Mazzei - ISO 283 Series - 15mm Male BSPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
ISO 283 Series Venturi Injector with 15mm Male BSPT Connections
The Mazzei ISO 283 Series injector uses a venturi effect to generate vacuum at the suction port, drawing liquid or gas additives into the pressurized water stream without pumps or motors. Inlet and outlet connections are 15mm Male BSPT, with a 0.25 inch barbed suction port for chemical or air introduction. The patented internal mixing vanes create microbubbles that maximize contact surface area and solubility for ozone, oxygen, fertilizers, and other additives.
How the Mazzei Venturi Injector Works
Venturi Vacuum Generation
Pressurized water enters the injector inlet and is constricted into a high-velocity jet stream. The increase in velocity decreases absolute pressure, creating a vacuum at the suction port that draws in additives.
Internal Mixing Vanes
Patented vanes create thousands of microbubbles, dramatically increasing the surface area of gas in contact with liquid. Multiple microbubbles have far greater surface area than one large bubble of the same volume.
No Moving Parts
Eliminates mechanical wear, simplifies maintenance, and reduces operating costs compared to pump-driven injection systems. The injector operates continuously with minimal pressure differential required.
Wide Operating Range
Functions across a broad spectrum of inlet pressures and requires only minimal pressure differential between inlet and outlet to initiate suction. Adapts to varying flow conditions without adjustment.
Multiple Material Options
Available in polypropylene (GRPP), PVDF, and ECTFE to match chemical compatibility requirements. PVDF offers superior resistance to ozone, UV, acids, and chlorine with NSF 61 and FDA approval.
15mm Male BSPT Threads
BSPT threads measure larger than the nominal size on a ruler. 15mm BSPT threads are interchangeable with 0.5 inch Male NPT PVDF injectors, both sharing the same threads per inch.
Chemical Resistance and Construction
Polypropylene (GRPP)
Green colored, highly resistant to most acids and alkalis. Versatile, cost-effective, with high tensile strength. Lightweight and rigid construction suitable for most water treatment applications.
PVDF (Blue or Natural)
Advanced thermoplastic superior to PVC, PP, and polyethylene. Handles higher pressures and temperatures, resists ozone, sulfuric and nitric acids, chlorine, and UV. NSF 61 and FDA approved in natural form.
ECTFE
High-performance material with excellent alkaline resistance above pH 10. Extreme chemical resistance, low flammability per DIN 4102, UV-resistant, and physiologically safe for demanding tank and apparatus construction.
System Integration
The Mazzei ISO 283 Series injector is designed for inline installation in pressurized water systems requiring chemical dosing, ozone injection, fertilizer introduction, or air infusion. The 15mm Male BSPT inlet and outlet connections integrate with standard British pipe threading, common in international and commercial installations. The 0.25 inch barbed suction port accepts flexible tubing for connection to chemical reservoirs, ozone generators, or gas sources. Variations include X-series for liquids only with higher suction rates at lower outlet pressures, and A/C series with different connection sizes. Note that 15mm Male BSPT PVDF injectors are interchangeable with 0.5 inch Male NPT PVDF injectors due to identical thread pitch.
Mazzei venturi injectors have been the industry standard for differential pressure injection since their patented design introduced internal mixing vanes to maximize efficiency and solubility without mechanical complexity.
