1. Compliant with NFPA 20 standards, ensuring compliance with international projects

ZJ-BETTER electric end-suction fire pumps are designed and manufactured in strict accordance with NFPA 20 (Standard for Fixed Fire Pumping Systems). This standard, established by the National Fire Protection Association (NFPA) in the United States, is one of the most internationally recognized technical specifications for fire pumps. The pump body structure, hydraulic performance, motor selection, control logic, and safety redundancy all meet the requirements of this standard, ensuring the product can smoothly pass project acceptance and government approvals in regions with strict fire safety standards, such as North America, the Middle East, and Southeast Asia. The manufacturer can also provide a complete set of English certification documents, including performance test reports, dimension drawings, installation manuals, CE certification certificates, and material certificates, greatly facilitating overseas customers in bidding and project delivery.

 

2. Efficient hydraulic design enhances system energy efficiency ratio

This end-suction fire pump employs advanced CFD fluid simulation technology to optimize the hydraulic model, with a rational pump cavity flow path design that reduces hydraulic losses and improves operational efficiency. Test data shows that the overall efficiency of the ZJ-BETTER end-suction pump generally exceeds 80%, meeting high-head fire protection requirements while minimizing electrical energy consumption and reducing system operational costs. The high-efficiency impeller structure is manufactured using precision casting technology, ensuring stable water flow without noticeable pulsation. It is suitable for prolonged continuous operation without causing water hammer impacts or pipeline vibrations, thereby further enhancing system stability.

 

3. Compact structure with minimal space requirements

Compared to traditional split-case pumps, the end-suction pump features a more compact structure with clearly defined inlet and outlet directions, making it ideal for installation in pump rooms or equipment rooms with limited space. The ZJ-BETTER electric end-suction fire pump adopts a horizontal layout, with the base directly installable on a foundation platform. Combined with the manufacturer's pre-installed skid-mounted solution, the配套 motor, coupling, base, and foundation can be tested and adjusted before shipment, significantly reducing on-site installation and commissioning time and construction difficulty, and saving civil engineering costs. The product supports various pipeline connection methods, including left-in/right-out, right-in/left-out, and vertical inlet/outlet, enhancing project design flexibility.

 

4. High-quality motor drive for stable operation and low noise

ZJ-BETTER fire pumps are equipped with high-quality electric motors featuring copper-core windings, high insulation ratings, and high-efficiency stator structures. These motors offer strong overload capacity, smooth startup, and stable continuous operation. The electric motor is connected to the pump body via a high-precision coupling, resulting in minimal vibration, low noise, and low failure rates during operation. This makes the system particularly suitable for environments with strict noise control requirements, such as office buildings, hospitals, and data centers.

 

5. Diverse material options to accommodate various medium conditions

To adapt to different operating environments and conveyed media, ZJ-BETTER offers a wide range of customizable pump body materials, including gray cast iron, ductile iron, 304/316 stainless steel, and bronze alloys, capable of meeting the requirements of various conditions such as freshwater, seawater, and weakly corrosive liquids. The impeller material can also be selected according to user requirements, including brass, stainless steel, or cast iron, further enhancing the pump's corrosion resistance and service life. All materials comply with RoHS environmental standards and international metal composition testing requirements, making them particularly suitable for international engineering projects with strict environmental and durability requirements.

 

6. Integrated intelligent control cabinet, supporting automatic interlocking and remote monitoring

The electric end-suction fire pump can be equipped with ZJ-BETTER's independently developed intelligent electrical control cabinet, which integrates PLC controllers, displays, alarm systems, and electrical protection functions. It supports automatic start/stop, pressure feedback, dual pump shift operation, fault self-diagnosis, and remote control functions. The control cabinet is compatible with multiple communication protocols and can be integrated into the user's BMS/SCADA system to enable real-time monitoring and remote management of the pump group's operational status. Through the fire control center or cloud-based system, centralized monitoring and fault warning of pump room equipment across multiple locations nationwide can be achieved, enhancing the intelligence level of the fire protection system.

 

7. Multiple start-up methods available to suit different project requirements

ZJ-BETTER offers multiple start-up methods for electric fire pumps, including direct start, star-delta start, autotransformer voltage reduction start, and variable frequency soft start, to accommodate different grid conditions and start-up current restrictions. Among these, the variable frequency soft start control scheme is particularly suitable for high-rise buildings and areas with limited grid capacity, effectively suppressing start-up surge currents, extending motor lifespan, and reducing the configuration pressure on the distribution system. The control cabinet can also be configured with a “primary + standby” dual-pump automatic switching function, which automatically switches to the standby pump when the primary pump fails or pressure is insufficient, ensuring system reliability and redundancy.

 

8. Strict factory testing to ensure stable delivery of equipment

ZJ-BETTER conducts rigorous performance testing on every fire pump before shipment, including water pressure testing, power testing, flow and head testing, airtightness testing, and motor no-load and load testing. The testing process uses automated test benches, with real-time data recording and tracking to ensure that the performance curves of each pump set are accurate, stable, and traceable. All products are equipped with a unique product number and test report for convenient post-delivery maintenance and technical support.

 

9. Extensive Application Cases, Validating Quality and Reputation

ZJ-BETTER electric end-suction fire pumps have been widely applied in numerous large-scale engineering projects both domestically and internationally, such as the Singapore Municipal Building, Dubai Commercial Complex, African Hospital Project, Vietnam Industrial Park, and Saudi Arabia Logistics Warehouse Center. Customers have consistently feedback that the pump system operates stably, is easy to install, and features intelligent control, making it one of the most cost-effective configuration solutions for fire protection systems. The company also provides customers with 24/7 technical support and spare parts assurance, offering remote guidance for installation and commissioning to assist customers in swiftly completing project delivery.

 

10. Flexible customization services to meet personalized project requirements

ZJ-BETTER understands that each fire protection project has unique requirements in terms of configuration, operating conditions, and regional specifications, so it offers highly customized services. Customers can customize configurations based on flow rate, head, voltage frequency, control logic, pipe direction, motor brand, and other requirements. The company can also provide customers with project-specific selection calculation reports, 3D installation diagrams, CAD layout plans, and technical documents for international tenders, helping customers quickly respond to project bidding and construction requirements and enhance the overall competitiveness of their solutions.
