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.

When the water supply doesn’t have enough pressure, a fire pump can be an excellent solution to the problem, as long as the pump is sized correctly. The fire pump is selected by five factors: liquid delivery volume, device lift, liquid properties, pipeline layout and operating conditions.

NFPA 20 requires fire pumps to be powered by a continuously available power source, usually identified as an uninterruptible power source. In many cases, this requirement requires a backup generator to be provided as a backup power source in the event of a power failure, in which case the fire pump controller must be equipped with an automatic transfer switch. The choice of fire pump depends on the building infrastructure and available space. The most common choices for fire pump drives are electric motors and diesel engines.
