Graco Piston Pump Drum Unloading Systems

Graco’s SaniForce drum unloaders can evacuate medium to high viscosity products from their original 55 gallon containers in less than 5 minutes, without diluting the material. The modular design of the Graco systems allow a great amount of flexibility when building a system. Graco’s options allow you to configure you own system. Options include:

• Stainless steel or epoxy coated carbon steel frames
• Stainless steel enclosed or open controls
• A choice of 3 different piston pumps or 2 different diaphragm pumps

Product Features:

  • Inflatable wiper seals for increased efficiency and faster change-out of containers
  • 99% evacuation rate
  • Sanitary flange clamps for quick disassembly
  • Liner guard to prevent bags from entering pump
  • One size follower plate and seal to accommodate straight-sided and tapered drums
