The Graco 25U536 Kit, Conversion, Grease Cup, 140 is an OEM upgrade kit designed to convert compatible Graco Z-Pump systems into a sealed grease cup lubrication configuration, enhancing sealing performance and reducing internal wear.
Built for heavy-duty industrial pumping applications, it replaces outdated lubrication designs with a controlled grease-fed sealing system for improved reliability and extended service life.
The 25U536 is a factory-engineered conversion kit used to upgrade Graco Z-Pump Size 140 systems to a modern grease cup lubrication setup. It eliminates older wet cup components and replaces them with precision sealing elements designed for consistent lubrication control.
This conversion improves pump efficiency by maintaining proper grease distribution across critical sealing surfaces, reducing friction and preventing premature wear in continuous-use environments.
Designed to modernize lubrication systems, the kit ensures stable grease delivery to sealing components, improving performance stability in high-pressure industrial applications.
