A multi-nozzle eductor is a jet-driven device used to mix, convey, or pump liquids, solids, or gases using pressurized fluid such as water, air, or steam. It operates on the Venturi principle, where high-velocity fluid passing through multiple nozzles creates suction, efficiently drawing in and mixing secondary materials.
Compared to single-nozzle eductors, multi-nozzle eductors offer:
- Higher efficiency – Better suction and mixing power.
- Uniform dispersion – Even chemical or material distribution.
- Versatile applications – Works with liquids, gases, and solids.
How Does a Multi-Nozzle Eductor Work?
Multi-nozzle eductors function by utilizing fluid pressure differentials. The high-speed jet stream from multiple nozzles creates a vacuum, drawing in external substances, blending them, and ejecting the mixture efficiently. This makes them ideal for applications that require precise material handling without moving parts.
