All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original electric fire pump.

Fire pump package comprises a combination of electric motor driven pump, diesel engine driven and electric motor driven jockey pumps that supply for fire suppression systems.

The electric motor fire pump is an important water supply equipment in the fire protection system. The electric motor fire pump has a wide range of head, flow and power, and can be used in many environments. Providing sufficient water supply is the key to ensure emergency use.

Yes, installing diesel fire pumps in different environments or applications may require special considerations to address factors such as ambient temperature, altitude, seismic activity, corrosive atmospheres, and specific regulatory requirements. For example, pumps installed in outdoor or exposed locations may require weatherproof enclosures or additional corrosion protection, while pumps installed in seismic zones may need to be anchored securely to withstand earthquakes.

Flow testing is a critical aspect of fire pump maintenance and compliance with safety standards. This article explores the fundamentals of fire pump flow testing, including procedures, equipment, and the significance of accurate testing to verify system performance. It discusses the relationship between flow testing and water distribution and highlights the need for regular testing to ensure optimal fire protection.

The size of a fire pump is determined through hydraulic calculations based on the specific fire protection requirements of the building. Factors considered include the building’s height, area, occupancy type, and the required flow rate and pressure to meet fire protection standards.

EDJ fire pump set is composed of electric pump, diesel pump and stabilized pressure pump. In daily use, as an auxiliary pump, the stabilized pressure pump keeps the existence of liquid (water) in the fire pipeline at all times, and the electric pump works as the main power pump in normal work. When the circuit system is burnt out due to a serious fire, the diesel pump will start instead of the electric pump within ten seconds, which will not be affected by the circuit and complete the fire fighting work. In recent years, EDJ fire pump group has gradually become the first choice of fire protection systems in various office buildings and residential buildings, and its safety

Fire pumps are part of the applied water supply and are powered by electricity, diesel. They activate when the pressure in the fire sprinkler system drops below a certain level and provide a flow of water to the sprinkler system at very high pressure, which is then discharged onto the fire.

For supplying water to automatic fire fighting systems and installations with hydrants. Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity, diesel or steam. It is used to extinguish fires over a period of time.
The fire pump is equipped with a control panel where you can adjust the flow of water and its power.
It is the most important part of fire protection system safety, in order to ensure the safety of people inside buildings, schools, ministries, hospitals, markets, shops, factories, malls or any infrastructure, a fire pump system must be installed to prevent the fires they enter.
There are different types of fire pumps with different operations and capacities, for example; vertical and horizontal fire pumps powered by electric or diesel.

EDJ fire pump set is composed of electric pump + diesel pump + jockey pump. The pump set adopts ISO pump,ISO series centrifugal pump is a single-stage single-suction centrifugal pump developed by China Better Technology Co., Ltd. with reference to international similar products using modern fluid mechanics to meet the international standard ISO9908 secondary energy efficiency standard.

Three start-up functions for diesel engines:
1. Manual start function: manual and automatic interlocking can be completed through the transfer switch, and the manual start function can be realized:

2. Automatic manual function: allow to start three times. If the startup fails for three times, it will issue a “startup failure alarm” and automatically exit the startup state. After a successful startup, the time from startup to rated load is 5-10-15S (depending on the unit capacity);

3. Emergency manual direct start function: When the automatic control device fails, the emergency manual direct start function can be realized.

The fire pump is the necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. The commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between the two is that the electric fire pump needs power system supply. The electric diesel engine fire pump can be started at any time to fill the position of the original electric fire pump.

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. Can also be used, the fire pump set is widely used in various emergency firefighting occasions.
