Hydraulic Fixed Ratio Metering System

The Graco HFR metering system is a meter, mix and dispense system that accurately meters, mixes and dispenses multiple sealant and adhesive materials – from elastomers to epoxies. Its modular design, provides the freedom and flexibility to configure the components that are essential for specific application requirements. Along with Graco technologies and precision dispensing capabilities, the HFR provides a system that is advanced and reliable, yet affordable. Learn more about the HFR Metering System.

Accurate, On-ratio Dispense

With its accuracy and repeatability, the Graco HFR lets you hit a specific ratio and volume – the first time, and every time. Static, dynamic, or impingement mixing options along with positive displacement pump technology will improve throughput while reducing scrap and rework. The system is capable of producing either a constant pressure material output or a constant flow rate material output. Closed-loop technology provides pressure and flow control for a smooth dispense while long-lasting wear parts mean lower cost of ownership.
