The GRACO 220157 is a medium volume surge tank 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 within GRACO equipment to dampen pressure fluctuations and ensure smooth operation in industrial applications.

Key Features:

• Surge Tank
• Medium Volume
• Stainless Steel
• 15 gpm (57 lpm) recommended maximum for peak performance
• Maximum gas charge pressure: 600 psi (42 bar, 4.2 MPa)
• Designed for integration with GRACO fluid delivery systems; compatible with 1 NPT(F) inlet and 1-1/4 NPT(F) outlet connections
• Reduces pulsation for consistent material delivery
• Electropolished stainless steel for durability and corrosion resistance
• Reliable performance in demanding industrial environments
• Ease of maintenance with available repair kits (e.g., diaphragm repair kit 220844)

Applications:
Used in industrial fluid delivery systems where consistent material flow and reduced pulsation are required, such as in lubrication, painting, and other process applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Use a minimum 25 mm (1 in.) diameter flexible hose between the pump and tank, and a hard or flexible pipe after the tank
• Install fluid shutoff and drain valves for safe operation
• Connect a bleed-type master air valve and ground wire as required for safety
• Follow all local and industry safety regulations during installation and maintenance
• Regularly inspect and maintain the surge tank and associated components
• Use only recommended repair kits and replacement parts
• Consult the equipment manual or a GRACO specialist for system design and troubleshooting
