The Graco 25U533 Kit, Conversion, Grease Cup, 100 is a genuine OEM conversion kit engineered to upgrade older Graco Z-Series chemical pumps that were originally manufactured without a grease cup or equipped with an obsolete wet cup assembly. This conversion package replaces the complete throat seal and cup assembly, helping maintain proper lubrication around the displacement rod while extending seal life and reducing maintenance requirements.
Designed for Pump Size 100 configurations, this kit provides an efficient solution when original throat seal components become worn, damaged, or no longer available. Rather than replacing individual obsolete parts, the conversion kit updates the pump to the newer grease cup design used in current service configurations.
During operation, the grease cup helps maintain lubrication around critical sealing surfaces within the pump throat area. By converting older pump designs to the updated grease cup configuration, the 25U533 kit assists in protecting internal components from contamination, minimizing seal wear, and supporting consistent pump performance in demanding sealant and adhesive processing applications.
