Mazzei - 1078 Series - 25mm Male BSPT Inlet/Outlet Connections (0.50” Barbed/Male NPT Threaded Suction Port Cap)
1078 Series - 25mm BSPT Injector with 0.50" Suction Port
Venturi Injection Process
Pressurized Water Inlet
Water enters through the 25mm male BSPT inlet and is constricted toward the injection chamber, accelerating into a high-velocity jet stream that reduces absolute pressure.
Suction Port Draws Additive
The increase in velocity creates a vacuum at the 0.50" barbed suction port, drawing liquid or gaseous additives into the injection chamber without external pumps.
Internal Vane Microbubbles
Patented internal mixing vanes create thousands of microbubbles as the additive mixes with water, drastically increasing surface area for gas-to-liquid contact and solubility.
Outlet Flow Resumes
The jet stream diffuses toward the 25mm male BSPT outlet, reducing velocity and resuming normal flow in a thoroughly mixed state with minimal pressure loss.
Polypropylene or PVDF Construction
The Mazzei 1078 series is available in green polypropylene (GRPP) for versatile, cost-effective chemical resistance to most acids and alkalis, or blue PVDF for advanced applications requiring higher pressure and temperature handling, ozone resistance, and superior resistance to sulfuric acid, nitric acid, and chlorine. PVDF offers better abrasion resistance and UV stability than polypropylene, PVC, or polyethylene. Natural PVDF is NSF 61 and FDA approved. ECTFE variants provide extreme alkaline resistance above pH 10 for demanding tank and apparatus construction.
Connection Details
Inlet and outlet connections are 25mm male BSPT (British Standard Pipe Thread). Note that BSPT sizing does not match ruler measurements—25mm BSPT measures approximately 1.041 inches in actual diameter. The suction port cap is 0.50 inch barbed or male NPT threaded. The 1078 series operates over a wide pressure range and requires only minimal pressure differential between inlet and outlet to initiate vacuum suction. Model variations include X (liquid-only, higher suction rates at lower outlet pressure), A (connection size difference), and C (connection size difference). Consult Mazzei specifications for flow rates, pressure requirements, and chemical compatibility with your specific application.
Applications and System Integration
The Mazzei 1078 series with 25mm BSPT connections integrates into reverse osmosis systems, irrigation installations, water treatment plants, and industrial process lines for injecting chlorine, ozone, hydrogen peroxide, acids, alkalis, fertilizers, and other liquid or gaseous additives. Use polypropylene models (1078-02-PP, 1078-03-PP) for general chemical dosing and PVDF models (1078-PVDF, 1078-NPVDF) for aggressive chemicals, high temperatures, or ozone applications. Ensure inlet pressure and flow rates meet Mazzei specifications for your desired suction capacity, and verify thread compatibility—0.5 inch male NPT PVDF injectors are interchangeable with 15mm male BSPT PVDF injectors due to identical thread pitch.
