CPVC Venturi Injector

A CPVC Venturi Injector is a device made from Chlorinated Polyvinyl Chloride (CPVC) that uses the Venturi principle to draw and mix liquids or gases into a flowing water stream. It works by creating a pressure difference when water passes through a narrowed section of the injector, which allows chemicals, fertilisers, or other solutions to be sucked into the main pipeline.CPVC Venturi injectors are commonly used in irrigation systems, water treatment plants, chemical dosing systems, and industrial applications because CPVC material provides excellent corrosion resistance, durability, and high temperature tolerance.

The CPVC Venturi Injector is a precision-engineered device designed to inject or dose liquids and gases into a main fluid stream using the Venturi principle. This injector is ideal for use in high-temperature and corrosive fluid systems. It operates based on pressure differential, creating a vacuum that draws the secondary fluid into the primary flow without the need for additional mechanical components. This makes it highly suitable for chemical dosing, disinfection, fertigation, and water treatment applications.
