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.

Fire pump controllers are devices that monitor and control the operation of fire pumps. They ensure that the pump starts automatically during an emergency, regulate pressure, and provide safety features. Controllers play a crucial role in the overall functionality of the fire pump system.

EDJ is our flagship product:
The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the voltage stabilizer pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.

Pressure relief valves prevent over-pressurization in the fire pump system. They ensure safe operation by releasing excess pressure, protecting the pump and connected piping from damage.

Diesel fire pumps are generally used as backup equipment, and will only start automatically when the fire signal arrives, the electric pump fails or the power is cut off. After the ultra-low pressure starting device is equipped, the matching electric water pump control cabinet should also be equipped with an ultra-low pressure starting device, and the pressure difference between the two should be the lower limit. This series of products has a large range of lift and flow, which can fully meet the needs of the dock , warehouse, liquefied gas station, petrochemical, airport, power plant, textile and other industrial and mining enterprises fire water supply.
