Installation & Maintenance Tips

Use pump armor or equivalent storage fluid when idle to protect check valves and packings.
After install, prime thoroughly and check for leaks/seal integrity before loading coating.
Track hours and repack proactively—MaxLife extends life, but packings are wear items.
Keep the manifold filter and gun filter matched to your tip size to reduce pulsation and wear.

Frequently Asked Questions

It’s a complete displacement lower (piston pump assembly) designed to swap in via ProConnect. Packing and valve components are included as part of the assembled lower.

GH 230 ProContractor Series
GH 300 ProContractor Series

MaxLife components use hardened wear surfaces that typically last longer between repacks, especially in high-duty cycles and abrasive materials.

No special tools are required beyond standard hand tools. Follow safety procedures, relieve pressure, and use the ProConnect process to remove the old lower and install the new one.

Keep a 287813 Packing Kit for scheduled repacks and the 249177 Piston Valve & 240918 Foot Valve kits for check-valve refreshes. For heavy use, stocking the 287817 Sleeve and 288470 Rod is recommended.
