Surge Suppressors
Surge suppressors (also known as surge tanks or pulsation dampeners) reduce unwanted pulsation in paint circulation system lines. During pump changeovers, fluid pressure between pumps and applicators briefly drops. Surge suppressors make the pressure consistent, keeping fluid flow smooth.
Minimize Pulsation with Minimal Effort
Manufacturers concerned about pulsation on their paint lines can set and forget Graco’s active surge suppressor. It automatically adjusts itself for peak performance in changing conditions. Once you set it up, you can forget about manual adjustments.
