Titan 704-180 Pump Block
OEM Titan Pump Component
Titan 704-180 Pump Block is a genuine OEM fluid housing (also referenced as a pump manifold) for the Titan 340 and 440i sprayers. It provides the central structure for the piston, packings, valves, and filter, maintaining pressure and fluid flow.
Compatibility
Replace if the housing is cracked, the cylinder bore is deeply scored, or threads for valve retainers or mounting bolts are stripped. Always install new packings and seals during reassembly.

Titan 704-180 Pump Block for 440i & 340 Service
Titan 704-180 is a genuine OEM pump block (also referenced as a pump manifold) for the Titan 440i and 340 Airless Sprayers. It forms the central fluid housing that contains the piston bore, packings, inlet and outlet valves, and internal filter, providing the structural integrity and fluid passages required for high-pressure paint delivery.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine OEM pump block/fluid housing for the Titan 440i and 340. Described by specialist parts retailers as a "Pump Manifold" that houses the internal manifold filter and serves as a connection point for fluid sections. The Titan 340/440i manuals describe the pump block as housing the piston, packings, and valves, secured by two mounting screws. |
| Function | Provides the precision cylinder bore for piston movement, houses upper and lower packings, mounts the inlet and outlet valves, contains the pump filter, and provides fluid passages for paint flow under high pressure. Attaches to the pump housing via two mounting screws. |
| Compatible Titan Machines | Titan 440i (primary fit, confirmed in manual and catalog); Titan 340 International Model. Always confirm fitment using your exact model's parts diagram and serial number. |
| OEM Part Number | 704-180 Pump Block / Pump Manifold. |
| Replacement Indicators | Cracked housing causing external leak; deeply scored or worn cylinder bore preventing proper sealing; stripped threads for valve retainers or mounting bolts; corrosion or pitting from water or abrasive materials. |
| Related Parts Commonly Serviced Together | Piston / rod assembly (inspect for wear or scoring); packing set (always install new packings when rebuilding); inlet and outlet valve kits (replace to avoid rework); pump filter (inspect and replace if clogged). |
| Common Problems Solved | Restores proper piston alignment, valve seating, and hydraulic integrity. Eliminates pressure loss, fluid bypass, external leaks, and complete pump failure caused by a compromised housing. |
| Why Genuine OEM | Precision-machined bore and thread specifications ensure proper fit and sealing. A damaged or low-quality block can cause repeat seal failures, pressure loss, and further component damage. |
Service guidance: Before replacing the pump block, relieve system pressure and disconnect power. Inspect for visible cracks, scoring inside the bore, or damaged threads. The pump block is secured by two mounting screws accessed with a 3/8" hex wrench. During reassembly, ensure the transducer is properly aligned with the hole in the pump block to avoid o-ring damage. Always install new packings and seals when reinstalling valves and piston. Torque fasteners to manufacturer specifications.
