1. Single-stage centrifugal structure
The product adopts a single-stage centrifugal pump structure. After water enters the pump body, the high-speed rotation of the impeller generates centrifugal force, achieving pressurized water delivery. The single-stage structure is relatively simple, facilitating equipment installation, operation inspection, and daily maintenance, and is suitable for various fixed fire water supply systems.
2. Direct-Drive Motor
The motor and pump body are directly coupled, with power transmitted directly to the impeller via the pump shaft, reducing intermediate transmission links. This direct-drive design improves power transmission efficiency and makes the overall equipment more compact, suitable for engineering environments with limited space in fire pump rooms.
3. High Concentricity Pump Shaft
The pump shaft is coaxially connected to the motor, and the high concentricity of the shaft system reduces eccentricity and mechanical vibration during operation. Stable shaft operation helps the equipment maintain a smooth working state while reducing operating noise, creating favorable mechanical conditions for the long-term operation of the fire pump.
4. High-Efficiency Impeller Water Delivery
The impeller is the core component for pressurized water delivery. The blades drive the water flow at high speed, giving the water energy. A well-designed impeller hydraulic system can provide corresponding flow and pressure according to different operating conditions, meeting the water supply needs of fire hydrants, automatic sprinklers, and other fire protection systems.
5. Stable Pressure Output
Fire protection systems have specific requirements for water supply pressure. The product uses a stable motor to drive the pump, continuously providing the required pressure under design conditions. Different models can be selected based on building height, pipeline resistance, and design flow rate, ensuring a better match between pump performance and fire protection network requirements.
6. Reliable Mechanical Seal
The equipment employs a mechanical seal structure. The sealing components can be made of stainless steel, tungsten carbide, and media-resistant rubber, helping to reduce liquid leakage at the pump shaft location while ensuring wear resistance and service life. Good sealing performance is crucial for the long-term stable operation of the fire pump.
7. Compact Installation Structure
The motor and pump body adopt a compact layout, effectively reducing the overall space occupied by the equipment. For locations with limited installation space, such as fire pump rooms and equipment rooms, this structure improves space utilization and facilitates integration with inlet and outlet pipelines and other fire protection equipment.
8. Multiple Performance Specifications Available
The product offers various flow rate, head, diameter, power, and speed configurations, allowing for model matching to specific fire protection projects. According to official website data, its flow rate ranges from 1 to 300 L/s, its head ranges from 0.15 to 1.6 MPa, and its power ranges from 0.75 to 160 kW, covering the selection needs of fire-fighting water supply projects of different scales.
9. Wide Applicability to Fire Protection Systems
This type of electric fire pump is mainly used in fixed fire hydrant systems and automatic sprinkler systems, and can also be applied to building, industrial, and municipal fire-fighting water supply projects. Under the condition of clean water and corresponding media, it can serve as the main pressurized water supply equipment in fire protection systems.
10. Easy Operation and Maintenance
The product is designed with a pressure gauge interface, drainage structure, and venting device, facilitating personnel to monitor operating pressure, vent equipment, and perform maintenance. During use, the motor, pump shaft, mechanical seal, impeller, and inlet/outlet water pipes can be checked regularly according to actual operating conditions to keep the equipment in good operating condition.
Single-stage vertical electric fire pumps are characterized by direct-drive motor, highly concentric pump shaft, single-stage centrifugal structure, stable pressure output, and compact installation design. They provide reliable pressurized water delivery for fixed fire hydrant systems, automatic sprinkler systems, and other fire water supply projects. The products are available in various flow rates, head, diameters, and power specifications, allowing for selection based on building height, fire water demand, and pipeline pressure requirements. For fire protection projects that prioritize operational stability, efficient installation space utilization, and ease of maintenance, this type of electric fire pump serves as a crucial pumping device in fixed fire water supply systems.
