System Configuration
The fire pump set includes three major components — a diesel engine pump, a jockey pump, and an automatic control panel — along with essential accessories for smooth operation.
1. Diesel Engine Pump
The diesel engine pump can be configured as a single-stage pump, horizontal split-case pump, end-suction pump, or multistage pump. Material choices include cast iron, stainless steel, or bronze impellers for enhanced durability and corrosion resistance.
Each unit comes complete with a fuel tank, cooling water tank, fan, and control box, ensuring stable operation during fire emergencies and power outages.
2. Jockey Pump
The jockey pump maintains system pressure to prevent frequent operation of the main fire pump. Available in horizontal or vertical configurations, it has a higher head but smaller capacity compared to the main pump.
- Casing Material: Cast iron
- Shaft and Impeller: SS304 stainless steel
3. Control Panel
The automatic control panel manages both the diesel and jockey pumps. It features overload and overcurrent protection, ensuring reliable system performance and safety under all conditions.
Included Accessories
The diesel engine fire pump system comes equipped with all necessary fire pump accessories for easy installation and maintenance:
- Check valve, gate valve
- Pressure vessel (0.6 MPa, 1.0 MPa, 1.6 MPa options)
- Pressure gauge and pressure sensor
- Common suction and discharge piping
- Flexible rubber joints and flanges
- Common base plate
Earthquake-resistant electrical contact pressure gauges are fitted with buffer valves to minimize false alarms caused by pressure fluctuations. Flexible rubber joints help absorb vibration and noise generated during pump startup, preventing pipeline damage and ensuring longer system life.
