Applications:
Industrial mixing and dispensing of two-component materials such as resins and hardeners, suitable for applications in manufacturing, construction, and maintenance where precise material ratios are critical.
Installation Notes:
- Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the proportioning system.
- Label all pumps, hoses, and regulators to indicate resin or hardener side for correct installation and operation
- Mount fluid pressure gauges at pump inlets to monitor feed pressures
- Never exceed 25% of the Hydra-Cat pump outbound fluid pressure on the feed supply
- Follow GRACOs recommended installation guidelines for safety and efficiency
- Regularly inspect and maintain wetted parts for longevity
- Regularly check and replace wetted parts as needed
- Monitor air consumption and fluid pressures during operation
- Ensure proper lubrication and filtration of air supply
- Consult GRACO documentation for specific maintenance intervals and procedures
