Fire pumps are important equipment in modern fire-fighting systems. In addition to the sprinkler pumps used in automatic sprinkler systems, fire hydrant pumps are also used in fire hydrant systems, which are widely used in public places. Different from the general use of pumps, fire hydrant pumps form its different characteristics and special requirements. The water supply for fire pumps is generally given directly to the fire-fighting equipment with a fire hydrant pump.

Fire pumps are mainly used to pressurise the system pipes after the fire has been extinguished. Typically, fire pumps are used in a wide range of applications, most notably in the firefighting industry, but also in water treatment, environmental protection and so on. Of these applications, the fire fighting industry is the most used. The fire fighting industry makes full use of the advantages of fire pumps, which is the advantage of fast pumping. Because most of the work in the fire fighting industry is in fire fighting, the fire fighting gas pump plays a significant role.
The design of fire pumps is divided into different types depending on the classification of the fire pump. The types of pump for different types of fire protection systems are similar, but the head and flow rate vary. Therefore, we need to determine the actual situation according to the use, generally we recommend the purchase of high pressure fire pumps for large occasions.
The fire pump room is determined by the amount of water used and the height of the building. At the same time, the selection of the type of fire pump should pay attention to the choice of a pump with a relatively gentle performance curve as far as possible to prevent overpressure when the fire-fighting equipment is initially opened.
In short, unlike domestic water pumps, fire pumps do not need to consider the changing laws of water use and need to choose pumps with different flow rates to adjust the water volume to achieve maximum economic efficiency. The head required to fill the water column is at least twenty metres, plus the horizontal height of the hydrant mouth from the hydrant pump, plus the head loss, and these factors must be taken into account.
The selection of fire pumps should be based on the process flow of the fire pump application project to select. Therefore, when we select the fire pump, we should consider five aspects such as the liquid delivery volume, the head of the device, the nature of the liquid, the pipeline arrangement and the operating and running conditions. In judging the quality of the product, we suggest carefully watching whether the fire pump has passed the national compulsory inspection, to see the compulsory inspection report of the latest year, which is issued by the Ministry of Public Security Fire Product Conformity Assessment Centre.
