The Graco PR70 contains all the key features you require in a compact, modular design, for:

  • Medium to low viscosity materials
  • Exceptional performance with materials form 1:1 to 24:1
  • MD2 valve high pressure accuracy with multiple seat styles and adjustable snuffback for clean, precise dispensing
  • Linear transducer monitors piston velocity to provide ratio assurance, and reduce scrap and re-work
  • Proven ratio accuracy. Positive-displacement and multiple tube sizes to pinpoint specific target ratios delivering ratio accuracy to +/- 1%

Other benefits of the PR70 include:

  • Stainless steel design reduces the chance of a material incompatibility
  • Long-lasting wear parts mean lower cost of ownership
  • Shaft seals designed for extended life and easy replacement
  • Preventive maintenance counter to plan system rebuilds around your production schedule
  • Linear thrust bearings eliminate side loading to maximize seal life and performance
