Mazzei - 484 Series - 0.50" Male NPT Inlet/Outlet Connections
484 Series with 0.50" Male NPT Inlet/Outlet Connections
Differential pressure injector with internal mixing vanes for chemical and gas injection in water treatment systems. No moving parts, maximum efficiency.
Venturi differential pressure creates vacuum suction for precise chemical dosing
Venturi Vacuum Generation
Pressurized water is constricted into a high-velocity jet stream through the injection chamber. The velocity increase drops absolute pressure below atmospheric, creating vacuum at the suction port without pumps or moving parts.
Internal Mixing Vanes
Patented vane design creates thousands of microbubbles during injection. Multiple small bubbles have exponentially more surface area than one large bubble of the same volume, dramatically improving solubility and contact efficiency.
Zero Moving Parts
The Mazzei 484 Series has no pumps, impellers, or mechanical components. Injection happens purely through fluid dynamics. This means no maintenance cycles, no seal replacements, and decades of reliable operation.
Minimal Pressure Drop
Requires only a small pressure differential between inlet and outlet to initiate vacuum. Operates over a wide range of system pressures with lower operating costs than traditional chemical feed pumps.
PVDF construction for chemical resistance and UV stability
This injector is manufactured from polyvinylidene fluoride, an advanced thermoplastic superior to PVC, polypropylene, and polyethylene. PVDF handles higher pressures and temperatures, resists ozone, sulfuric acid, nitric acid, and chlorine exposure. It offers better abrasion resistance and is UV-stable for outdoor installations. Available in natural PVDF (NSF 61 and FDA approved) or dyed PVDF for visibility in complex systems.
Mazzei 484 Series injector dimensions and connections
| Model Series | Mazzei 484 |
| Inlet Connection | 0.50" Male NPT (1/2" NPT) |
| Outlet Connection | 0.50" Male NPT (1/2" NPT) |
| Suction Port | 0.25" Barbed with Cap |
| Material | PVDF (Polyvinylidene Fluoride) |
| Certifications | NSF 61, FDA Approved (Natural PVDF) |
| Typical Applications | Chemical injection, air injection, ozone injection, gas dissolution |
Works with reverse osmosis systems, irrigation lines, and water treatment installations
The Mazzei 484 Series injector with 0.50" male NPT connections integrates into any water system requiring chemical or gas injection. Common applications include chlorine dosing for disinfection, hydrogen peroxide injection for oxidation, ozone dissolution for advanced oxidation processes, fertilizer injection in irrigation systems, pH adjustment chemical dosing, and air injection for iron and manganese oxidation. The 1/2" NPT threads are standard across commercial and residential water treatment. Suitable for municipal water treatment, aquaculture, hydroponics, industrial process water, and reverse osmosis pre-treatment or post-treatment stages.
Precision Dosing
Vacuum suction rate is proportional to flow, providing consistent chemical ratios across varying system demands
Lower Operating Cost
No electricity required, no pump maintenance, no consumable parts to replace over the injector lifespan
Chemical Resistant
PVDF material resists acids, alkalis, chlorine, ozone, and UV exposure for outdoor installation
Instant Mixing
Microbubble generation and internal vanes provide complete mixing at the point of injection
