Main Assembly Overview
Buy Genuine Titan EPX2355 Piston Pump Main Assembly Parts
The Titan EPX2355 Main Assembly brings together components used in the sprayer's material intake and return-fluid system. The suction assembly and siphon tube provide a path for coating material to enter the pump, while the return tube supports the flow path used during applicable priming and pressure-relief operations.
Maintaining these components helps support consistent material supply and proper fluid routing. Cracked tubing, damaged connections, clogged intake passages or missing components can interfere with priming and sprayer operation. A careful inspection can help determine whether an individual part needs replacement.
AllTitanParts currently lists three genuine Titan OEM parts in this category. Each has its own factory diagram reference and part number, allowing you to identify a targeted replacement without assuming that the entire sprayer or pump requires replacement.
