Precision Electronic shot and bead dispensing technology for two component materials

The Graco Electric Fixed Ratio (EFR) meter, mix and dispense system for two component sealant and adhesive delivery is ideal for applications requiring precision dispense, The EFR provides superior control over material dispense rates for critical bead, encapsulation, mold filling, and lamination applications. Feel comfortable choosing a unit that is easy to configure and very easy to maintain. The EFR offers a wide range of ratio choices and can be connected to multiple material systems. ​​​

The electric motor directly controls the movement in the pumps so that the requested flow rate is achieved directly from the start. With the additional automatic calibration cycle, snake heads at the start and end are eliminated.
​The EFR gives you the versatility to choose the material and flow rates you need no matter your project requirements. While the motor is powerful enough to give you a high output up to 3.2L per minute, the precise encoder helps you control the flow to reach very low flows or small shots consistently.
