When the water supply doesn’t have enough pressure, a fire pump can be an excellent solution to the problem, as long as the pump is sized correctly. The fire pump is selected by five factors: liquid delivery volume, device lift, liquid properties, pipeline layout and operating conditions.

The EDJ fire pump unit consists of a fire pump, a double-shaft motor and a diesel engine. One end of the output shaft of the double-shaft motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the double-shaft motor is connected to the One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through an action drive circuit. With dual-power fire pumps, there is no need to configure a second fire pump, which reduces floor space and saves manufacturing costs.

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. This system utilizes the powerful power output of the diesel engine pump, ensuring reliable operation even in the event of a power outage.

Fire pumps are necessary because municipal water supplies might not always provide sufficient water pressure to effectively fight fires in large buildings or areas. Fire pumps boost the water pressure to ensure proper coverage and firefighting capabilities.

Minor repairs can often be made to fire pumps, but major issues may require replacement or extensive refurbishment. It’s important to consult with experts in fire pump maintenance for guidance.

As a fixed fire-fighting equipment, the diesel engine fire-fighting pump set has been widely used in fire-fighting diversion, especially for fire-fighting water supply in unexpected situations such as no power supply or abnormal power supply (mains power). The fire pump equipped in the unit is a horizontal single-stage and multi-stage fire-fighting special pump. It is mainly composed of diesel engine, fire pump, connection device, fuel tank, radiator, battery pack, intelligent automatic control panel, etc.

Fire pumps can be installed in locations with limited space, but it’s important to follow space requirements outlined in the manufacturer’s specifications and local codes. Proper clearances around the pump ensure ventilation and accessibility for maintenance.

Diesel engine fire pumps are large-scale fire pumps. Diesel engine fire pumps are currently the hottest fire pumps on the market, especially in large warehouses, docks, airports, petrochemicals, power plants, and liquefied gas stations. This kind of fire pump with large flow and high power is often needed.

In order to match the service cycle of the fire pump, the inspection of the diesel engine and the fire pump should be regularly checked, and the parts to be replaced or repaired should be adjusted and corrected in a timely manner. We need to check the fuel tank reserves and oil quality of the diesel engine fire pump every day; the usage of the battery; the cooling system, etc., the pump shaft, impeller, bearing, and the wear of the water pipe and filter screen of the water pump. (Diesel engines of different brands may be different, and should be checked and maintained according to the specific model and structure of the diesel engine).

The motor of this fire pump set is directly connected to the fire pump, which simplifies the intermediate transmission structure and enhances the stability of operation. The equipment occupies a small area, saves costs, and is a cost-effective fire pump set.

A multistage pump refers to a pump with two or more impellers, which can absorb and press water in stages and multiple stages, so as to lift the water to a high position, and the lift can be increased or decreased according to the needs of the pump impeller. The multistage pump can be equipped with a four-stage motor by increasing the number of impellers when the single-stage pump head needs to be equipped with a two-stage motor, which can improve the service life of the pump and reduce the noise of the unit. It is placed flat on the ground, with better stability, large flow and head, and wider application.

Diesel engine fire pump is a kind of mechatronics equipment that is directly driven by diesel engine fire pump and can start and complete water supply in a short time. Diesel engine pump set is driven by diesel, no external power supply is required. Diesel engine pump is suitable for agricultural irrigation, emergency rescue, smelting, hangar, petrochemical oil depot, power plant, liquefied gas station, textile and other fire-fighting water supply occasions, especially in the absence of electricity, When the power grid is not satisfied, it is the safest choice to use a diesel engine to drive the water pump.

A fire pump is a critical component of a fire protection system. It is designed to increase the pressure and flow of water to ensure an adequate water supply for firefighting.

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. This system utilizes the powerful power output of the diesel engine pump, ensuring reliable operation even in the event of a power outage. The jockey pump maintains a constant water pressure, optimizing the performance of the fire suppression system. The DJ Fire Pump Set offers a reliable and efficient solution for prompt response to fire incidents, making it an essential component for protecting property and ensuring occupant safety.

Fire sprinkler systems are hydraulically calculated prior to installation to determine adequate water flow and in order to ensure the system can reliably suppress a fire until fire crews arrive. When it’s determined inadequate flow is available from a municipal supply for the system to operate effectively, a fire pump is installed. The fire pump operates when the sprinkler system pressure drops below a certain threshold, due to the operation of sprinkler heads. The fire pump draws additional water from the municipal water supply or on site storage tanks, to maintain the sprinkler systems required operating pressure. Fire pumps are often required in high rise construction and large area buildings, due to the size of piping systems and pressure loss.

Maintenance records provide a documented history of the pump’s condition, service intervals, and repairs, which are vital for compliance, insurance, and ensuring that pumps are in good working order during emergencies. Regular records also help identify recurring issues, allowing for proactive maintenance.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, it can also be equipped with other diesel engines as power machines according to the needs of users.
