Graco Merkur 23:1 – Air-Assisted Airless Complete Unit with Bellows Pump

The Graco Merkur 23:1 Airless complete unit is an industrial, air-assisted coating system featuring advanced bellows pump technology. It has been specifically developed for demanding applications where reliable material delivery, high pressure stability and reduced maintenance are essential.

The innovative bellows design replaces conventional throat packings, minimizing the risk of leakage and material contamination. This makes the system particularly suitable for UV-curable, water-based or sensitive coating materials.

  • 23:1 ratio – powerful pressure amplification
  • Bellows pump – no conventional throat packing required
  • U-cup seal – ideal for UV and moisture-sensitive materials
  • Stainless steel components – high chemical resistance
  • Reduced maintenance effort – fast cleaning & long service life
