Enclosed wet cup kit for Graco L100CM

The enclosed wet cup kit 255696 is a maintenance component for Graco high-pressure pumping and spraying equipment. It functions by housing a lubricating or protective fluid around the piston rod, creating a barrier that keeps the rod and seals clean and lubricated. This design minimizes evaporation and prevents contaminants from reaching critical internal surfaces during the pumping of materials.

This kit is compatible with Graco L100CM and L100CS models. These air-operated pumps are utilized in industrial applications for coatings, sealants, adhesives, and lubricants. The kit includes the cup housing and the necessary seals to maintain the integrity of the pump assembly.

In high-pressure pump systems, a wet cup assembly is used to prevent the premature wear of the piston rod and seal packings. By maintaining a constant layer of fluid around the rod, the system reduces friction and prevents abrasive materials from entering the seal area, which helps maintain consistent pump pressure and prevents fluid leakage.
