Graco Hydraulic Fixed Ratio (HFR) System
Description
The Graco HFR Hydraulic Fixed Ratio System is a modular metering, mixing, and dispensing platform designed for high-precision two-component (2K) applications. By utilizing hydraulic drive technology, the system provides constant pressure and flow rates, making it an ideal solution for structural bonding, potting, and joint filling in demanding manufacturing environments.
Its flexible design allows for a wide range of pump sizes and configurations to meet specific material requirements. The system’s advanced control technology ensures that chemical ratios remain consistent from the start of the shot to the end, reducing material waste and ensuring high-quality output.
Features
- High-Precision Hydraulic Drive : The system utilizes a powerful hydraulic drive to provide constant pressure and flow rates, ensuring consistent material delivery even with high-viscosity fluids.
- Accurate Fixed Ratio Metering : Engineered with positive displacement technology, the HFR maintains a strict mix ratio accuracy of ±1%, ensuring that two-component materials cure correctly and perform as intended.
- Modular and Configurable Platform : The modular design allows for a wide selection of pump sizes and configurations, making it easy to tailor the system to specific flow rates, ratios, and material chemistries.
- Advanced Process Monitoring (ACM) : Equipped with the Advanced Control Module (ACM), the system tracks real-time dispensing data and alerts operators to any pressure or ratio deviations, ensuring high process reliability.
- Reduced Material Waste : The precise “start-to-stop” ratio control minimizes the amount of off-ratio material produced during each shot, significantly reducing scrap and cleaning costs.
- Durable and Low Maintenance : Features robust horizontal pumps and high-quality seals designed for long-life performance in demanding industrial environments, with easy-to-access components for rapid servicing.
- Versatile Material Compatibility : Capable of handling a broad spectrum of 2K materials, including epoxies, silicones, urethanes, and polysulfides, as well as abrasive fillers.
- Seamless Automation Integration : Supports industry-standard communication protocols (such as EtherNet/IP or PROFINET) for easy integration into robotic cells and automated assembly lines.
