Graco PR70 Benchtop Meter, Mix & Dispense System
Precision Two-Component Dispensing for Benchtop Applications
The Graco PR70 Benchtop Meter, Mix & Dispense System is designed for accurate dispensing of two-component materials ranging from low to high viscosity. It supports bonding, sealing, potting, gasketing, encapsulation, and syringe filling applications.
The PR70 Series provides precise mix ratio and shot repeatability, with fixed-ratio and variable-ratio configurations available. Depending on the model, material ratios range from 1:1 to 24:1 and shot sizes from approximately 2 to 70 cc.
The compact benchtop design supports operator-controlled use or integration with automated production equipment, providing a flexible solution for precise two-component material processing.
Features
- Precise Ratio & Shot Control: Positive displacement metering provides proven ratio accuracy up to ±1% and repeatable two-component dispensing.
- Flexible Ratio Configurations: Available in multiple configurations, including PR70 fixed-ratio, PR70v variable-ratio, and PR70e entry-level systems to support different production requirements.
- Durable Metering System: Proven metering components are designed for reliable two-component dispensing across a wide range of production applications.
- Flexible Control Options: Available with different control interfaces, including Local Control Module (LCM), Display Module (DM), and Advanced Display Module (ADM), depending on system configuration.
- Modular Material Feed Options: Optional tanks, agitation, heating, level sensing, and bulk-feed accessories are available to support different material characteristics and process requirements.
- Compact Benchtop Design: The compact benchtop system supports operator-controlled dispensing or integration with automated production equipment.
