Customer Benefits
Reliable Emergency Operation
The diesel engine provides excellent starting characteristics and does not depend on external electrical power, ensuring reliable fire pump activation even during power outages or electrical system failures.
Strong Overload Capacity
The diesel engine-driven configuration delivers robust overload capacity, maintaining the required flow and pressure under demanding fire protection conditions where extended operation at or above rated capacity may be required.
Easy Maintenance Access
The split-case pump design allows the upper casing to be removed without disturbing the pipework, providing direct access to the impeller and internal components for inspection and maintenance.
High Automation Level
Advanced control systems enable automatic start-up, pressure monitoring and fault detection, reducing the need for manual intervention during emergency events and improving system reliability.
Compact Space-Efficient Design
The rational structural layout minimises the footprint of the complete fire pump set, making it suitable for pump rooms with limited installation space.
Versatile Fire Protection Coverage
Suitable for fire hydrant systems, automatic sprinkler systems and water mist suppression systems across residential, commercial, industrial and institutional applications.

Selection Guidance
To select the appropriate diesel engine-driven split-case fire pump, please provide the following information:
- Required flow rate (L/s)
- Required pressure (MPa or bar)
- Fire protection system type (hydrant, sprinkler, water mist)
- Building type and occupancy classification
- Available installation space and pump room dimensions
- Local fuel supply and storage requirements
- Required duty point on the pump curve
- Applicable fire protection standards and codes
Final model selection should be confirmed according to the actual duty point, system requirements and applicable fire protection standards.
Installation and Maintenance
Installation Guidance
The fire pump set should be installed on a rigid, level foundation with adequate clearance for inspection, maintenance and diesel engine ventilation. The suction and discharge piping must be independently supported to prevent load transfer to the pump flanges. A properly sized fuel tank with adequate fuel reserve must be provided for the diesel engine.
Pre-Commissioning Inspection
Before commissioning, confirm the following:
- Pump and diesel engine are securely mounted and level
- Suction and discharge piping connections are complete and leak-free
- Fuel tank is filled with the correct grade of diesel fuel
- Engine coolant and lubricating oil levels are correct
- Starting batteries are charged and connections are secure
- Control panel wiring and settings are verified
- Rotational direction matches the arrow indicated on the pump casing
Routine Maintenance
Regular inspection should include:
- Weekly no-load test run of the diesel engine
- Monthly load test under fire protection system conditions
- Checking engine oil, coolant and fuel levels
- Inspecting batteries and charging system condition
- Verifying that the pump maintains the required flow and pressure during test runs
- Inspecting all pipeline connections for signs of leakage
