GRACO Piston Pumps

Ideal For Medium

to High-viscosity Materials

  • Available as stand alone, with elevator or ram
  • Pressure ratio range: from 5:1 to 85:1
  • Minimizes left-over materials and reduces waste
  • High quality, durable parts
  • Tracks material usage and flow
  • Max. life option available for abrasive materials and prolonged life

System Features And Benefits

  • Available in Carbon Steel and Stainless Steel models; SST models for waterborne compatibility
  • Large internal porting for maximum flow
  • Floating piston seal and priming plate improve balance and performance
  • Maintains balance over a wide viscosity range
  • Minimal bead distortion for critical dispensing of expensive materials
  • High flow and pressures increase production
  • High output per cycle reduces wear for longer life and lower repair costs

Typical Applications

  • Feeding high volume applicators, multiple meters or proportioners
  • Transferring sealants or adhesives to one or more operator dispensing stations
  • Packaging drums, pails, caulking tubes or chubs

Typical Fluids Handled
