Conversion kit that upgrades compatible GRACO Z-Series pump assemblies to a grease cup lubrication system, improving seal lubrication and reducing wear in Size 70 configurations.
| Pump Size / Model Series | Compatibility Details |
|---|---|
| GRACO Z-Pump Size 70 | Direct replacement conversion kit for upgrading older Z-Pumps to grease cup configuration. |
| Z-Series Chemical Pumps (Legacy Models) | Compatible with older units requiring retrofit from obsolete wet cup / seal designs. |
| Industrial Fluid Handling Pumps | Used in seal lubrication upgrade applications for select GRACO industrial pump assemblies. |
The Graco 25U528 Kit, Conversion, Grease Cup, 070 is engineered specifically for GRACO Z-Series pump systems where a grease cup lubrication upgrade is required. It is part of a structured conversion range designed to modernize older pump sealing assemblies and improve lubrication efficiency in high-pressure industrial applications.
The Graco 25U528 Kit, Conversion, Grease Cup, 070 is an OEM-grade maintenance and upgrade kit used to convert compatible GRACO pump assemblies from older sealing or wet-cup configurations into a modern grease cup lubrication system.
This conversion kit is designed to maintain optimal lubrication of the pump throat seals by introducing a controlled grease reservoir. This reduces wear, prevents premature seal failure, and ensures smoother piston operation under continuous-duty industrial conditions.
In GRACO’s Z-Pump system architecture, each kit number corresponds to a specific pump size range, and 25U528 is matched to pump size 70, ensuring precise fitment and OEM-level performance restoration.
By replacing outdated throat seal assemblies, the kit improves reliability, reduces downtime, and supports long-term operational stability in demanding fluid handling environments.
