About the Graco 189317 Displacement Rod
The Graco 189317 Displacement Rod (also called a pump piston rod / Q-rod) is a critical drive component that links the pump’s drive mechanism to the fluid piston. On the up-stroke it draws coating into the chamber; on the down-stroke it forces material into the hose for consistent, high-pressure delivery.
- Genuine Graco OEM component engineered for durability and fit.
- Designed for high-ratio, heavy-duty industrial pumps (DF1100 family).
- Precision finish to help maintain packings and extend pump life.
- Ideal when experiencing scoring, excessive play, or inconsistent pressure due to rod wear.
