Applications
The pump is ideal for fire protection in:
– Residential environments
– Commercial environments
– Industrial environments
The EDJ Series is a fully integrated fire-fighting water supply system that combines an electric main pump, diesel standby pump, and jockey (pressure maintenance) pump. It is specifically engineered to provide reliable, high-pressure water delivery during fire emergencies. With multi-power redundancy and automatic switching, the system ensures continuous water supply even during complete electrical grid failures.
