1. High-capacity design for large-scale fire water supply systems

The core advantage of high-capacity split-case fire pumps lies in their robust water delivery capability, making them suitable for large fire-fighting piping networks, industrial fire pump stations, and integrated fire water supply systems. The broad flow rate range allows for the selection of specifications that match actual water demand, ensuring the pump unit is optimally suited to the scale of the fire protection system.

 

2. Horizontal split-case structure facilitates equipment maintenance

The pump body utilizes a horizontal split-case design; the upper casing can be removed, providing convenient access to the internal impeller, shaft, and sealing components. Maintenance can be performed without extensive adjustment of the suction and discharge piping, thereby reducing the maintenance workload and improving overall efficiency.

 

3. Double-suction impeller enhances high-volume delivery capability

The double-suction design allows the medium to enter from both sides of the impeller, ensuring excellent suction performance during high-flow operation. For large-scale fire water supply systems, this structure enhances hydraulic delivery capacity and meets the demands for continuous, high-volume water supply.

 

4. Wide range of flow and head configurations

This series of split-case fire pumps accommodates various combinations of flow rates and heads. Product specifications indicate flow rates up to 1,528 L/s and heads up to 160 m, enabling selection based on specific building heights, piping network resistance, and fire water volume requirements. Final configuration should be determined based on system calculations.

 

5. Large-diameter ports suitable for high-flow piping networks

With nozzle diameters ranging from 150 to 800 mm, the large-diameter inlet and outlet design effectively meets the hydraulic delivery requirements of large-scale fire-fighting piping networks. For scenarios with high water demand—such as fire pump stations, industrial parks, and warehousing facilities—pump models and connection specifications can be selected to match the piping network dimensions.

 

6. Stable Operation to Meet Fire Water Supply Demands

Fire water supply equipment must maintain stable operation under critical conditions. Split-case double-suction pumps utilize a proven centrifugal pump design; optimized impeller and flow-path configurations ensure continuous water delivery while balancing operational stability with maintenance requirements, making them ideal for long-term installation in fixed fire water supply systems.

 

7. Material Combinations Suited to Various Media

Depending on specific operating conditions, split-case fire pumps can be configured with various material combinations to handle clear water, industrial water, river water, seawater, and certain specialized media. Selection for fire systems should take into account water quality, temperature, corrosiveness, and the operating environment when determining materials for components such as the pump casing, impeller, and shaft.

 

8. Suitable for Diverse Large-Scale Engineering Scenarios

High-flow split-case fire pumps are applicable to fire pump stations, industrial facilities, water supply projects, marine engineering, and petrochemical refining operations. In industrial fire systems, they serve as core pumps, handling high-volume water transfer from fire reservoirs to the piping network, and operate in conjunction with control, valve, and piping systems.

 

9. Power Configurations Meeting Diverse System Requirements

The product range covers power outputs from 18.5 to 1600 kW and rotational speeds of approximately 1500 to 2900 r/min, allowing for power configurations matched to specific flow rates, heads, and system conditions. Selection for specific projects should comprehensively consider design flow rates, pressure requirements, pipeline losses, and equipment operating conditions.

 

10. Balancing Water Delivery Performance with Long-Term Maintenance

Large-scale fire pumps require attention not only to initial delivery capacity but also to long-term maintenance and operational management. The split-case design combines high-flow delivery capabilities with ease of maintenance; it meets fire water supply demands while facilitating the inspection and servicing of components such as the impeller, shaft assembly, and seals, making it an ideal choice for projects requiring high reliability and maintenance efficiency.

Key features of high-capacity, axially split-case fire pumps include a horizontal split-case design, double-suction impellers, large-diameter ports, and a wide operating range for flow and head. These pumps are designed to meet the high-flow fire water supply requirements of large-scale fire pumping stations, industrial facilities, and warehousing complexes. Their structure facilitates easy maintenance, and they can be specifically selected based on the flow, head, pipe diameter, and fluid characteristics of individual projects, making them vital components of large-scale, stationary fire water supply systems.
