The diesel engine multistage fire pump series pairs premium domestic or imported diesel engines with a range of pump configurations — including single-stage, horizontal multistage, single-stage double-suction, and long-shaft designs — delivering a reliable, self-contained fire protection solution for demanding industrial and commercial applications.
Key Performance Parameters
| Flow Rate (Q) | 10 – 100 L/s |
| Head Pressure (H) | 0.20 – 2.40 MPa |
| Power (N) | 30 – 450 kW |
| Speed (n) | 1,500 / 1,800 / 2,900 r/min |
Operating Conditions
- Ambient temperature: 5 °C – 40 °C
- Relative humidity: ≤ 80%
- Under abnormal conditions, diesel engine output may fall below rated power; selecting a higher-rated engine is recommended to ensure reliable operation.
Product Features
Wide Pump-Type Selection
The system supports multiple pump configurations — single-stage single-suction centrifugal, horizontal multistage, single-stage double-suction, and long-shaft pumps — covering a broad range of flow and pressure requirements for diverse fire suppression systems.
Multiple Starting Methods
Supports on-site manual start, remote start from the control center, and automatic interlock start triggered by mains power failure, allowing flexible configuration based on each fire system’s control requirements.
Automatic Operation Control
Upon receiving a remote start signal, mains power loss, or electric fire pump failure, the diesel fire pump set automatically starts and executes the complete programmed control sequence without operator intervention.
Real-Time Monitoring
The control system displays real-time status including start-up, running, acceleration, deceleration, idling, and shutdown, while continuously monitoring diesel engine speed, oil pressure, water temperature, oil temperature, battery voltage, and cumulative running hours.
Comprehensive Alarm Protection
Equipped with alarms for start failure, low oil pressure, high water temperature, high oil temperature, low battery voltage, low fuel level, and overspeed — with corresponding protective actions or shutdown controls triggered automatically by fault type.
Status Feedback & Remote Linkage
Provides output signals for running status, start failure, general alarm, and control power status, enabling seamless integration with fire control centers and other building management systems.
Automatic Battery Charging
During standby, the control system maintains the battery with automatic float charging; during diesel engine operation, the engine-driven charging generator keeps the battery topped up, ensuring reliable start-up power at all times.
Typical Applications
- Industrial fire protection systems
- Commercial building fire suppression networks
- Oil & gas facility fire water supply
- Chemical plant emergency fire response
- Municipal fire hydrant network boosting
- Power station fire protection backup
