Jet pumps utilize high-velocity drive fluid to entrain secondary fluid, enabling motorless pressurization and mixing in sprinkler systems. Ideal for explosive/space-limited environments, their nozzle accelerates fluid to 15-30m/s, creating vacuum in the mixing chamber to suck in fire-suppressant.
Three Key Roles in Sprinkler Systems
Ultra-Fast Fire Response
- Zero start delay: Achieves full water curtain coverage in 3s at ≥0.7MPa (traditional pumps need 15s)
- Bosch tests: Spray density reaches 8L/(min·m²) within 2.8s
Precision Chemical Mixing
- Blends fire retardants (e.g., 3% fluoroprotein foam) in mixing chamber
- Mixing uniformity error <±0.5% (vs. >±3% for agitators)
Energy-Saving & Explosion-Proof
- No moving parts, power consumption ≈1/10 of electric pumps (200W typical)
- ATEX-certified for hazardous areas like oil tank farms
Application Comparison
Scenario | Jet Pump Solution | Electric Pump Solution |
Warehouse fire protection | Connects directly to water mains, no electricity | Requires dedicated power + generator |
Mobile fire units | Weight <15kg, portable by one person | Typical weight 80-120kg |
High-pressure water mist | Operating pressure up to 20MPa | Max. pressure usually ≤15MPa |
Corrosive media | Full fluoroplastic body resists strong acids | Needs special alloys, 3x cost |
