Mutistage EEJ Fire Pump Set comprises a combination of two sets electric motor driven pump and jockey pumps that supply for fire suppression systems.

The EJ model is basically a combination of an electric drive and a jockey pump. They consist primarily of an end suction pump driven by an electric motor, with no backup pump. It is also combined with a jockey pump for maintenance to form a complete skid.

The complete EJ-style skid is assembled with all discharge line accessories and connected to the skid-mounted control panel.

Control Panel: The control panel houses electrical controls and monitoring devices for the fire pump. It typically includes components such as motor starters, switches, gauges, and alarms. The control panel allows for manual or automatic operation of the fire pump and provides critical information about pump performance and status.

Fire pumps are often required to have backup power sources, such as diesel generators or uninterruptible power supplies (UPS), to ensure they function during power outages.

The size and capacity of a firefighting pump depend on factors such as the size of the area to be protected, the potential fire hazard, and the water supply available. Calculating factors such as flow rate, pressure requirements, and the distance water needs to be delivered can help determine the appropriate pump size and capacity.

Industrial manufacturing plants often deal with hazardous materials, heavy machinery, and complex processes, making fire safety a critical concern. Fire pumps are essential in these facilities for delivering sufficient water pressure to fire suppression systems like sprinklers, standpipes, and specialized suppression systems, such as foam or gas-based systems used for chemical fires. Jockey pumps help maintain pressure in these extensive systems, ensuring they are always ready to activate immediately. In many industrial plants, fire pumps need to handle large volumes of water to cover expansive areas like production floors, storage facilities, and hazardous material zones. Additionally, fire suppression systems must be designed to address specific risks, such as oil-based fires, electrical hazards, or flammable chemicals. Fire pumps in these environments require regular maintenance and testing to ensure they remain reliable, especially given the high risk of equipment malfunction or accidents in such settings. Integrating the fire pump system with automated fire detection systems, alarms, and emergency response protocols is critical for minimizing damage and protecting workers in the event of a fire.

The diesel engine fire pump is suitable for unattended emergency water supply systems. The product has the characteristics of good technology, high degree of automation, superior performance, complete protection functions, reasonable structure, simple installation, and high cost performance. pipe network pressure.

The diesel engine fire pump can form an automatic water fire water supply system with electric pumps and jockey pumps, and can be linked with the fire control center.
When the diesel engine fire 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, start the motor, start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine until 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 diesel engine fire pump set receives a signal that the pressure of the pipe 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.
