The 2-Way High Volume Mixing Station is a 9.9 GPM @ 40 PSI chemical proportioner for accurately diluting 2 chemical concentrates to the required ratios and for quickly filling large containers with diluted, ready-to-use chemical solutions. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrates into the water streams to create accurately diluted solutions. Ball valve activation allows for hands-free dispensing.
