It may become necessary to replace a chemical injector during the long life of your Lafferty Mixing Station.
One common reason for changing injector bodies is to change the factory-set flow rate to a lower or higher flow based on operational experience.
For example, some water supplies cannot maintain the 4.5 GPM @ 40 PSI required for the high flow injector. In those cases, users would observe the pressure on the gauge dropping below 25 PSI during operation. Switching to a lower flow rate maintains the required pressure to create vacuum and draw chemical into the water stream.
Changing the injector body be accomplished with simple hand tools, as shown in this video tutorial.
Bottle Fill
0.62 GPM @ 40 PSI to avoid splashing while filling small hand-held spray bottles.
Dilution Range
142:1 to 1.7:1 @ 40 PSI
Low Flow
2.10 GPM @ 40 PSI for mid-size containers (1-gallon jugs, Pump Up Foamers, etc.)
Dilution Range
480:1 to 3.5:1 @ 40 PSI
High Flow
4.51 GPM @ 40 PSI for larger containers such as mop buckets and air pump foamers.
Dilution Range
1,031:1 to 4.8:1 @ 40 PSI
