These devices inject chemicals or soap downstream from the high pressure pump. Using a Venturi effect, the injectors inject the chemical at either a fixed or adjustable rate. Various sizes are available to provide the correct size for the specific application.

This downstream chemical injector is designed to add chemicals downstream from the pump.  In order to operate, a pressure drop must occur across the injector, which draws chemical into the water stream.  Once the pressure drop is established, the amount of chemical injection is fixed.
