Graco Electric fixed ratio (EFR) metering system

The Graco EFR (Electric Fixed Ratio) Metering System is a high-precision solution for metering, mixing, and dispensing two-component sealants and adhesives. It is designed to deliver accurate and repeatable material application for processes such as gasketing, bonding, sealing, potting, and shot dispensing. The EFR integrates mechanically linked Z-pumps, advanced control architecture, and a powerful drive system to ensure on-ratio performance and consistent flow—even during pump changeovers. Ideal for manual or robotic applications, the EFR adapts to a wide range of materials and is easy to operate, configure, and maintain.

Choose the Graco EFR Metering System for unmatched precision, versatility, and ease of use. Whether you need to dispense micro-shots or high-volume flow, the EFR adapts to your production needs. Contact us today for more details!
