XBD Series Fire Fighting Pumps

The XBD Series Fire Fighting Pumps are developed in compliance with China's Building Design Code for Fire Protection and Fire Protection Code for High-Rise Civil Buildings. Designed with advanced engineering, these pumps deliver superior applicability and performance, making them the preferred choice for fixed fire protection water supply systems in industrial and commercial buildings.

Key Features:

1、Compact Vertical Design:

• Minimal footprint due to vertical structure.
• Single-stage impeller reduces overall height (approximately half the height of traditional multi-stage DL-series vertical pumps), ensuring stability and ease of installation even in low-ceilinged underground pump rooms. This maximizes building commercial utility and simplifies installation, maintenance, and repairs.

2、Flat Flow-Head Curve:

• Maintains near-constant head pressure despite significant flow rate variations, eliminating the need for frequency converters to achieve constant-pressure operation. Effectively prevents overpressure issues during low-flow fire suppression, ensuring system safety.

3、Corrosion-Resistant Components:

• Bronze alloy impeller wear rings and sealing rings resist corrosion and seizing. Single-stage impeller design minimizes dynamic friction points, enhancing reliability and ensuring the pump remains in optimal fire-ready condition.

4、Leak-Free Shaft Sealing:

• High-quality mechanical seals provide zero leakage, keeping the pump room dry and clean.

5、Direct-Drive Motor:

• Extended motor shaft directly drives the impeller, ensuring precise coaxial alignment and stable operation. Specially designed motors minimize noise, offering high precision, reliability, and extended service life.

6、Flexible Installation:

• Discharge port orientation 0°, 90°, 180°, or 270° relative to the suction port, simplifying pipeline layout.

• Flow Rate: 5–50 L/s
• Pressure: 0.4–2 MPa
• Temperature: ≤80°C
• Media: Clean water without solid particles or liquids with physical/chemical properties similar to water.

Applications

• Fire Protection Systems:
  • Hydrant systems, automatic sprinkler systems, and water mist systems in industrial and commercial buildings.
• Other Applications:
  • Boiler constant-pressure water supply, municipal engineering, and industrial processes requiring constant-pressure water delivery.
