ProMix PD2K Proportioners

ProMix PD2K Proportioners 

Positive Displacement Proportioning System

100% Positive Displacement Technology for accurate mix ratios and consistent performance

The ProMix PD2K mixes the material close to the gun so the flush zone is significantly smaller. This allows customers to use less paint, spend less on disposal costs and allows for faster color changes. And because there is limited mixed material in the system, the ProMix PD2K is ideal for short pot life materials. It is also compatible with acid-based materials.

Graco has specific ProMix proportioners that are designed to manage tough acid catalyst applications like cabinetry and bar counter tops. The corrosion resistance fluid section, plus the smart fluid plate with 316 and 17-4 SST catalyst sections, can easily handle strong acid catalysts.

Features :

  • Up to 80% reduction in flushing waste over the most efficient traditional proportioning systems
  • Limited mixed material in the system – great for short pot life materials
  • Faster color changes and less material to flush mean less waste and less downtime
  • Stalls under pressure for consistent, on-ratio results (within 1% accuracy)
  • Proportion both epoxy and urethane with ONE system
  • Manage up to 30 colors and 4 catalysts with 2 or 4 dosing pumps
  • Field serviceable in less than 20 minutes – no need for costly factory rebuilds like gear pumps
