Graco PR70™ Meter, Mix and Dispense Systems

The PR70 fixed ratio system accurately meters, mixes, and dispenses two-component medium to low-viscosity materials for potting, gasketing, sealing, encapsulation, and syringe filling. For variable ratio dispensing, the PR70 handles ratios from 1:1 to 24:1 and offers more control with an optional Advanced Display Module.

Other options include the PR70f for flow control and PR70 Servo for bead applications.

SYSTEM CONTROL OPTIONS

PR70 Dispense Systems (excluding PR70e) use intuitive user interfaces based on the Graco Control Architecture - a modular system of processing and control components. They provide similar interface functionality for systems using the same controller, simplifying training on operation. Maintenance and service also becomes easier because of the built-in troubleshooting and part replacement tools in the controller.
