Venturi Systems SA (PTY LTD) t/a Pumps Unlimited are importers and suppliers of MAZZEI ® VENTURI INJECTORS and AERATION products in South Africa
Mazzei® Venturi Injectors are high-efficiency differential pressure injectors with internal mixing vanes. Due to the efficiency of Mazzei® Venturi Injectors for liquid and air transfer into water, the injectors are the perfect low-energy, low maintenance, and low costs method for forcing air, liquid, gas, or oxygen into the water with a greater transfer.
Mazzei Airjection® Soil Aeration System
Mazzei AirJection® Soil Aeration Technology may significantly benefit plants with:
- Increased root mass and healthier plants
- Better quality fruit with higher sugar content
- Increased fruit density and crop yield
- Improved water use efficiency
- Increased plant salinity tolerance
- Reduced fertilizer application rates
- Earlier maturation in most crops
- Improved late season production
How do Mazzei® Venturi Injectors Work
The venturi injector creates a vacuum inside the differential pressure injector body with internal mixing vanes, which initiates suction through the suction port which can be used to inject and mix liquids or gasses into the motive stream. These long life Mazzei Venturi Injectors are trouble-free because of their one-piece construction (either chemically resistant PVDF Kynar, polypropylene, or stainless steel) design. The venturi injector gives constant injection which gives uniform distribution of chemicals or gasses, it is self-priming and can run dry air and the venturi injector is available with male NPT or BSPT thread connections.
The PVDF (Kynar, Hylar) thermoplastic venturi injector is extremely strong and resistant to most agricultural chemicals including Sulphuric Acid, Nitric Acid, Ozone and Chlorine. It is also more resistant to abrasive material such as gypsum.
