Features & Advantage:
Commercial grade one with no moving parts.
Low cost, easy operation, stable fertilizer concentration, free extra power.
It works by suction and will draw liquid fertilizer out of almost any container your provide.
Realize fertilizing in proportion to maintain a constant nutrient concentration.
Realize the integration of irrigation and fertilization and save fertilizer and manpower.
Built-in check valve to prevent the injection liquid backflow.
Can be plumbed on a bypass for less restriction(the preferred method),or directly into a main water line.
Application:
It is very efficient for small and medium-sized irrigation areas to apply water and fertilizer.
If in doubt always choose a smaller size,put it on a bypass assembly which allows you to adjust the flow through the venturi injector and does not
restrict the flow as much.
How it works
Use three-way, elbow and other parts to connect Venturi fertilizer injector in parallel to the main valve of the main waterway. Turn down the waterway main valve when working, it will form a differential pressure which makes the water flow through the branch of Venturi injector. The Venturi tube is a kind of converging passage that gradually widens (see diagram). When the water flow through the narrow Venturi pipe's throat, the flow rate could become increased and the pressure could become decreased. When there is a smaller diameter pipe accordingly equipped in the Venturi tube's throat, the created negative pressure would draw the liquid fertilizer into the pipe system to fertilize from the exposed fertilizer bucket. The switch valve at the entrance can adjust the proportion of the intake of water and fertilizer.
