How to Choose an ED Fire Pump Set

Prior to installation, fire sprinkler systems are hydraulically calculated to ensure adequate water flow and that the system can reliably suppress a fire until fire crews arrive. When it is determined that there is insufficient flow from a municipal supply for the system to function properly, a fire pump is installed. The fire pump activates when the sprinkler system pressure falls below a certain threshold as a result of sprinkler head operation. To maintain the required operating pressure of the sprinkler system, the fire pump draws additional water from the municipal water supply or on-site storage tanks. Due to the size of piping systems and pressure loss, fire pumps are frequently required in high rise construction and large area buildings.

EDJ series fire pump set consists of electric pump + diesel pump + Jockey pump and all accessories.
The pressure switch and the control cabinet can automatically turn on/off the three pumps – the electric pump and the pipe charging pump work when there is electricity, and the diesel pump when the power is off.

The DJ Fire Pump Set is a combination system consisting of a diesel engine pump and a jockey pump, designed for fire safety in the construction and industrial sectors.

In cold climates or areas prone to extreme weather, fire pumps face unique operational challenges that require careful design and maintenance. Freezing temperatures can cause water to freeze in the pipes, potentially damaging the fire pump and other components of the fire suppression system. To mitigate this, fire pumps may be installed in heated enclosures, and antifreeze solutions or dry-pipe systems are often used to prevent freezing. Jockey pumps help maintain system pressure, but in extreme weather, they must be monitored closely to ensure they don’t overcompensate for changes in pressure caused by temperature fluctuations. High winds, flooding, or snow accumulation can also impact the performance of fire pumps, especially in outdoor or exposed installations. Ensuring that fire pumps have robust weather protection, backup power supplies, and regular winterization procedures is critical for maintaining their reliability in harsh conditions. Additionally, these pumps should be designed with durable, weather-resistant materials to withstand long-term exposure to extreme environmental factors while still delivering dependable fire protection.

Fire pumps have a wide range of uses. In addition to providing water for fire-fighting piping systems, they can also be used for industrial water delivery. Fire pumps can also be used for water supply and drainage systems in cities. There are also other relatively long-distance water delivery tasks, such as heating boilers, hot and cold water circulation pressurization of bathroom boilers and multi-stage fire pump furnaces, etc., can all be completed by means of fire pump systems.

The engine cooling system of the diesel engine fire pump adopts double closed-loop heat exchangers. The system has the advantages of high cooling efficiency and little impact on the ambient temperature of the pump room. The cooling water flow direction is controlled by a ball valve from the pump outlet pipe to the heat exchanger, so that the cooling water temperature of the machine body is between 85 and 95 °C. If the water temperature is too high, you can increase the opening of the ball valve, increase the heat dissipation capacity of the heat exchanger, and reduce the temperature of the engine cooling water.

Yes, there are regulations and standards set by local, state, and national authorities that dictate the installation, testing, and maintenance of fire pumps. Compliance with these regulations is essential for ensuring the effectiveness of fire protection systems.

The fire pump refers to a clean water pump used for fire water supply, and a single pump that handles medium temperature below 80 degrees and is not corrosive. The pump set is the joint operation of multiple fire pumps to ensure the quantity and stability of the water supply. The electric motor fire pump group adopts multiple fire 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 main components of the electric motor fire pump group are the motor and the pump body. The subdivision of the pump body is the pump casing, the impeller, the pump shaft, the bearing, the coupling, the sealing form, the lifting pipe, etc. The specific fire pump model is determined according to the environment and performance requirements. According to the material quotation required by the customer, accurate selection is beneficial to on-site use and reduces failure problems.

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 diesel engine pump set has the characteristics of good startability, strong overload capacity, compact structure, convenient maintenance, simple use and high degree of automation. It is a kind of fire fighting equipment with reliable performance.

Mutistage EEJ Fire Pump Set comprises a combination of two sets electric motor driven pump and jockey pumps that supply for fire suppression systems.

1. Ability to provide a steady and reliable flow of water: Fire pumps are designed to provide a steady and reliable flow of water to the fire suppression system. This ensures that the fire is extinguished quickly and without any damage to the property.

2. High-Pressure Output: Fire pumps can provide a high-pressure output to ensure that the water is able to reach further distances and at higher pressures than would be achievable by a standard water system. This is important in controlling and extinguishing fires, as it allows the water to reach all areas of the fire.

3. Emergency Operation: Fire pumps are designed to be able to operate in the event of a power outage. This ensures that the fire suppression system can still be operational in the event of a power failure. This is especially important in commercial buildings and other areas where power outages can occur.

4. Automatic Activation: Fire pumps are designed to automatically activate in the event of a fire. This ensures that the fire suppression system can be activated quickly and without any manual intervention. This is especially important in the event of a large fire, as it ensures that the system is already in operation before the fire department arrives.

5. Low Maintenance: Fire pumps are designed to be low maintenance, requiring only regular inspections and maintenance to ensure that they are working correctly. This ensures that the fire suppression system is always ready for use and that it can be relied upon in the event of a fire.
