Mazzei - 584 Series - 0.75" Male NPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
0.75" NPT Venturi Injector with Internal Mixing Vanes
Differential pressure injector for chemical and gas dosing with patented internal mixing technology. PVDF construction for superior chemical resistance and durability.
Patented venturi design creates maximum vacuum with minimal pressure loss
High-Velocity Injection
Water constricts through the injection chamber, creating a high-velocity jet stream that generates vacuum at the suction port. Draws chemicals or gases without external power.
Internal Mixing Vanes
Patented vane design creates thousands of microbubbles, dramatically increasing surface area for gas-to-liquid contact. Greater surface area means faster, more complete solubility.
Zero Moving Parts
Entirely passive operation with no pumps, motors, or mechanical components. Simplified maintenance, longer service life, and significantly lower operating costs.
PVDF Chemical Resistance
Polyvinylidene fluoride construction handles acids, chlorine, ozone, and high temperatures. Superior to PVC and polypropylene with NSF 61 and FDA approval available.
Wide Operating Range
Functions across a broad pressure spectrum with minimal differential required. Consistent vacuum generation and mixing performance under varying system conditions.
Mazzei 584 Series Technical Details
| Model Series | Mazzei 584 Series |
| Inlet Connection | 0.75" Male NPT |
| Outlet Connection | 0.75" Male NPT |
| Suction Port | 0.25" Barbed with Cap |
| Material | PVDF (Polyvinylidene Fluoride) |
| Approvals | NSF 61, FDA (Natural PVDF) |
| UV Resistance | Yes, UV-A and UV-B stable |
Why PVDF outperforms standard plastics
Polyvinylidene fluoride is an advanced thermoplastic engineered for demanding chemical injection applications. It resists ozone degradation, handles sulfuric and nitric acids without deterioration, and maintains structural integrity at higher temperatures than PVC or polypropylene. PVDF exhibits superior abrasion resistance for longer service life and remains stable under continuous UV exposure. The material is physiologically safe and meets NSF 61 drinking water standards when natural (undyed) grade is specified. This makes the Mazzei 584-NPVDF series suitable for potable water treatment, industrial process water, aquaculture oxygenation, and chemical dosing in harsh environments.
Common uses for the 0.75" Mazzei injector
Chemical Dosing
Inject chlorine, hydrogen peroxide, fertilizers, or scale inhibitors into water systems without pumps. Precision dosing proportional to flow rate.
Ozone Injection
Introduce ozone gas for disinfection and oxidation. Microbubble generation improves ozone dissolution and contact efficiency.
Oxygen Transfer
Aerate ponds, aquaculture systems, or wastewater treatment. Increases dissolved oxygen faster than surface aerators or diffusers.
Fertilizer Injection
Agricultural and greenhouse irrigation systems. Draw liquid fertilizers into irrigation lines with no electrical power required.
Engineered Precision
Mazzei's patented venturi geometry maximizes suction capacity and mixing efficiency across all operating pressures
Lower Operating Costs
No electricity, no pumps, no maintenance schedules. Passive operation saves energy and reduces total cost of ownership
Instant Mixing
Internal vanes create thorough mixing within the injector body. No additional mixing chambers or downstream contact time required
NSF Certified
Natural PVDF grade meets NSF 61 drinking water standards. Safe for potable water treatment and food-grade applications
