Part 0551602 is a fluid section assembly that contains the primary pump components responsible for fluid transfer in sprayer systems. This assembly manages paint or coating flow, pressure generation, and material delivery through integrated valves and chambers.
A worn, damaged, or leaking fluid section assembly can lead to pressure loss, inconsistent spray patterns, or complete pump failure. Replacing the assembly restores proper fluid handling and reliable sprayer performance.
| Pressure generation | Creates and maintains spray pressure for material delivery |
|---|---|
| Fluid management | Controls paint or coating flow through pump components |
| Component housing | Contains valves, seals, and pressure chambers in one unit |
| External leaks | Visible fluid leakage from assembly housing or seams |
|---|---|
| Pressure loss | Inability to maintain consistent spray pressure |
| Internal wear | Excessive wear to multiple internal components |
| Casing damage | Cracks, fractures, or corrosion in assembly housing |
Part 0551602 is compatible with specific SprayTech sprayer models. Always confirm fitment using the correct parts diagram for your exact model and revision.
