Upgrades Graco Z-Pump Size 160 systems to a sealed grease cup lubrication setup, improving sealing control and reducing wear in high-capacity industrial pumping applications.
| Equipment Type | Compatibility Details |
|---|---|
| Z-Pump Size 160 Systems | Direct OEM conversion for Graco Z-Pump 160 assemblies requiring grease cup upgrade or replacement. |
| Legacy Graco Pump Units | Supports older wet cup lubrication configurations transitioning to sealed grease cup systems. |
| Industrial High-Pressure Pumps | Compatible with select Graco industrial pumping systems using size 160 throat assemblies. |
The Graco 25U538 Kit, Conversion, Grease Cup, 160 is an OEM-grade conversion kit designed to upgrade compatible Graco Z-Pump systems into a sealed grease cup lubrication configuration for improved sealing control and reduced wear.
Engineered for heavy-duty industrial applications, it replaces outdated wet cup designs with a controlled grease-fed sealing system that enhances reliability and extends equipment service life.
The 25U538 is a factory-engineered conversion kit used to modernize Graco Z-Pump Size 160 systems by replacing legacy lubrication assemblies with a sealed grease cup system. It ensures proper grease distribution across sealing components for consistent performance.
This upgrade reduces internal friction, minimizes maintenance intervals, and extends the lifespan of pump components operating in continuous-duty environments.
Designed to stabilize lubrication performance in high-capacity pumping systems, the kit ensures controlled grease delivery to critical sealing points, improving operational reliability and reducing wear.
