• Fixed Ratio Proportioning Pump
• President Hydra-Cat, Three Displacement Pumps, 2:1 Mix Ratio
• Stainless steel, carbon steel, chrome plating, tungsten carbide, Teflon®
• Maximum fluid inlet pressure: 750 psi (5.1 MPa, 51 bar); Maximum output pressure: 20.4 MPa (204 bar)
• Designed for use with two-component materials in industrial proportioning systems
• Accurate proportioning of two-component materials
• Air-powered operation
• Durable construction for long service life
• Reliable performance in demanding environments
• Ease of maintenance due to robust design

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 GRACO’s 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
