Tips about fire pumps

With the continuous progress of the times, the application of diesel engine fire pumps is becoming more and more extensive. Diesel engine fire pump is a common necessary facility. Only when the fire signal comes, and the electric water pump fails or the power supply is cut off, the diesel engine fire pump will automatically start. The diesel engine fire pump is installed together with the electrical instrument, with complete functions, compact structure, automatic fault alarm, accepting the starting signal, and can automatically complete the starting procedure and run at full load quickly. When the diesel engine fire pump is insufficient in fuel, low battery voltage, and high lubricating oil temperature , enough to ensure that the diesel engine fire pump starts in a low temperature environment, the entire system of the diesel engine fire pump is safe, reliable, and easy to use.

ZJBetter provide three types of fire pump system, such as diesel engine fire pump set, electric driven fire pump set, EDJ fire pump set.

The diesel fire pump set is easy to maintain, has a high degree of automation, reliable performance, and a wide range of equipment pressure and flow. XBC type automatic diesel engine fire pump set, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in fire water supply under unexpected circumstances such as no power supply or abnormal power supply (mains power).

Firefighting pumps are critical assets in disaster response and emergency management scenarios, where rapid and effective fire suppression is essential for protecting lives and property. These pumps can be deployed in various emergency situations, including natural disasters like wildfires, earthquakes, and floods, as well as human-made disasters such as industrial accidents or terrorist attacks.

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.

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.

All accessories of ED small fire-fighting complete water supply equipment are assembled according to the standard (NFPA20). Its configuration depends on the customer’s needs, or the number of pumps and the type of electric and diesel pumps. ED small fire pump sets are usually equipped with two pumps, a main pump (electric centrifugal pump) and a backup pump (diesel centrifugal pump). The choice of electric motor and diesel engine depends on the reliability level of the system.

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

1. Visually inspect the fire pump for any signs of damage or leaks.

2. Check the oil level and add oil as necessary.

3. Check the suction and discharge valves for proper operation.

EDJ series fire pump set consists of electric pump + diesel pump + jockey pump and all accessories.
The pump model of the electric pump and the diesel engine pump are all OTS split case pumps, and the jockey pump is a CDL pump. The three pumps are automatically switched, and can work even if the power is cut off. It adopts high-quality bearings and wear-resistant packing seals.

The fire pump is part of the water supply of the fire sprinkler system and can be powered by electricity or diesel. The inlet of the pump is connected either to a public groundwater supply or to a static water source (e.g. tank, reservoir, lake). The pump supplies water at higher pressure to the sprinkler system risers and hose risers.
Fire pumps generally use three driving forces, including diesel engines, gasoline engines and electric motors. Gasoline engines are commonly used in portable fire pumps and light duty firefighting. Electric motors are the most widely used driving force for fire pumps and are both efficient and convenient.

The video displays detailed analysis of fire pump set test. Fire pump sets manufactured by our factory are tested before delivery.

A typical firefighting pump system consists of the pump itself, intake and discharge hoses, nozzles, strainers or filters to prevent debris from entering the pump, and sometimes additional accessories like foam injection systems for enhanced fire suppression capabilities.

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.

Sizing diesel fire pumps involves evaluating factors such as the building’s occupancy classification, area of coverage, hazard level, and required flow rates for firefighting purposes. Hydraulic calculations are typically performed to determine the water demand and pressure requirements, which are then used to select a diesel fire pump with the appropriate capacity and performance characteristics. It’s essential to work with qualified engineers or fire protection specialists to ensure that the pump is sized correctly for the specific application.

Fire pumps are an important part of the fire protection system, especially in high rise structures.In basic 400 – 500 or advanced water situations, fire pumps are important to distribute water into water lines and sprinkler systems where the water pressure of the fire fighting equipment cannot reach. Especially in low-rise structures, fire pumps are important for fire control.
Stylistically, fire protection is a dangerous activity, but without a well-designed and professionally installed system and pump, it certainly becomes more dangerous and commercial assets and lives are less at risk.

The ED Dual-Power Fire Pump System combines electric and diesel engine pumps to ensure uninterrupted fire protection and a reliable water supply. In the event of power outages or electrical failures, the diesel engine pump seamlessly takes over, guaranteeing continuous operation of the fire protection system.

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.

Fire pump equipment has the characteristics of mature technology, high degree of automation, protection function, reasonable structure and easy installation. At the same time, in order to meet the different needs of users and reasonable investment, the products are divided into fire pump, industrial emergency pump, agricultural pump and other application series, can be linked with the electric fire pump switch use.
