What This Repair Kit Does

The displacement pump is responsible for drawing coating into the sprayer, pressurizing it, and delivering it to the spray gun.

Inside the pump are wear components that operate under extremely high fluid pressure. Normal operating hours, abrasive coatings, contamination, dried material, and lack of proper maintenance can eventually cause these components to wear.

A proper pump rebuild can restore pressure, prime performance, and fluid output without the expense of replacing the complete pump assembly.

Common Signs Your Pump May Need Rebuilding:

• Fluid leaking from the pump
• Sprayer will not maintain pressure
• Pump runs but produces little or no pressure
• Difficulty priming
• Pump cycles excessively while the gun is closed
• Uneven or inconsistent spray pressure
• Excessive packing leakage
• Loss of fluid output
• Worn or damaged internal pump components

Don't Overlook the Pump Hard Parts

When rebuilding an older airless pump, don't automatically assume that a repair kit will correct every problem.

Inspect the piston rod, cylinder, ball seats, balls, glands, and other hard parts for scoring, corrosion, or excessive wear. Installing new packings and seals against badly worn hard parts can result in a short-lived repair.

This is particularly important with older sprayers that may have already been rebuilt several times during their service life.

Keeping Older Graco Sprayers Working

Machines such as the Graco EM380, EM390, EM490, Ultra 400, Ultra 500, Nova and Super Nova have been around for many years, but plenty of them are still capable of doing productive work.

Older Graco equipment can sometimes be confusing because model names were changed, related machines were sold under different names, and some equipment was also marketed through Fuller O'Brien.

That's why we include the original Graco part number and compatible sprayer models whenever possible—making it easier to identify the correct repair parts before ordering.

Important:

This listing is for one aftermarket pump repair kit that replaces Graco Part #222587 / 222-587.

This is an aftermarket repair kit and is not manufactured by Graco.

Because these sprayers are older and may have been repaired or modified during their service life, verify the 222587 repair kit part number for the pump currently installed on your machine before ordering.
