The Impact 805-246A fluid section assembly is the primary pumping component used to move coating material from the supply into the spray hose under high pressure. It houses wear components such as packings, pistons, and valves that work together to maintain consistent output during spraying.
Over time, normal wear or material contamination can reduce pumping efficiency, cause pressure fluctuations, or lead to leaks. Replacing the fluid section assembly restores proper material delivery and dependable sprayer performance.
