The EDJ series is a professionally packaged fire pump set, designed as an automatic fire water supply system. It typically consists of a main pump driven by an electrical motor, a standby pump driven by a diesel engine, and a jockey pump to maintain system pressure. This model comes equipped with either a separate controller or one attached to the skid. The complete package also includes discharge valves, a common header, and necessary accessories for immediate installation.
The system maintains pipeline network pressure between a set low pressure (P1) and high pressure (P2). When pressure drops below P1, the jockey pump starts automatically until it reaches P2. In the event of high water consumption or leakage where pressure drops further to a minimum point (P3), the electric main pump activates. If the main power supply fails or the electric pump malfunctions, the pressure continues to drop to the ultimate level (P4), triggering the diesel engine pump set automatically. All main pumps are designed for manual stoppage after fire-fighting operations are concluded.
