Other Graco pump units with exposed piston or rod linkages

Product Description

The Graco 15B589 Pump Rod Cover is an OEM protective sleeve or guard that fits over the pump rod in compatible Graco systems. Its primary function is to shield the rod linkage from dust, debris, moisture, and chemical exposure, while also helping contain lubricant or material spray in high‑cycle operations.

By providing a barrier around the rod, it reduces wear on the rod surface, helps maintain cleaner operation, extends service intervals, and supports the long‑term reliability of the pump assembly. Constructed from sturdy molded material sized to fit precisely, the 15B589 takes the place of worn or missing covers that can compromise system performance.

Why It Matters

In industrial sprayer or pump systems, exposed rods or linkages are vulnerable to abrasion, chemical attack, and ingress of foreign material which can lead to premature wear or failure. The 15B589 cover acts as a simple but effective line of defense — maintaining your pump’s operational integrity, reducing maintenance frequency, and preserving performance.

Installation & Maintenance Guidance

Inspect the existing rod cover during routine maintenance — if it’s cracked, missing or degraded, replace with the 15B589.
Ensure the cover is properly seated around the rod and secured per the equipment’s assembly drawings.
Clean any residual materials, dust or chemical deposits before installing the new cover to avoid trapping contaminants.
After installation, verify the rod moves freely within the cover and the cover remains in place during pump cycles.

Frequently Asked Questions

It serves as a protective sleeve over the pump rod and associated linkages, guarding against contamination, wear, and corrosion in heavy‑duty spray or pump systems.

Replace it if you observe cracks, material degradation, missing sections, or if contaminants are visible around the rod — any of which indicate the cover no longer shields properly.

While a generic cover might fit, using the genuine 15B589 ensures exact dimensional fit, correct material spec, and alignment with the manufacturer’s intended protection — thereby preserving optimal performance and warranty integrity.
