What Is An Emergency Fire Pump?

Emergency fire pump is an emergency fire pump with independent power source, which can start quickly and has self-priming ability. It is mainly used to fire the engine room through the emergency fire pump when the main fire pump cannot be started when the engine room area is on fire.

Fire pump has a variety of classification methods, according to the use can be divided into spray pump, hydrant pump, pressure pump, etc., these fire pumps from the structure is much the same, but according to the actual use of different head and flow.

Spray pump: It is a fixed device in the fire sprinkler system, which is widely used at present, with low price, long life and high fire extinguishing efficiency. The fire sprinkler system can also work synchronously with other fire fighting facilities, which can effectively control and extinguish the initial fire.

Hydrant pump: hydrant pump is divided into vertical single-stage, vertical multi-stage, horizontal multi-stage, horizontal single-stage and other structural forms, mainly used for hydrant system pressurization water supply. The flow range of the liquid is generally 5 ~ 80L/s, the pressure range is 0.2 ~ 2.25MPa, the supporting power range is 1.5 ~ 200kW, and the diameter range is 50 ~ 250mm.

Pressure regulator pump: the pressure regulator pump flow is small, usually from the fire pool or high fire water tank to the system to maintain the pressure in the system pipeline, in the event of a fire, to provide the flow for starting the system until the main fire pump starts, the pressure regulator pump needs to set up a backup pump.

In addition, it can be classified according to different ways of use: fire pumps for water supply, fire pumps for pressure regulation and fire pumps for foam use; Classification according to operation mode: diesel fire pump, electric fire pump; Classification according to structure: vertical fire pump, horizontal fire pump; According to the material classification: cast iron fire pump, stainless steel fire pump; According to different outlet pressure levels: low pressure, medium pressure, high pressure and other types of fire pumps. There are diving special fire pump, deep well special fire pump and ordinary type of fire pump.
