Titan 315-932 Displacement Rod
Titan part 315-932 is a displacement rod used in the fluid pump section of compatible Hydra airless sprayers. It connects the piston to the drive train, converting rotary motion into reciprocating movement to pump paint. A worn or bent rod can cause loss of pressure, erratic operation, or pump failure. Replacing the displacement rod restores proper pump performance and consistent spray output.

Displacement Rod for Hydra M 2000, M 4000, and Hydra Pro Super Airless Sprayers
The Titan 315-932 Displacement Rod is a precision‑machined component that forms the core of the fluid pump assembly. It transmits reciprocating motion from the drive system to the piston, drawing paint into the cylinder and then forcing it out under high pressure. On Hydra M‑series and Hydra Pro Super sprayers, this rod is essential for maintaining consistent pressure and reliable operation.
Over time, the displacement rod can become scored, bent, or worn, leading to pump inefficiency, pressure loss, or complete pump failure. Replacing a damaged rod with this genuine Titan part restores proper stroke length, seal alignment, and overall pump performance.
What it does and when to replace it
| Power transmission | Converts drive rotation into linear reciprocating motion for the pump |
|---|---|
| Pressure generation | Drives the piston to create high‑pressure fluid output |
| Seal interface | Works with packings to prevent fluid bypass and maintain efficiency |
| Pressure loss | Sprayer cannot maintain pressure or struggles to build pressure |
|---|---|
| Erratic output | Intermittent or pulsing spray despite proper inlet/outlet valves |
| Visible damage | Scoring, nicks, bending, or excessive wear on the rod surface |
| Leakage | Fluid leaking from the pump packing area due to worn rod surface |

Related parts commonly serviced together
When replacing the displacement rod, it's often advisable to renew the sealing components to ensure a complete repair.
Includes seals, o‑rings, and packing that ride on the rod; should be replaced to prevent leaks.
Inspect the cylinder for scoring or wear; replace if damaged to restore pump efficiency.
Worn valves can mimic rod failure; check and replace if necessary for full system performance.
