Graco’s ProMix PD2K positive displacement proportioner mixes the material close to the gun so the flush zone is smaller, reducing solvent use and mixed material waste when compared with traditional proportioners. With limited mixed material in the system, it is well-suited for short-pot-life materials and also is compatible with acid-based materials.

According to the company, the ProMix PD2K offers 100-percent positive displacement technology that produces mix ratios of within 1 percent accuracy and more consistent pump performance. It can manage as many as 30 colors and four catalysts with the use of two or four dosing pumps. The proportioner also enables customers to proportion both epoxy and urethane using one system, rather than using multiple units to achieve the same result.

Unlike gear pumps, the ProMix PD2K features positive displacement precision dosing pumps that do not require factory rebuilds and can be serviced in the field in less than 20 min., Graco says.
