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

  • Sealants
  • Adhesives
  • Silicones
  • Epoxies
  • Acrylics
  • Urethanes
  • Inks
  • Mastics
  • Lubricants
  • Butyls
  • PVC sealers

Check-mate Pump


  1. Xtreme Coupler: Quick-disconnect coupler for easy maintenance
  2. Optional Enclosed Wet Cup: Prevents seal contamination and allows recirculation, and reduces maintenance and extends seal lif
  3. Cartridge Throat Packings: Allows for easy servicing without removing from ram
  4. Cast Outlet and Inlet Housing: Improves structural integrity
  5. Piston Valve with Floating Piston Seal: For maximum pressure balance over a range of material viscosities
  6. Hard Part Coatings: Standard Severe Duty coating on rods and cylinder maximizes wear life
  7. Replaceable Seat: Minimizes service cost
  8. Floating Priming Plate: Provides uniform balance and flow
