The GRACO HFRSA8 is a hydraulic fixed ratio meter, mix, and dispense system designed for high-volume, accurate dispensing of two-component materials such as silicones. It is constructed with robust materials including zinc-plated carbon steel, PTFE, nylon, polyurethane, UHMW, polyethylene, fluoroelastomer, acetal, leather, aluminum, tungsten carbide, nickel- and zinc-plated carbon steel, stainless steel, and chrome plating. It is intended for use in industrial applications requiring precise mixing and dispensing of adhesives, sealants, or silicones.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the system.
• Ensure proper electrical supply: 400V/3 phase, 50/60 Hz, 360–440V
• Check fluid inlet and outlet connections for compatibility (e.g., 3/4" NPT(f) inlet, 1/2" NPT(f) outlet)
• Verify air inlet requirements: 1/4" NPS, 40–100 psi
• Follow manufacturer’s guidelines for fluid pressure and temperature limits
• Regularly inspect and maintain wetted parts for wear and contamination
• Use only recommended fluids and materials
• Perform routine maintenance as per manual
• Monitor system for leaks and abnormal noise
• Keep documentation and service records updated
