Six typical installations are shown below. Our engineering
staff can assist with product selection and application.

The injector is installed around a point of restriction such
as a regulator valve or a gate/ball valve to create a differential
pressure across the injector. This allows the injector to
produce a vacuum and draw in material.
(See Fig.1 and Fig.2)

Fig.3
The injector is installed on the mainline and the pressure
reducing device is on the bypass. Chemical injection
can be turned on when the control valve is closed. When
the valve is open, injection stops due to reduced pressure
differential. (See Fig.3)

Fig.4
The injector is installed on a bypass with a booster
pump. When mainline pressure cannot be reduced, a small
booster pump can be used to create sufficient differential
pressure to operate the injector. (See Fig.4)

Fig.5
The injector is installed in the mainline. The injector
must see a sufficient differential to operate. In other
words, the inlet pressure must be sufficiently greater
than the outlet pressure. (See Fig.5)
