Well suited for rotor blade production

The Graco VRM Metering System is a hydraulic variable metering system that uses positive displacement pumps to dispense resin materials. Because of its high flow rates, this system is a technology breakthrough, especially for wind blade manufacturers who are required to dispense large volumes of material to keep up with production demands.

  • High flow rates – up to 66 lb (30 kg) per minute @ 70°F (21°C)
  • Ratio accuracies better than +/- 2%
  • Variable ratio allows you to change ratios on the fly
  • Ratio range: 1:1 to 5:1
  • Intuitive, easy-to-use controls simplify training
  • Integrated USB lets you download process data onto a flash drive for further analysis
