Graco S25.13.0890.4 Shaft is a hardened, chrome-plated extended life component designed for reliable performance in demanding S25 pump applications.
The Graco S25.13.0890.4 Shaft is a precision-engineered internal component designed for demanding industrial environments. Manufactured from hardened tool steel and finished with a chrome-plated surface, this shaft delivers exceptional durability, corrosion resistance, and extended service life in high-cycle operations.
This extended life shaft plays a critical role in maintaining smooth pump operation by transferring motion between diaphragms in air-operated double diaphragm pumps. Its robust construction helps minimise wear, reduce maintenance frequency, and improve overall pump reliability.
| Material | Hardened tool steel for maximum strength and durability |
|---|---|
| Surface Finish | Chrome plated for corrosion resistance and reduced friction |
| Diameter | 25 mm precision-machined shaft |
| Length | Approximately 13.89 inches |
| Design | Extended life configuration for heavy-duty industrial use |
The shaft acts as the central drive component inside the pump, connecting diaphragms and enabling consistent fluid movement. Its hardened construction ensures resistance to mechanical stress, while the chrome-plated finish protects against chemical exposure and wear.
