Frequently Asked Questions

Common signs include loss of pressure, difficulty priming, material bypass into the wet cup, or pulsation at the gun. If packings/valves are worn, a pump rebuild typically restores performance.

The repair kit replaces core wear components (packings/valves/seals). A full pump assembly includes the complete displacement pump body and is used when internal surfaces or the rod/sleeve are damaged beyond service limits.

It fits the models listed above. Some series/region variants differ—always verify your pump model/series in your manual or by the machine ID plate before purchase.

Mostly standard hand tools plus pick tools for seals, thread sealant where specified, and a torque wrench. Keep the area clean to protect new packings. Follow the service manual procedures closely.

The pump is designed for typical architectural coatings (latex, acrylics, primers). Always check your material’s data sheet and ensure filters/tips are sized appropriately for viscosity and solids content.
