Mazzei - 1584 Series - 1.5" Male NPT Inlet/Outlet Connections (0.50" Barbed/Male NPT Threaded Suction Port Cap)
1584 Series Venturi Injector with 1.5" NPT Connections
Differential pressure injector with internal mixing vanes for precise chemical and air injection. 1.5" male NPT inlet/outlet, 0.50" suction port. No moving parts, maximum efficiency.
Venturi principle creates vacuum for precise chemical dosing
Venturi Vacuum Generation
Pressurized water constricts through the injection chamber, creating high-velocity jet stream. Increased velocity drops absolute pressure, generating vacuum at the 0.50" suction port that draws in chemicals or gases without pumps.
Internal Mixing Vanes
Patented vanes create thousands of microbubbles, maximizing surface area contact between gas and liquid. Multiple small bubbles dissolve faster than one large bubble of equal volume, improving injection efficiency.
No Moving Parts
Zero mechanical components means no maintenance cycles, no wear parts, no failure points. Polypropylene body resists most acids and alkalis while maintaining structural integrity under pressure.
Low Pressure Differential
Operates across wide pressure range with minimal pressure loss inlet to outlet. Requires only small differential to initiate vacuum, maintaining system efficiency while delivering consistent suction capacity.
Mazzei 1584 Series Connection Details
| Model Series | 1584 |
| Inlet Connection | 1.5" Male NPT (1.900" actual diameter) |
| Outlet Connection | 1.5" Male NPT (1.900" actual diameter) |
| Suction Port | 0.50" Barbed/Male NPT Threaded Cap |
| Body Material | Polypropylene (PP) |
| Design Type | Differential Pressure Venturi with Internal Mixing Vanes |
| Compatible Additives | Liquids and gases (air, oxygen, ozone, chemical solutions) |
Available body materials for chemical compatibility
The Mazzei 1584 series is available in multiple materials depending on chemical resistance requirements. Standard polypropylene (PP) offers versatility and cost-effectiveness with high tensile strength and resistance to most acids and alkalis. PVDF upgrades provide superior temperature and pressure handling, ozone resistance, UV stability, and NSF 61/FDA approval when specified in natural (undyed) form. ECTFE material excels in alkaline environments above pH 10 with extreme chemical resistance and low flammability per DIN 4102.
Understanding 1584 model designations
Mazzei 1584 series injectors use suffix letters to denote performance and connection variations. The "X" suffix indicates liquid-only optimization with higher suction rates at lower outlet pressures. The "A" and "C" suffixes designate different connection size configurations on the same body. Verify your specific model number (1584A, 1584C, 1584X, etc.) against your system's inlet/outlet threading and suction port requirements before ordering.
No Maintenance
Zero moving parts eliminates rebuild kits, seals, and scheduled service intervals
Lower Operating Cost
More efficient than pump-fed systems with no power consumption at injection point
Precise Dosing
Consistent vacuum generation delivers repeatable chemical injection rates under stable inlet pressure
Thorough Mixing
Internal vanes create complete dispersion before outlet, no downstream mixing chambers required
