The GRACO 218509 is a high volume surge tank designed to reduce fluid surging and pulsation in high- or medium-volume, low-pressure fluid systems. Constructed primarily from carbon steel, it is intended for use within GRACO equipment to ensure consistent material delivery and uniform spray patterns in demanding industrial applications.

Key Features:

• Surge Tank
• 218509
• Carbon Steel, Electroless Nickel-Plated Steel, UHMW Polyethylene, Fluoroelastomer, PTFE
• 20 gpm (75.7 lpm)
• 300 psi (20.7 bar) standard; up to 600 psi (42 bar) for certain configurations
• Designed for use with GRACO high- and medium-volume fluid systems; compatible with 2 NPT(f) inlet/outlet connections
• Reduces pulsation for consistent material delivery and uniform spray pattern
• Robust construction for reliability in demanding environments
• Ease of maintenance with accessible components
• Suitable for large, high flow rate systems

Applications:
Ideal for large-scale industrial applications requiring consistent fluid delivery, such as mining, agriculture, and manufacturing. Used to dampen pulsation and ensure smooth operation of high-volume fluid systems.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, compatibility, and safety within GRACO equipment.
• Ensure all connections are secure and leak-free before operation
• Follow GRACO’s recommended installation procedures for surge tanks
• Regularly inspect and maintain the surge tank to prevent buildup and ensure longevity
• Use only compatible fittings and accessories as specified by GRACO
