Mazzei - ISO 4091 Series - 100mm Male BSPT Inlet/Outlet Connections (Dual 50mm Male BSPT Threaded Suction Ports)

The Mazzei ISO 4091 Series injector delivers precision chemical and gas injection through a 100mm BSPT venturi design with dual 50mm suction ports for high-capacity applications. Patented internal mixing vanes create thousands of microbubbles, maximizing contact surface area and solubility without moving parts or complex maintenance.

Mazzei ISO 4091 Series Technical Details

Model Series Mazzei ISO 4091
Inlet/Outlet Connection 100mm Male BSPT (British Standard Pipe Thread)
Suction Ports Dual 50mm Male BSPT Threaded
Injector Type Differential pressure venturi with internal mixing vanes
Material Options Polypropylene (GRPP), PVDF (Blue or Natural), ECTFE
Operating Principle High-velocity jet stream creates vacuum at suction port
Moving Parts None (maintenance-free design)
Applications Chemical injection, air/oxygen/ozone dissolution, water treatment
INSTALLATION & USE

Setup and Operation Guidelines

  1. Install the ISO 4091 injector inline with flow direction marked on the body, ensuring 100mm BSPT inlet receives pressurized water and outlet maintains minimal back pressure for optimal vacuum generation.
  2. Connect chemical or gas supply lines to either or both 50mm BSPT suction ports depending on application requirements, confirming all threaded connections are properly sealed with appropriate thread sealant rated for your additive.
  3. Verify minimum pressure differential between inlet and outlet (consult Mazzei performance charts for your flow rate) before introducing additives through the suction ports.
  4. Monitor suction performance during initial operation and adjust upstream pressure or downstream restrictions as needed to maintain consistent vacuum draw at the injection chamber.
COMPATIBILITY

Material Selection and System Integration

The ISO 4091 Series is available in three material options to match your chemical compatibility requirements. Polypropylene (GRPP) offers cost-effective resistance to most acids and alkalis with high tensile strength. PVDF provides superior temperature and pressure handling, ozone resistance, and UV stability for demanding applications, available in NSF 61 and FDA-approved Natural PVDF. ECTFE excels in high-alkaline environments above pH 10 with extreme chemical resistance and low flammability. Select material based on additive type, operating temperature, pressure range, and UV exposure. Note that BSPT thread sizing differs from nominal measurements—a 100mm BSPT measures larger than 100mm when checked with a ruler due to British Standard pipe thread conventions.

🔧 Pro Tip: Always measure pressure differential across the injector during commissioning rather than relying solely on inlet pressure. A restriction downstream (valve, filter, or elevation change) can kill vacuum suction even with adequate inlet pressure—the Mazzei needs that pressure drop to create the venturi effect.
