The GRACO 238986 is a high volume surge tank constructed from stainless steel with PTFE components, designed to reduce pulsation and ensure consistent material delivery in high flow rate systems. It is intended for use within GRACO equipment to dampen pressure fluctuations and maintain uniform spray patterns.

Key Features:

• Surge Tank
• High Volume, Inlet/Outlet: 2 NPT(F)
• Stainless Steel, PTFE
• 20 GPM (76 L/min)
• 300 psi (2.1 MPa, 21 bar)
• Compatible with GRACO high flow rate systems; 2 NPT(F) inlet/outlet
• Reduces pulsation for consistent material delivery and uniform spray pattern
• Ideal for large, high flow rate systems
• Electropolished stainless steel for durability and corrosion resistance
• PTFE components for chemical compatibility
• Reliable performance in demanding industrial environments

Applications:
Used in industrial applications requiring consistent material delivery and pulsation reduction, such as large-scale painting, lubrication, and fluid transfer systems. Suitable for mining, agriculture, and manufacturing environments.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Ensure proper alignment and secure connection of 2 NPT(F) inlet/outlet
• Follow manufacturer’s recommended torque specifications for fittings
• Check for leaks after installation
• Regularly inspect for wear and replace diaphragm or seals as needed
• Do not exceed maximum working pressure of 300 psi (2.1 MPa, 21 bar)
• Periodically check gas charge pressure and adjust if necessary
• Inspect for signs of corrosion or damage
• Replace diaphragm repair kit (if applicable) as per maintenance schedule
• Relieve gas pressure before performing maintenance
