Mazzei - 287 Series - 0.50" Male NPT Inlet/Outlet Connections (0.25" Barbed Suction Port Cap)
0.50" NPT Inlet/Outlet with 0.25" Barbed Suction Port
Venturi Injection Process
Pressurized Water Entry
Water enters through the 0.50" NPT inlet and is constricted toward the injection chamber, converting pressure into a high-velocity jet stream
Suction Generation
Increased velocity through the chamber creates negative absolute pressure at the 0.25" barbed suction port, drawing liquid or gas additives into the stream
Microbubble Formation
Internal mixing vanes create thousands of microbubbles, dramatically increasing surface area for superior gas-to-liquid contact and solubility
Flow Restoration
Jet stream diffuses toward the 0.50" NPT outlet, velocity reduces, and thoroughly mixed solution exits with minimal pressure loss
PVDF Construction Benefits
This Mazzei 287 series injector is constructed from polyvinylidene fluoride, an advanced thermoplastic superior to PVC, polypropylene, and polyethylene. PVDF handles higher pressures and temperatures, resists ozone, sulfuric and nitric acids, chlorine, and UV exposure. The material meets NSF 61 and FDA approval standards when natural PVDF is specified. No moving parts means simplified maintenance and significantly lower operating costs compared to mechanical injection systems.
Application Range
The Mazzei 287-NPVDF operates effectively across a wide pressure range, requiring only minimal differential pressure between inlet and outlet to initiate suction. Suitable for injecting air, oxygen, ozone, chlorine, acids, alkalis, and other treatment chemicals in municipal water systems, aquaculture, industrial process water, irrigation, and pool/spa applications. The 0.50" NPT threaded connections accommodate standard plumbing fittings, while the 0.25" barbed suction port cap accepts flexible tubing for chemical feed lines.
