Mazzei - ISO 1583 Series - 40mm Male BSPT Inlet/Outlet Connections (0.50" Barbed/Male NPT Threaded Suction Port Cap)
ISO 1583 Series 40mm BSPT Chemical Injection System
Precision venturi injector with internal mixing vanes for differential pressure chemical dosing in commercial water treatment applications
The Mazzei 1583 Series venturi injector uses differential pressure to create vacuum suction at the 0.50" port, drawing chemicals or gases into the water stream through internal mixing vanes that generate thousands of microbubbles. Operates with 40mm Male BSPT inlet/outlet connections and available in polypropylene, PVDF, or ECTFE materials depending on chemical compatibility requirements.
Venturi Injection Technology
Venturi Design
Pressurized water constricts through injection chamber, creating high-velocity jet stream that generates vacuum at suction port without external power
Microbubble Mixing
Internal mixing vanes create thousands of microbubbles, dramatically increasing surface area for superior gas dissolution and chemical distribution
Zero Moving Parts
No pumps, motors, or mechanical components to maintain or replace, reducing operating costs and eliminating common failure points
Wide Operating Range
Functions across broad pressure spectrum with minimal differential required between inlet and outlet to initiate suction vacuum
40mm BSPT Connections
British Standard Pipe Thread male inlet and outlet fittings with 0.50" barbed or Male NPT threaded suction port cap configuration
Material Options
Choose polypropylene for acids and alkalis, PVDF for ozone and higher temperatures, or ECTFE for extreme alkaline environments above pH 10
Chemical Resistance Profiles
System Integration
The 1583 Series integrates into commercial water treatment systems requiring precise chemical injection including chlorine dosing, pH adjustment, fertilizer injection for agriculture, ozone dissolution, and oxygen enrichment. Compatible with Mazzei chemical and air injection assemblies. Note that BSPT threads measure larger than their nominal size—a 40mm BSPT thread does not measure 40mm on a ruler. The 0.5" Male NPT PVDF injectors are interchangeable with 15mm Male BSPT PVDF injectors due to identical thread pitch. Select material based on chemical compatibility: polypropylene for general use, PVDF for oxidizers and elevated temperatures, ECTFE for high-pH alkaline applications.
Mazzei venturi injectors have been engineered for commercial water treatment since their patented design set the standard for differential pressure injection without mechanical components.
