EDJ series is a packaged fire pump set, generally an automatic fire water supply system. It consists of a main pump (driven by an electrical motor), a stand-by pump (driven by diesel engine), and a jockey pump. This model comes equipped with a separate controller, or one that is attached to the skid. The package also contains discharge valves, common header, and accessories.
Generally, the pipeline network's pressure is between low pressure P1 and high pressure P2. When the pressure is lower than P1, the jockey pump starts automatically until pressure rises to P2. If pressure drops to P3 due to high water consumption, the electric pump starts automatically. If the mains power fails or the electric pump fails, pressure drops to P4, triggering the diesel pump set to start automatically. The system ensures the fire water supply is maintained under all conditions.

Frequently Asked Questions
What components are included in the EDJ fire pump set?
The set includes a main electric motor pump, a standby diesel engine pump, a jockey pump, a control panel, discharge valves, and common piping headers.
Is this pump system compliant with international standards?
Yes, the EDJ series is designed to meet UL and NFPA20 standards for fire protection systems.
What happens if there is a power outage during a fire?
The system is designed with a diesel engine standby pump that starts automatically if the electric pump fails or if there is a loss of mains power.
Can the pump material be customized?
Yes, we offer various materials including Cast Iron, SS304, and SS316 to suit different environmental and liquid requirements.
How is the pressure maintained in the pipeline?
The jockey pump (pressure maintaining pump) handles small leaks and maintains pressure between set points P1 and P2 without starting the large main pumps.
What is the typical lead time for an order?
Standard diesel engine pump units typically require 25 working days for production and testing.
