The 7G injectors are pumps for pumping and mixing various media. The basic principle is simple: a gaseous media is used for the actuator; this media escapes at high pressure and high speed from a nozzle. During this process the media from the surrounding area is also drawn along and can be supplied to the downstream production process. Due to their design, the injectors do not need moving parts, as a result they have very low wear and are robust.
