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. Its modular design provides the freedom and flexibility to configure the components for specific application requirements. The HFR provides an advanced system that is reliable, yet affordable.

Accurate, On- ratio Dispense

With accuracy and repeatability, the Graco HFR lets you hit a specific ratio and volume – 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 a constant pressure or 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. Learn more about the HFR Metering System.
