The Drum Mount Uni-Body HC Mixing Station is a "high concentrate" chemical proportioner that mounts into a drum's threaded bung hole for diluting chemical concentrates to strong ratios and filling any size container with ready-to-use chemical solution. This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw chemical concentrate directly into the water stream to create a very strong solution, using metering tips for accurate dilution ratios. Ball valve activation allows for hands-free dispensing. Available with several flow rates for various dispensing requirements.
