Product Introduction of EDJ Fire Pump System

Electric fire pumps are used in various water environments, not only to meet the general water supply but also to be a good helper for fire-fighting water. The electric 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 electric fire pump is aimed at various fire water environments, so the selection should also be based on the actual demand environment, performance parameters, etc.

As usual, Fire pump system include Diesel engine pump + Electric motor pump+Jockey pump. Sometime, it just include Electric pump+Jockey pump.
Its power: 1.0 to 20kw, flow: 15-300gpm, head: 3-10bar, 50/60hz. The material: Cast iron or SS, bronze impeller.

– Rapid Evacuation: Ensuring the system supports rapid evacuation procedures to minimize risk to large crowds.
– Flexible Design: Providing flexible design options to accommodate varying event setups and capacities.
– Noise and Disruption Minimization: Ensuring minimal noise and disruption to maintain a pleasant environment.
– Compliance with Event Space Standards: Adhering to fire safety regulations and standards specific to high-occupancy event spaces.

Diesel engine fire pumps are suitable for use in fire water supply environments with high head and high flow rate or as backup fire water supply pumps. The reason is that the diesel engine has strong power and can be used with large flow fire deep well pumps, and the diesel engine fire pumps have the characteristics of self-starting when power is off. Emergency water supply is available, so diesel engine fire pumps are favored.

Electric fire pump: It is an important part of the fire water supply system. Divided into ordinary type and foam type. The ordinary type is used for general fire water supply; the foam type is equipped with an adjustable proportion mixer and a cam pump, which can deliver the mixed liquid to various foam launching devices to extinguish various oil fires. The electric fire pump consists of two parts, the motor and the pump. The pump and the motor are coaxial. The pump structure includes pump body, rotor, pump cover, mechanical seal and other components.

At higher altitudes, the atmospheric pressure is lower, which can reduce the performance of fire pumps. To compensate for this, fire pumps may need to be oversized or specially configured to deliver the necessary pressure and flow in high-altitude environments. Proper planning and design are essential to ensure that the system functions effectively under these conditions.

A fire pump is a device that increases water pressure for fire protection systems, while a fire hydrant is an external water supply point for firefighters to connect hoses. Fire pumps are often used within buildings, while fire hydrants are located externally for access by firefighting teams.

EDJ series fire pump set consists of electric pump + diesel pump + jockey pump and all accessories.

The diesel engine fire pump has the characteristics of good starting performance, serious load operation, compact structure, time-saving and labor-saving maintenance, simple application, and high level of automatic control technology. It is a security monitoring device with reliable performance. The full name of the diesel engine fire pump we usually say is the engineering diesel fire pump set, which can operate at an ambient temperature of -25~55°C, and can be automatically charged, automatically started, and has the functions of automatic alarm and automatic preheating. It is very reliable.

The equipment is suitable for fire water supply and emergency water supply in various occasions such as warehouses, docks, airports, petroleum, chemical, factories, power plants, liquefied gas, textiles, ships, cruise ships, etc.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the jockey pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

The diesel engine fire pump unit is directly driven by the diesel engine fire pump, and it is a mechatronic equipment that can start and complete the water supply in a short time. The diesel engine pump set is driven by a diesel engine without external power supply. Diesel pumps are suitable for fire water supply occasions such as agricultural irrigation, emergency rescue, smelting, hangars, petrochemical oil depots, power plants, liquefied gas stations, and textiles. Especially in the case of no electricity and dissatisfaction with the grid, choosing a diesel engine-driven water pump is the safest choice.

1. Disconnect the power and turn off the fuel source.

2. Remove any remaining fuel in the pump.

3. Clean the pump with a mild detergent and warm water.

4. Flush the pump with clean water.

5. Grease the bearings and any moving parts of the pump.

6. Reassemble the pump.

7. Reconnect the power and fuel source.

8. Test the pump to ensure it is functioning properly.

The diesel engine fire pump set has good starting performance, compact structure, humanized design, convenient maintenance, simple and convenient use, and high degree of automation. It is a very good fire pump. The diesel engine fire pump has the advantages of long head and wide application range, and can meet the fire water supply in multiple places such as warehouses, docks, airports, power plants, liquefied gas stations, and petrochemical industries.

Fire pumps are part of the water supply to a fire sprinkler system and are powered by electricity, diesel or steam. The pump inlet is either connected to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). This pump provides higher pressure water flow to sprinkler system risers and hose risers. Our company can manufacture fire pumps that meet NFPA20 standards.

With the characteristics of full sealing, no leakage and corrosion resistance, fire pumps are widely used in environmental protection, water treatment, fire protection and other departments. They are ideal pumps for building non-leakage, non-pollution civilized workshops and civilized factories. Our 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. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Fire pumps are designed to run continuously during a fire emergency. They must be able to sustain operation for the duration required to control or extinguish the fire, which can be several hours.

While the primary purpose of fire pumps is firefighting, some systems may incorporate them for other water supply needs, such as industrial processes or water distribution. However, their design and functionality are optimized for firefighting applications.
