Venturi injectors

Injectors from Mazzei are high-quality injectors that inject liquid into a flow on the basis of a pressure difference (venturi principle).
When a continuous liquid steam enters the injector under pressure, it passes at high speed through a small opening into the injection chamber. The increase in speed creates a vacuum so that the liquid to be admixed is drawn in.



  • High efficiency (20% pressure loss on starting)
  • No electrical power supply required
  • Low maintenance: No moving parts
  • Made from high-quality thermoplastics (PP and PVDF)
  • Significant cost savings compared with other injection methods
  • Safe to use for injection of common chemical agents under vacuum


Injection of liquid or gas into irrigation, insecticide, washing and/or swimming pool systems
