Mazzei - 878 Series - 1.0” Male NPT Inlet/Outlet Connections (0.50” Barbed/Male NPT Threaded Suction Port Cap)
1.0" NPT Chemical & Air Injection System
Three-Stage Venturi Action
Pressurized Water Constriction
Incoming pressurized water is constricted toward the injection chamber, transforming into a high-velocity jet stream that increases speed and drops absolute pressure.
Vacuum-Driven Chemical Draw
Velocity increase creates a powerful vacuum at the 0.50" suction port, drawing liquid or gas additives into the injection chamber where internal mixing vanes generate microbubbles.
Velocity Reduction & Mixing
The jet stream diffuses toward the outlet, reducing velocity and resuming normal flow with complete mixing and minimal pressure loss across the injector body.
Mazzei 878 Series Technical Details
| Model Series | Mazzei 878 |
| Inlet Connection | 1.0" Male NPT |
| Outlet Connection | 1.0" Male NPT |
| Suction Port | 0.50" Barbed/Male NPT Cap |
| Operating Principle | Differential pressure venturi |
| Moving Parts | None |
| Material Options | Polypropylene, PVDF, ECTFE |
Available Construction Options
Polypropylene (PP): Cost-effective and versatile with high tensile strength, resistant to most acids and alkalis. Lightweight, rigid construction ideal for general chemical dosing and air injection.
PVDF (Polyvinylidene Fluoride): Advanced thermoplastic with superior pressure and temperature handling. Resistant to ozone, sulfuric and nitric acids, chlorine, and UV light. NSF 61 and FDA approved when specified in natural (undyed) form.
ECTFE (Ethylene Chlorotrifluoroethylene): High-performance material with extreme chemical resistance in alkaline environments above pH 10. Low flammability, UV-resistant, and physiologically safe for demanding tank and apparatus applications.
System Integration
The Mazzei 878 Series with 1.0" Male NPT connections integrates into pressurized water lines for ozone injection, chlorination, fertigation, pH adjustment, and chemical dosing applications. Requires minimal differential pressure between inlet and outlet to initiate suction at the 0.50" port. Compatible with liquid and gas additives when paired with appropriate check valves and supply systems. Verify material compatibility with your specific chemical or gas before installation.
