Diesel engine fire pumps can form an automatic fire water supply system with electric pumps and jockey pumps. See the introduction of “Diesel Engine Control System” for its working process. The equipment can realize joint control with the fire center. The fire pump unit is combined with the fire pump through the high elastic coupling. The unit also includes diesel tank, cooling water tank, fan, control panel (for automatic unit) and other components.

When it is an automatic control unit, the split diesel engine automatic control cabinet realizes the functions of automatic reset, input, automatic switching, automatic protection and other functions of the system. At the same time, it can also interface with the user’s fire center or automatic fire alarm device to realize remote control monitor.

When selecting a fire pump, understanding the advantages and suitable scenarios for electric fire pumps and diesel engine fire pumps is essential. Each type of pump has its unique features, providing different fire protection solutions to meet varying needs.

Electric fire pumps are ideal for environments with stable power supply. They typically have lower operational costs and higher efficiency. Electric pumps start quickly, produce less noise, and require less maintenance, making them the perfect choice for most modern buildings and commercial facilities. Their intelligent control system supports automatic start-stop, fault diagnosis, and remote monitoring, ensuring the system operates efficiently and safely.

Diesel engine fire pumps, on the other hand, are better suited for locations with unstable or no power supply. Diesel pumps can operate independently in the absence of electricity, ensuring a stable water source during emergencies. Although diesel pumps are usually more expensive and require more maintenance, they have exceptional emergency capabilities and can operate reliably in any environment, making them particularly suited for industrial parks, mining areas, and remote regions.

Choosing the right fire pump system should depend on the site’s power supply situation, operating costs, maintenance capabilities, and the required emergency response capacity. Whether opting for an electric fire pump or a diesel engine fire pump, we are committed to providing you with the most reliable and efficient fire protection solutions.

Diesel pumps can be combined with electric pumps, jockey pumps, etc. to form an automatic water fire-fighting water supply system, and can be linked with the fire control center.

When the pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set to start the motor to start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine to the rated speed . The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the pump set receives a signal that the pressure of the pipeline network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

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.
