Find Titan EPX2155 Piston Pump Replacement Parts
The piston pump is a central part of the Titan EPX2155 fluid-delivery system. Its internal components work together to draw coating material from the supply, move it through the pump and deliver pressurized fluid toward the downstream spray system.
Worn packings, damaged sealing components, contaminated valve areas or wear within the pump can contribute to difficult priming, reduced output, pressure loss, fluid leakage or inconsistent material delivery. Correct diagnosis and accurate parts identification help avoid unnecessary replacement of unrelated components.
How to Find the Correct EPX2155 Piston Pump Part

Verify that the sprayer being serviced is the Titan EPX2155 and identify the applicable machine configuration.
Open the Pump Diagram
Use the applicable EPX2155 piston pump exploded illustration to locate the internal or external pump component requiring service.
Match the Callout
Match the numbered diagram callout to the corresponding part description and replacement part number in the parts list.
Verify Part & Quantity
Confirm the exact replacement part number, description and required quantity before ordering.
How the EPX2155 Piston Pump Moves Coating Material
During operation, the pump's reciprocating components create the fluid movement needed to draw material into the pump and move it toward the pressurized outlet. Packings and sealing components help control fluid around the moving pump parts, while inlet and outlet valve components control the direction of material flow.
Piston Components
The piston and related moving components create the reciprocating pumping action required to move coating material through the pump.
Packings & Seals
Pump packings and applicable seals help control fluid around moving components and maintain the conditions needed for effective pumping.
Inlet Valve Components
The applicable inlet valve components support one-way material flow into the pump during the pumping cycle.
Outlet Valve Components
Outlet-side valve components help direct pumped coating material toward the pressurized fluid path of the sprayer.
EPX2155 Piston Pump Components to Inspect
Inspect diagram-listed piston components for wear, scoring, coating buildup or physical damage that can affect pumping performance.
Worn pump packings can contribute to leakage, pressure loss and reduced pumping efficiency.
Inspect applicable inlet valve components for contamination, wear or damage when the pump has difficulty drawing coating material.
Check outlet-side valve components when the pump cannot maintain normal fluid delivery or pressure.
Inspect applicable seals and O-rings for cuts, flattening, deterioration or damage that may allow fluid leakage.
Verify diagram-listed fittings, retainers and related pump hardware for damage, looseness, contamination or missing components.
Diagnose EPX2155 Piston Pump Problems
Priming, pressure and fluid-delivery problems can originate in several areas of an airless sprayer. Inspect the material supply and suction path before disassembling the piston pump, then evaluate the pump and downstream fluid system as needed.
1. Check Material Supply
Confirm adequate coating material and verify that the suction path is not restricted or drawing unwanted air.
2. Inspect Inlet Components
Check the applicable inlet valve components for contamination, wear or conditions that prevent proper material intake.
3. Inspect Packings & Piston
Look for leakage and signs of packing or piston wear that can reduce pump efficiency or pressure performance.
4. Check Outlet & Fluid Path
Inspect outlet-side pump components and downstream fluid-system parts when material intake is normal but pressure or output remains poor.
Common Titan EPX2155 Piston Pump Problems
These symptoms can help narrow the inspection area, but they do not automatically confirm a failed pump component. Diagnose the surrounding fluid system before ordering replacement parts.
| Symptom | What to Inspect | Repair Direction |
|---|---|---|
| Pump Will Not Prime | Material supply, suction path and applicable inlet valve components. | Eliminate suction restrictions or air leaks, then inspect inlet-side pump components. |
| Reduced Pump Output | Packings, piston components, inlet and outlet valve areas. | Inspect for wear, contamination or internal leakage before selecting replacement parts. |
| Cannot Maintain Pressure | Pump valves, packings, piston components and downstream fluid system. | Determine whether pressure loss is internal to the pump or elsewhere in the fluid path. |
| Fluid Leakage at Pump | Packings, seals, O-rings, fittings and mating surfaces. | Relieve pressure, identify the exact leak source and replace the verified worn or damaged components. |
| Inconsistent Material Delivery | Material supply, suction path, pump valves, packings and downstream fluid path. | Diagnose the complete fluid path before determining which pump component requires service. |
