Graco HFR Hydraulic Fixed Ratio High Volume Dispensing System

About the Graco HFR Hydraulic Fixed Ratio Two-Part Meter Mix System

Graco HFR™ Hydraulic Fixed Ratio Metering System is an industrial metering, mixing, and dispensing system processes 2K adhesives, urethanes, polysulfides, epoxies, silicones, and resins with continuous flow bead dispensing at a precise 1:1 ratio. Built for batch processing, potting, encapsulating, vacuum infusion, pultrusion, and automated applications, the HFR delivers a smooth, on-ratio dispense, reducing waste and increasing production efficiency. With a lower total cost of ownership, its modular design offers flexibility while using reliable, durable Z-Pumps for handling abrasive sealants and adhesives.

Graco HFR System Features and Benefits

• Fixed 1:1 Ratio: Ensures precise material mixing and dispensing.
  
• Consistent Flow & Accuracy: Automatically adjusts material flow and pressure for an even, high-quality bead.
  
• Lower Cost than Shot Meters: Advanced technology at a fraction of the cost of traditional systems.
  
• Modular & Configurable: Customize to meet your material needs, with faster lead times than custom solutions.
  
• Advanced Display Module (ADM): Stores up to 100 shot sizes and provides data tracking via USB.
  
• Reliable & Easy Maintenance: Standardized parts simplify maintenance and eliminate costly pump rebuilds.
  
• Precision Motor Control: Ensures smooth dispensing with closed-loop pressure and flow monitoring.
  
• High Viscosity Capability: Handles demanding materials with constant pressure or flow rate options.
