3. Control panel: Automatically control the water pump with overload and overcurrent protection.
4. Accessories: suction pipe, discharge pipe with flange, battery, gate valve, check valve, flexible expansion joint, pressure switch, pressure gauge, base, etc

Electric fire pumps are pumps used to pump clean water and liquids with physical and chemical properties similar to water. They are mainly used in factories, mines, urban water supply, air conditioning systems, fire protection systems and agricultural irrigation. For pumps of the same specification, changing the outer diameter of the impeller can have different performance. The pump has simple structure, reliable performance, small volume, high suction lift, low energy consumption and easy maintenance.

DJ Fire pump set Fire pump set consists of one pump coupled to diesel engine, jockey pump, pressure vessel, controller for manual or automatic operation of system and standard accessories mounted on base frame.And this fire pump system can be customized for different purposes such as high rise buildings, facilities,hospitals, supermarkets,shopping malls,villas,apartments,etc.

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.

The fire pump is actually a pump that needs to be used in fire protection. According to different classification methods, it can be divided into different types of pumps. With its characteristics of full sealing, no leakage and corrosion resistance, it is widely used in environmental protection, water treatment, fire protection and other departments to pump various liquids. The pump types of the system are similar, but the head and flow are different. The selection basis of the fire pump should be considered from five aspects according to the technological process and water supply and drainage requirements. Fire truck fire pumps are used in fire protection, water treatment, environmental protection and other departments to pump various liquids.

The EDJ fire pump set is tested in the Better factory, and our company’s fire pump set needs to be tested after the assembly is completed to ensure the quality. EDJ fire pump sets are widely used in large public places, factories, firefighting and other occasions.

Yes, there are various types of nozzles available for firefighting pumps, each designed for specific purposes. For example, fog nozzles disperse water into a fine mist, which is useful for cooling and controlling fire, while solid stream nozzles deliver a concentrated stream of water for long-range firefighting. Choosing the appropriate nozzle can significantly impact the effectiveness of firefighting efforts.

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.

In some cases, existing buildings may need to retrofit or upgrade their fire pump systems to comply with updated building codes or address changes in occupancy. Consulting with a fire protection professional is crucial to ensure proper modifications.

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.

The dual-power fire pump is driven by a diesel engine. When the power grid cannot meet the requirements, the diesel engine can be used to drive the water pump to ensure that the unit can reach the running state.
