Mazzei - ISO 684 Series - 20mm Male BSPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
Mazzei ISO 684 Technical Details
| Model | Mazzei ISO 684 Series |
| Inlet/Outlet Connections | 20mm Male BSPT (British Standard Pipe Thread) |
| Suction Port | 0.25" Barbed Cap |
| Material | PVDF (Polyvinylidene Fluoride) - NSF 61 and FDA approved |
| Operating Principle | Differential pressure venturi with internal mixing vanes |
| Chemical Resistance | Ozone, sulfuric acid, nitric acid, chlorine |
| UV Resistance | Sunlight resistant, suitable for outdoor applications |
| Moving Parts | None (simplified maintenance) |
How to Install the Mazzei 684 Injector
- Thread the 20mm male BSPT inlet connection into your pressurized water supply line using appropriate thread sealant rated for your chemical application.
- Connect the outlet side to your downstream piping, ensuring a minimal pressure differential exists between inlet and outlet to initiate vacuum at the suction port.
- Attach your chemical or gas supply line to the 0.25" barbed suction port cap, ensuring a secure seal to prevent air leaks.
- Pressurize the system and verify vacuum creation at the suction port before introducing chemicals or gases into the water stream.
- Monitor injection rates and adjust inlet pressure as needed to achieve desired chemical dosing or gas dissolution levels.
Material Compatibility & Threading Standards
The PVDF construction of the Mazzei 684 injector makes it compatible with aggressive oxidizers including ozone, chlorine, hydrogen peroxide, and strong acids. PVDF offers superior performance over polypropylene, PVC, and polyethylene in high-temperature and high-pressure applications while maintaining resistance to UV degradation. The 20mm male BSPT threading follows British Standard Pipe Thread specifications, which measure larger than nominal size when measured with a ruler (approximately 0.825" actual diameter for this fitting). This injector is designed for liquid chemical injection and gas dissolution applications in water treatment, aquaculture, agriculture, and industrial process systems requiring precise additive mixing.
