The Venturi ALFA injectors are extensively used for the application of liquid fertilisers and agricultural chemicals into a pressurised irrigation system. The chemically resistant materials of construction makes them ideal for most agricultural chemicals including acids and liquid chlorine. They can also be safely used in many industrial applications.
The injectors use the Venturi tube principle, they have no moving parts and therefore they are virtually maintenance free. They do not require any source of energy, they utilise a minimal amount of differential pressure ( P) between the inlet and outlet sides, whilst the flow rate of the injected fluid varies according to each model and the inlet pressure/flow rate.
