High Volume 1242 Mixing Station

Model # 985845

The High Volume 1242 Mixing Station is a 12 GPM @ 40 PSI chemical proportioner for accurately diluting a chemical concentrate to the required ratio and for rapidly filling large containers with diluted, ready-to-use chemical solution. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted solution. Ball valve activation allows for hands-free dispensing.
