Venturi Injectors

DEMA has the ideal inline chemical injector to inject fluids or air into lines conveying water and other liquid under pressure. Injectors have no moving parts, nothing to wear out or lubricate, resulting in extremely low maintenance. They are compact, needing no foundation or mounting bracket, and can be installed in any position. Injectors require no wiring, are self-priming and need no bleeding or filling. Injection rate is simple to set and can be quickly adjusted during operation and there is nothing to drain for seasonal shut down.
