Graco Electric fixed ratio (EFR) metering system

The Graco Electric Fixed Ratio (EFR) Metering System is an electrically driven proportioner for two-component sealants and adhesives, designed for applications that require consistent shots and beads.

The system supports accurate, repeatable dispense with a consistent ratio and can be used for continuous flow applications. Its electric motor directly controls pump movement, helping achieve precise material control across low-flow, small-shot and higher-flow production requirements.

EFR is suitable for a wide range of materials, from thin and unfilled products to viscous and abrasive materials. The system is easy to configure, operate and maintain, and can be integrated into manual or robotic dispensing applications.
