  • Reliable Flow - A 3 inch (76.2 mm) differential air motor and the double-acting pump design provides reliable fluid flow and accurate dispense.
  • Durable - Thick cast aluminum air motor housing offers unmatched durability.
  • Fewer Repairs - Fewer moving parts in the air motor assembly means less downtime and low repair cost.
  • Extended Seal Life - In-line pump design aligns the air motor piston and fluid piston rods to maximize seal life.
  • Reduce Downtime - Displacement rods have minimal wear due to a proprietary Graco manufacturing process.
  • Superior Sealing - Non-metallic poppet valves offer positive sealing performance, even with contaminated "dirty" air environments for long life without repair.
  • Reduced Icing - Large air porting design provides efficient use of compressed air supply for continuous pump operation and reduced icing.
  • Corrosion-Resistant - Corrosion-resistant design utilizes liquid salt nitriding, nickel plating, stainless steel, aluminum and chrome on key components for longer life.
