The GRACO 238988 is a high volume surge tank constructed from stainless steel, designed to reduce pulsation and ensure consistent material delivery in high flow rate systems. It features 1.5 in (38.1 mm) sanitary tri-clamp inlet/outlet connections and is intended for use in industrial finishing and fluid handling applications.

Key Features:

• Surge Tank
• High Volume, 1.5 in (38.1 mm) sanitary tri-clamp inlet/outlet
• Stainless steel
• 20 gpm (75.7 lpm)
• 300 psi (20.7 bar)
• Compatible with a variety of finishing materials; suitable for in-line flow configuration
• Reduces pulsation for consistent material delivery and uniform spray pattern
• Electropolished stainless steel for enhanced corrosion resistance and cleanability
• Sanitary tri-clamp connections for easy installation and maintenance
• In-line flow configuration for quick flushing and color changes
• Ideal for large, high flow rate systems

Applications:
Used in industrial finishing, paint, and fluid handling systems where consistent material delivery and reduced pulsation are required. Suitable for large-scale operations such as manufacturing, mining, and agriculture.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing systems.
• Ensure all connections are secure and leak-free before operation
• Follow manufacturer guidelines for maximum flow and pressure ratings
• Regularly inspect for wear and maintain cleanliness to prevent contamination
• Use compatible fluids and materials as specified by GRACO
• Flush the surge tank regularly to prevent buildup and ensure smooth operation
• Inspect diaphragms and seals for wear and replace as needed
• Keep records of maintenance and part replacements for traceability
