Venturi Eductors
CPVC Venturi
Venturi Eductors
Works by forcing water through a conical body which initiates a pressure differential between the inlet and outlet ports. This creates a vacuum inside the injector body, which creates suction at the injection port. The chemicals that are injection are rapidly dispersed through this high velocity “rapid mix” section.
Benefits:
-
Can be used for drawing liquids into a chemical feed system without the use of a pump
-
High chemical diffusion (up to 95%)
-
Excellent choice for gas/liquid injection (Ozone, CO2, Oxygen, Air)
-
Does not easily plug or lose efficiency over time compared to a porous injector
-
No moving parts
- Low cost

Dilution System Using a Venturi Eductor
The dilution system shown below is for diluting 12.5% sodium hypochlorite (NaOCl) to a more stable 3-5% concentration solution for potable water disinfection. The eductor combines the two flows of potable water and concentrated NaOCl and thoroughly mixes the flows before being stored in a storage tank.Turning the dilution system on is simple. The water valve is turned on. This motive water will draw the concentrated NaOCl from a tank or carboy without the use of pumps.
