumps, An Indispensable Component Of A Fire Protection System

If a sprinkler system is to work properly, protecting the building around the clock; a fire pump of the correct size is a critically important component. Depending on the size of the building, Peerless fire pumps in Houston, TX must be chosen correctly, they must provide a certain pressure and a certain flow measured in gallons per minute.

Many large buildings cannot rely on the pressure and flow of the municipal water system to meet the design demand of the sprinkler system and standpipes. Under these conditions, fire pumps are required to boost the pressure.

Determining the pressure requirement of the fire pump:

The regulating agency in the United States is the NFPA, National Fire Protection Association. Sizing a fire pump is done in accordance with codes established by this agency. In the case of properly sizing a pump, there are two acceptable methods used by fire protection engineers; standpipe method and sprinkler area method.

  • Standpipe method: This method is considerably less complicated and is acceptable for smaller buildings that need protection. The calculations are based on the quantity of standpipes in the building. The maximum pressure is 1000gpm.

  • Sprinkler area method: This method of calculating the size of fire pumps is more complex but is far more accurate when designing a system for a large building. Before the pump can be sized the first step is defining the hazard level. The levels span from light to extra hazard. Typically a hospital would be considered light hazard while a plastics processing plant for example would be considered extra hazardous.

There are different designs of Peerless fire pumps in Houston, TX. The most common is a double suction design typically rated up to 5000gpm. Inline pump designs are more compact and are ideal for many installations.
