Installation & Usage Tips
- Always depressurize and flush the system before installation or maintenance.
- Use proper alignment jigs or guides to ensure repeatable insertion depth for consistent seal compression and avoid side-loading the shaft.
- Inspect or replace associated packings and seals when installing the shaft to maintain leak-free operation.
- For applications involving particulate or abrasive materials, add a fine (e.g. 5-micron) upstream filter to reduce wear and extend component life.
- Use appropriate lubrication compatible with your fluid system to minimize friction and prolong seal and shaft interface life.
Frequently Asked Questions
The 162632 ShaftPlunger acts as the primary reciprocating shaft in piston-driven pump modules. It transfers motion to the piston/packing assembly, ensuring consistent fluid displacement and reliable high-pressure pump operation. Its hardened, precision-ground design minimizes wear and maintains alignment under heavy duty cycles.
This part is listed as compatible with Graco HDInLine and TSL series pump modules. Always verify your pump module’s part diagram or serial number to confirm compatibility before ordering. :contentReference[oaicite:3]{index=3}
As a guideline, inspect the shaft, packing, and seal interfaces every ~1,000 operating hours. Also ensure regular maintenance of upstream filtration and lubrication to prolong service life and prevent premature wear.
