Electric Fixed Ratio (EFR) Metering System

The Graco Electric Fixed Ratio (EFR) is an electrically driven proportioner for two component sealant and adhesives. The EFR provides advanced material control in applications requiring consistent shots and beads.

Ideal for Bonding, Sealing, Gasketing and Potting

Electric Fixed Ratio (EFR)

MD2 Valve

  • Adjustable snuff back
  • Mixing at tip of the gun to limit purge material waste
  • Available in 1:1 to 10:1 for wide ratio, manual or robotic applications
  • With wear-resistant seals and surfaces, MD2 Valves with Elite construction last at least 10 times longer than regular valves.* 

*Data verified when pumping representative thermal interface material (TIM) in Graco test environment.

Choose Elite construction for applications of highly abrasive thermal interface materials (TIMs), silicones, urethanes, and epoxies. When your system configuration includes pumps and valves with Elite construction, you can expect to…

  • dispense at least 50,000 gallons (200,000 liters) before noticing any wear on pump pistons and cylinders*
  • get at least 10 times more equipment life, compared to standard systems* 

How do we know? Read the research.

* Results may vary. Variables affecting component life include, but are not limited to, material chemistry/fillers, flow rate, cycle rate, maintenance diligence, and system pressure.
