Mazzei - ISO 978 Series - 25mm Male BSPT Inlet/Outlet Connections (0.50” Barbed/Male NPT Threaded Suction Port Cap)
ISO 978 Series Key Specs
Operating Principle & Materials
| Operation Method | Pressurized water creates high-velocity jet stream through constricted injection chamber, generating vacuum at suction port to draw and mix additives |
| Vacuum Generation | Minimal pressure differential required between inlet and outlet to initiate suction |
| Mixing Technology | Internal vanes create thousands of microbubbles with greatly increased surface area for superior gas dissolution (air, oxygen, ozone) |
| GRPP (Green Polypropylene) | Highly resistant to acids and alkalis, high tensile strength, lightweight and cost-effective |
| PVDF (Blue Polyvinylidene Fluoride) | Higher pressure/temperature capability, ozone resistant, UV resistant, NSF 61 and FDA approved (Natural PVDF) |
| ECTFE (Ethylene Chlorotrifluoroethylene) | Excellent alkaline resistance above pH 10, extreme chemical resistance, physiologically safe, low flammability per DIN 4102 |
| BSPT Connection Note | 25mm BSPT measures approximately 1.041" actual diameter on ruler, not 25mm. 0.5" Male NPT PVDF threads are interchangeable with 15mm Male BSPT PVDF |
Water Treatment System Integration
The Mazzei ISO 978 Series venturi injector integrates into pressurized water lines for chemical dosing, ozone injection, oxygen enrichment, and gas dissolution applications in municipal water treatment, aquaculture, industrial process water, and irrigation systems. The 25mm male BSPT connections accommodate international plumbing standards, while the 0.50" suction port accepts barbed tubing or male NPT threaded fittings for flexible chemical feed integration. Material selection depends on chemical compatibility and operating conditions: GRPP for general acids and alkalis, PVDF for higher pressures and ozone environments, and ECTFE for extreme alkaline conditions above pH 10. The differential pressure design operates efficiently across a wide pressure range without external power or moving parts.
