The double-suction fire pump has the characteristics of high lift and large flow, and is widely used in fire fighting. The impeller of this pump type is actually a combination of two back-to-back impellers, and the water flow from the impellers merges into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is horizontally opened, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is conducive to the arrangement and installation of the pump and the inlet and outlet pipes; the impeller structure of the double suction pump is symmetrical, there is no axial force, and the operation is relatively stable.

The EDJ Diesel Engine Fire Pump System is a powerful and reliable firefighting equipment designed for fire suppression and emergency rescue operations. It boasts high-performance capabilities in water extraction and pressure delivery, enabling rapid supply of large volumes of water. The system operates independently, ensuring its reliability even in challenging situations. With its lightweight and portable design, coupled with versatile functionality, the EDJ Diesel Engine Fire Pump System is suitable for various scenarios. Whether you are part of a fire department or an industrial enterprise, the EDJ Diesel Engine Fire Pump System is your indispensable rescue partner.

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. This dual-power configuration offers both reliability and flexibility, providing comprehensive coverage for fire safety needs. With smart controls and automatic switching mechanisms, the transition between electric and diesel engine pumps is seamless, minimizing system downtime. Equipped with advanced safety features, including monitoring and alarm systems, real-time status updates allow for prompt action in case of any irregularities.

Diesel fire pumps offer distinct advantages over other types of fire pumps, such as electric or jockey pumps. Unlike electric pumps, which rely on grid power and may be vulnerable to power outages, diesel fire pumps can operate independently, making them suitable for use in areas with unreliable electricity or during emergencies. Jockey pumps, on the other hand, are typically used to maintain pressure in fire sprinkler systems but may not provide the same flow rates or firefighting capacity as diesel fire pumps.

The fire pump system includes diesel engine pump + electric motor pump + jockey pump.
Its power: 1.0 to 20kw, flow: 15-300gpm, head: 3-10bar, 50/60hz. Material: Cast iron or SS, bronze impeller.

The fire pump is designed to divert water when a fire is detected by the sprinkler system or other fire-detection device. The pump will then draw water from the water supply source and deliver it to the sprinkler system, fire hoses, or other fire suppression devices.

EDJ fire pump set is our main 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 signal from the electric contact pressure gauge and start the diesel engine pump within 5 seconds, and reach the rated working condition within 20 seconds to ensure the normal operation of the fire extinguishing work.

One way of choosing a diesel generator as a backup power source for fire protection is because in fire protection, two power supplies are required, which can be two power plants and two transformers, or one line of city power and one line of diesel generator set power supply. Meet the requirements of fire backup power.
