OTS series EDJ fire pump set display

Fire pumps are an important part of the fire protection system, especially in high rise structures.In basic 400 – 500 or advanced water situations, fire pumps are important to distribute water into water lines and sprinkler systems where the water pressure of the fire fighting equipment cannot reach. Especially in low-rise structures, fire pumps are important for fire control.
Stylistically, fire protection is a dangerous activity, but without a well-designed and professionally installed system and pump, it certainly becomes more dangerous and commercial assets and lives are less at risk.

Fire pump refers to a clean water pump used for fire water supply, and a single water pump with a non-corrosive treatment medium temperature below 80°C. The pump unit is a joint operation of multiple fire pumps to ensure the quantity and stability of water supply. The electric motor fire pump set adopts multiple fire water pumps powered by electric motors. The general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption.

The full name of diesel engine fire pump is engineering diesel engine fire pump set, which can be automatically charged, automatically started, and has the functions of automatic alarm and automatic preheating. The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

This is a set of EDJ fire pump set, which consists of electric pump + diesel pump + jockey pump. The three pumps are automatically started and stopped. When the joceky pump detects that the electric pump cannot operate normally, the diesel engine pump will start automatically.

The electric motor fire pump is manufactured with good structure and workmanship. It has a wide range of performance, and is easy to use and operate for a long time. The motor fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

Single-stage fire pumps have only one impeller, and multistage fire pumps can have two or more impellers. Because the pump core in them is different, the structure is different. The impeller of the multi-stage pump is more than that of the single-stage pump, which can achieve a larger head at the same flow rate. The multi-stage pump is the sum of the single-stage pumps, and the head and outlet pressure can be made very high.
