REF. 2
Titan 700-175 Potentiometer Cap
A replacement cap associated with the pressure-control potentiometer. Inspect it when the existing cap is missing, cracked or damaged.
700-175 replaces Titan 507748.
REF. 4
Titan 0508343 Fitting
A fluid-system fitting used at the designated main assembly connection. Check for damaged threads, leakage or physical damage before selecting a replacement.
REF. 6
Titan 0552155A Fluid Section Assembly
A genuine Titan pump lower assembly. Consider this listed assembly when the fluid section requires extensive repair. Compare the cost and suitability of a complete assembly against individual service parts.
REF. 7
Titan 0507798 Down Tube
The down tube provides a designated fluid-routing connection in the main assembly. Inspect for leakage, damage or restrictions when diagnosing fluid-delivery problems.
REF. 12
Titan 800-904 Bypass Tube
This bypass return component helps route fluid through the recirculation pathway. Inspect it for kinks, cracks, leakage or coating restrictions.
REF. 14
Titan 0507690 Bypass Valve Assembly
The bypass valve assembly controls a fluid-routing function used during priming and spraying. Inspect it when the sprayer has unwanted return flow or difficulty changing operating modes.
REF. 16
Titan 0507671 Fitting
A replacement fluid connection fitting. Match the exact part number rather than assuming that fittings with similar appearances have identical threads or dimensions.
FLUID CONNECTION
Titan 0507387 Fluid Hose
A fluid hose listed for the EPX2455 main assembly. Replace hoses showing abrasion, cuts, leakage, damaged fittings or other signs of deterioration.
System Operation
How EPX2455 Main Assembly Components Work Together
Pump Pressurization
The fluid section uses piston movement and valve action to draw in and pressurize coating material.
Fluid Connections
Fittings, tubes and hoses provide specified connections between fluid-system components.
Bypass Operation
The bypass valve and return pathway help direct material during priming and recirculation.
Pressure Adjustment
The pressure-control interface allows the operator to adjust the sprayer's operating pressure.
Troubleshooting
Common Titan EPX2455 Main Assembly Problems
| Symptom | Inspect | Recommended Check |
|---|---|---|
| Fluid leaks near a connection | 0508343, 0507671 fittings | Check threads, mating surfaces and the exact source of leakage. |
| Pump will not build pressure | 0552155A fluid section, 0507690 bypass valve | Check valve sealing, pump wear and unintended bypass flow. |
| Fluid returns during spray mode | 0507690 bypass valve | Check valve position and inspect the bypass mechanism for leakage. |
| Return line leaks | 800-904 bypass tube | Inspect the tube and connections for deterioration or damage. |
| Fluid hose is damaged | 0507387 fluid hose | Replace damaged hoses with the specified compatible part. |
| Pressure-control cap is missing | 700-175 potentiometer cap | Check the cap and underlying control for damage. |
| Poor material delivery | Down tube, fluid section, filters and suction system | Check restrictions, air entry, valve wear and filter condition. |
