Product Overview
The XBC series diesel engine-driven single-stage fire pump set integrates a high-quality domestic or imported diesel engine with a single-stage centrifugal fire pump, delivering reliable fire protection water supply independent of the electrical grid. With flow rates from 15 to 300 L/s, discharge pressures up to 1.8 MPa, and power ratings from 30 to 400 kW, this pump set covers a broad range of fire protection scenarios across residential, commercial, industrial, and institutional buildings.

Intelligent Automatic Control System
The XBC pump set features a comprehensive automatic control system designed for unmanned operation. When the unit receives a remote start command, detects a power failure, or identifies an electric pump fault, it will automatically initiate and begin pumping without human intervention.
Real-Time Process Parameter Display
The control panel continuously displays the current operating state and key parameters:
- Operating states: Start, Run, Speed-Up, Speed-Down, Idle, Full Speed, Stop
- Process parameters: Engine speed (RPM), oil pressure, coolant temperature, oil temperature, battery voltage, cumulative running hours
Comprehensive Alarm & Protection Functions
The system monitors critical conditions and triggers alarms or automatic shutdowns to protect the engine and ensure readiness:
- Start failure alarm
- Low oil pressure alarm with automatic shutdown
- High coolant temperature alarm
- High oil temperature alarm
- Low battery voltage alarm
- Low fuel level alarm
- Overspeed alarm with automatic shutdown
Multiple Starting Modes
The pump set supports several starting methods to match different site conditions:
- Local manual start/stop — for on-site operator control
- Remote control center start/stop — for integration with building fire alarm systems
- Automatic start on mains power loss — ensures fire protection continuity during grid outages
Standby Readiness Features
Automatic Battery Charging
During standby, the control system automatically float-charges the starter battery. When the engine runs, its onboard charging generator takes over battery charging. The maintenance-free battery design eliminates the need for regular electrolyte refills.
Dual Battery Start Circuit (Optional)
If the primary battery set fails to crank the engine, the system automatically switches to a secondary battery set, providing redundant starting capability for critical installations.
Mechanical Emergency Start (Optional)
In the event of a control cabinet failure, a manual-magnetic integrated starting device allows the diesel engine to be started mechanically, ensuring the pump can still operate under adverse conditions.
Water Jacket Pre-Heater (Optional)
For installations in low-temperature environments, an optional water jacket pre-heater warms the engine block to facilitate reliable cold starts.
Adjustable Operating Speed
When the pump’s actual flow or head does not match site requirements, the diesel engine’s rated speed can be adjusted to fine-tune performance, offering flexibility across diverse fire protection designs.
Wide Pump Type Compatibility
The XBC series can be configured with multiple pump types to match system requirements:
- Horizontal single-stage single-suction centrifugal pump
- Horizontal multistage pump
- Single-stage double-suction pump
- Long-shaft pump
This flexibility allows the diesel-driven fire pump set to cover a wide range of flow and pressure combinations.
Typical Applications
- Fire hydrant systems in residential and commercial buildings
- Automatic sprinkler fire suppression systems
- Water spray fire protection systems
- Industrial facility fire water supply
- Hotel, hospital, and office building fire protection
- Remote sites without reliable grid power

FAQ
Q1: How does the XBC diesel fire pump start automatically during a power outage?
The control system monitors the mains power supply. When it detects a power failure or receives a fire alarm signal, it automatically initiates the diesel engine start sequence. The dual-battery circuit (optional) provides redundant cranking power if the primary battery is depleted.
Q2: What alarms does the system provide?
The system monitors seven critical parameters: start failure, low oil pressure, high coolant temperature, high oil temperature, low battery voltage, low fuel level, and overspeed. Each alarm can trigger visual/audible alerts, and critical conditions (low oil pressure, overspeed) initiate automatic engine shutdown to prevent damage.
Q3: Can the engine speed be adjusted on site?
Yes. If the pump’s flow or head does not match the system design requirement, the diesel engine’s rated speed can be adjusted within its operating range to fine-tune the output.
Q4: Is the battery maintenance-free?
The standard configuration uses a maintenance-free battery that does not require regular electrolyte additions. The control system automatically float-charges the battery during standby, and the engine’s onboard generator charges it during operation.
Q5: What optional features are available for cold environments?
An optional water jacket pre-heater warms the engine block before starting, ensuring reliable ignition in low-temperature conditions. This is recommended for outdoor installations or unheated pump rooms in cold climates.
