Pro Tips for Long-Term Equipment Reliability

Taking care of your Graco 455 ST Pro Hi-Boy pump isn’t just about reactive repairs—it’s about proactive maintenance. Here’s how to keep your sprayer performing like new:

1. Maintain a Maintenance Schedule

Document usage intervals and adhere to a strict maintenance calendar. Replace packings, o-rings, and filters regularly to avoid downstream failures.

2. Lubricate Regularly

Each time you install a new seal kit, add Graco-approved lubricant. It reduces wear and extends the lifespan of internal components.

3. Keep a Spare On Hand

Nothing kills momentum like a blown hose or clogged tip. Stock a Graco sprayer accessories kit or a secondary Graco 455 pump assembly to minimize lost time during big jobs.

4. Organize With Color-Coding

Use color-coded bins to categorize similar parts like graco spray tips, pump filters, and gun seals. This makes it easier for crews to find what they need—fast.
