The GRACO 238987 is a high volume surge tank (pulsation dampener) constructed from stainless steel, designed to reduce pulsation in fluid delivery systems for consistent material flow and uniform spray patterns. It is intended for use in large, high flow rate systems within GRACO equipment, particularly in paint circulation and finishing applications.

Key Features:

• Surge Suppressor (Pulsation Dampener)
• High Volume, 2 in (50.8 mm) sanitary tri-clamp inlet/outlet
• Stainless steel (electropolished), PTFE compatible materials
• 20 GPM (75.7 LPM)
• 300 PSI (20.7 Bar)
• Compatible with a variety of finishing materials; multiple fluid connection options for global system requirements
• Reduces pulsation for consistent material delivery and uniform spray pattern
• In-line flow configuration for easy flushing and quick color changes
• Easy to maintain and reliable for high-duty cycle applications
• Sanitary tri-clamp connections for hygienic and secure fittings

Applications:
Ideal for large, high flow rate paint circulation and finishing systems where consistent pressure and flow are required. Commonly used in industrial manufacturing, automotive, and finishing applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure all connections are secure and properly tightened before pressurizing the system
• Follow manufacturer guidelines for gas charge pressure and maximum working pressure
• Regularly inspect for leaks and wear, and replace diaphragm or seals as needed
• Use appropriate tools and safety equipment during installation and maintenance
