Figuratively speaking, a fire water pump is the “heart” of the fire hydrant system, automatic sprinkler system and other water extinguishing system. If the fire pump can not start in the fire fighting, the fire cannot be put out. Therefore, the fire water pump must work continuously during the whole fire fighting process to provide a sufficient flow of water to extinguish the fire. The fire water pump diesel engine plays an irreplaceable role, but firefighting supervisors have found in the acceptance, supervision and inspection of construction projects that some owners, constructors and maintenance managers fail to attach great importance to the model selection and setting of fire pumps, resulting in the building fire extinguishing system with “congenital heart disease”.

Do you know how to select the right fire pump model? Here some factors to be considered are listed below.

When selecting a fire water pump diesel engine, you should mainly consider the water flow and delivery head required by the fire extinguishing system in the fire state. The following aspects should also be considered if the water flow and delivery head meet the specified requirements.

1. Choose a centrifugal pump. General buildings have fire water with a wide range of delivery head and water flow. A centrifugal pump has wide working area, and there are many product varieties, series and specifications available on the market, which helps you choose and maintain. In addition, the centrifugal fire water pump diesel engine can operate stably under closed gate for a short time (2~3min).

2. Select a water pump with high efficiency to meet the required water flow and delivery head to protect the entire fire extinguishing system of the building.

3. Backup pumps should be installed to ensure the reliable water supply. The backup pump and the working pump should be ready to be started at any time, and its working capacity should not be smaller than that of the large working pump, so that the fire water pump diesel engine can provide uninterrupted supply of water in case of fire.

4. Consider diesel engine fire pump settings when selecting the model. The arrangement of pump units should be based on the principle of safe pump operation and convenient management.

5. Automatic feed water device should be used to ensure that the fire pump can quickly start. Reliable and rapid water feed water equipment should be available if it’s hard to achieve automatic feed water.
