Mazzei - 784 Series - 0.75" Male NPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
Mazzei 784 Series Venturi Injector
Differential pressure injector with 0.75" NPT connections and internal mixing vanes for efficient chemical or gas injection into water streams
Venturi Principle with Precision Engineering
Venturi Vacuum Generation
Pressurized water is constricted into a high-velocity jet stream through the injection chamber, creating a vacuum that draws additives through the suction port without any pumps or moving parts
Internal Mixing Vanes
Patented internal vanes create thousands of microbubbles, drastically increasing surface area contact between gases and liquids for superior solubility and mixing efficiency
Minimal Pressure Loss
Operates over a wide pressure range and requires only minimal differential between inlet and outlet to initiate vacuum at the suction port, preserving system efficiency
Zero Maintenance Design
No moving parts means no wear components to replace, no seals to fail, and dramatically lower operating costs compared to mechanical injection systems
Mazzei 784 Series Connection Details
| Inlet Connection | 0.75" Male NPT (1.050" actual diameter) |
| Outlet Connection | 0.75" Male NPT (1.050" actual diameter) |
| Suction Port | 0.25" Barbed with Cap |
| Injector Type | Differential Pressure Venturi |
| Material Options | Polypropylene (PP), PVDF, ECTFE |
| Series Variations | X (liquids only), A/C (connection differences) |
Choose the Right Material for Your Application
Polypropylene (PP)
Cost-effective and versatile with high tensile strength. Highly resistant to most acids and alkalis. Lightweight, rigid, and suitable for general-purpose chemical injection applications
PVDF (Natural or Dyed)
Advanced thermoplastic superior to PVC and PP. Handles higher pressures and temperatures. Resistant to ozone, sulfuric and nitric acids, chlorine, and UV light. NSF 61 and FDA approved when using natural PVDF
ECTFE
High-performance material with extreme chemical resistance, especially in alkaline environments above pH 10. Low flammability, excellent weather and UV resistance, and safe for demanding tank and apparatus applications
System Integration
The Mazzei 784 Series injector fits 0.75" NPT threaded water lines and is compatible with chemical dosing systems, ozone generators, fertigation equipment, and air injection setups. Use with liquid additives, oxygen, ozone, air, or other gases. Consult Mazzei performance charts to select the appropriate series variation (X, A, C) based on your required suction rates and outlet pressure conditions.
Wide Application Range
Chemical dosing, ozone injection, fertigation, air injection, and more
Material Choices
PP, PVDF, and ECTFE options for chemical compatibility and temperature requirements
Patented Design
Maximized injector efficiency and mixing with proven Mazzei engineering
Low Operating Cost
