System Components
🟩 Electric Pump
This component serves as the primary power source under normal conditions. Various pump types are available, including end-suction, split-case, and multistage models. Material options such as cast iron, stainless steel, and bronze impellers ensure durability in diverse environments.
- Power: 5.5–710 kW
- Flow: 10–420 L/s
- Pressure: 0.3–1.2 MPa
🟨 Diesel Pump
In case of power failure, the diesel engine pump acts as a reliable backup. It connects via a high-elastic coupling or universal joint and includes an integrated water tank, fuel tank, control panel, and cooling system.
- Power: 7.0–810 kW
- Flow/Pressure: Same as electric pump
🟦 Jockey Pump (Optional)
Although typically excluded from small flow sets, jockey pumps are included in large flow units. These are high-head, low-flow pumps that maintain system pressure and reduce energy consumption.
- Power: 0.75–4 kW
- Head: 0.45–1.36 MPa
- Flow: 2–4 m³/h
🟥 Control Panel
This intelligent control unit ensures full automation, offering features such as overload and overcurrent protection. Moreover, remote monitoring is possible through a smartphone app for added convenience.
🟧 Accessories
A comprehensive set of accessories supports optimal operation:
- Check valves, gate valves
- Diaphragm pressure tanks (0.6 MPa, 1.0 MPa, 1.6 MPa)
- Pressure gauges and sensors
- Import/export pipes, soft joints, flanges, and baseplates
Classification by Flow
To meet different usage scenarios, fire pump sets are categorized into:
- Small Flow Units (30–100 GPM): Generally include only motor and engine pump sets
- Large Flow Units (120–5000 GPM): Equipped with motor, engine, and jockey pump sets
Wide Range of Applications
Because of its flexibility and certifications, the EDJ Small Flow Fire Pump Set is suited for:
- Fire protection in high-rise buildings, institutions, and residential complexes
- Automatic sprinkler systems and fixed firefighting installations
- Emergency water supply in industrial facilities, chemical plants, power stations, and municipal projects
- Critical safety systems in airports, seaports, warehouses, textile mills, oil tankers, and military bases
