Proportional mixers are used to properly mix concentrates with water producing working solutions and make-up solutions.  Typical applications for proportional mixing pumps are coolants, cleaners, strippers, degreasers, and fertilizers.
Advantages of using proportional mixers are:
Save labor by mixing faster than by hand
Automatic models save even more by keeping containers full unattended
More accurate than hand mixing
Safer because less contact with concentrates
Lean coolant mixtures can cause excessive tool wear, corrosion on parts and machines, and increased bacteria growth
Rich coolant mixtures can cause sticky or slippery residues, operator irritation, and waste expensive concentrate
Lean cleaner mixtures won't perform as intended
Venturi types
use water passing over an orifice to create suction that draws the concentrate from the container and mixes it with the water.
Concentration is controlled by changing orifice size.
Accuracy can be affected by both water pressure and concentrate level.
CAUTION:
These units cannot operate with any back pressure, so they can only be used to fill a pail or nearby container.
The outlet hose cannot be restricted or used to shut off the mixer.
The outlet hose must NOT be connected to any device that can restrict the flow.
This means NO sprayer devices, in-line systems, or piping overhead lines.
Note:
Plumbing codes in some areas may require a back flow preventer or other types of controls before the mixing system.  Also, it is always recommended (and required for the warranty) to install a screen filter before the mixer.
