Graco PR-X Meter Mix Dispense Systems
Description
The Graco PR-X is an advanced two-component (2K) metering, mixing, and dispensing system designed for precision applications in automated assembly. It utilizes high-accuracy linear drive technology to deliver consistent mix ratios and shot volumes, making it an ideal solution for bonding, sealing, and potting with epoxies, silicones, urethanes, and other 2K materials.
Available in both fixed and variable ratio configurations, the PR-X system features a compact, lightweight design that is perfect for robotic end-of-arm mounting. Its innovative “First-In-First-Out” (FIFO) fluid path minimizes material dwell time, ensuring optimal material freshness and reducing maintenance requirements.
Features
- Superior Ratio and Shot Accuracy : Advanced linear drive technology provides independent and precise control over each material component, maintaining a consistent ±1% ratio and shot repeatability for high-quality dispensing.
- Patented FIFO Fluid Path : The innovative “First-In-First-Out” (FIFO) design ensures that the material entering the meter first is also the first to be dispensed, preventing material stagnation and premature curing within the system.
- Lightweight for Robotic Integration : Engineered to be up to 40% lighter than comparable volumetric meters, the PR-X reduces the load on robotic arms, allowing for faster movement and the use of smaller, more cost-effective robots.
- Versatile Ratio Configurations : Available in both fixed ratio (PR-X) and variable ratio (PR-Xv) models to accommodate a wide range of chemical properties and evolving production requirements.
- Optimized Material Freshness : The compact fluid manifold and FIFO path minimize the amount of mixed material “resident” in the system, which is critical for handling fast-curing or high-viscosity 2K materials.
- Advanced Control and Communication : Seamlessly integrates with factory automation systems via industry-standard protocols such as EtherNet/IP, PROFINET, or DeviceNet, enabling real-time process monitoring and data collection.
- Rugged and Durable Design : Constructed with high-wear resistant materials to handle abrasive fillers and high-pressure applications (up to 3,000 psi), ensuring a long service life and reduced maintenance.
