Drum Mount Mixing Station

Model # 985500

The Drum Mount Mixing Station is a drum-mounted chemical proportioner for accurately diluting chemical concentrates to required ratios and filling any sized container with diluted, ready-to-use chemical solutions. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate directly from the drum into the water stream to create an accurately diluted solution. Ball valve activation allows for hands-free dispensing.
