The suction set forms the material-intake path between the coating supply and the sprayer's piston pump. During priming and normal operation, the pump must be able to draw material through this intake path without excessive restriction or unwanted air entering the system.
A damaged suction component, restricted strainer, loose connection or compromised intake seal can contribute to difficult priming, intermittent material flow, pressure fluctuation or reduced pump output. Inspect the complete suction path before assuming that a priming problem requires internal piston-pump repair.
How to Find the Correct EPX2155 Suction Set Part
Confirm EPX2155
Verify the sprayer model and confirm that the applicable suction set is identified as P/N 0551104.
Open the Suction Diagram
Use the applicable EPX2155 Suction Set Assembly exploded illustration to locate the intake component requiring service.
Match the Callout
Match the numbered diagram callout to its corresponding 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 Suction Set Supplies the Piston Pump
The suction set allows coating material to travel from the supply container to the pump inlet. Reliable intake depends on an unrestricted material path, secure connections and serviceable sealing components. Problems anywhere along this path can interfere with priming and normal pump performance.
Suction Components
The intake components provide the path used to draw coating material from the supply container toward the piston pump.
Strainer Components
An applicable inlet strainer helps reduce the entry of larger debris into the material-intake path and pump.
Seals & Connections
Serviceable intake connections help prevent unwanted air from entering the suction path during pump operation.
Pump Inlet Connection
The suction assembly connects the coating supply path to the pump inlet so material can enter the fluid section.
EPX2155 Suction Set Components to Inspect
Inspect the diagram-listed material-intake path for cracks, damage, restrictions, deterioration or other conditions that can interfere with material flow.
Check the applicable strainer for dried coating, debris, physical damage or restriction that can limit material intake.
Inspect fittings and connectors for looseness, damaged threads, cracks or conditions that may allow air into the suction path.
Inspect applicable sealing components for cuts, flattening, deterioration or incorrect seating.
Check the connection between the suction set and pump inlet for looseness, contamination, damage or sealing problems.
Verify that diagram-listed clamps, retainers and related hardware are present, serviceable and correctly positioned.
Diagnose EPX2155 Priming and Material-Intake Problems
When an EPX2155 is difficult to prime, begin at the material supply and work toward the piston pump. This inspection sequence can help separate a suction-side problem from an internal pump problem.
1. Check Material Supply
Confirm adequate coating material and make sure the suction inlet is correctly positioned in the material supply.
2. Inspect the Strainer
Check the applicable inlet strainer for dried material, debris or restriction that can reduce material flow.
3. Check for Air Entry
Inspect suction connections, fittings and sealing components for looseness or damage that may allow unwanted air into the intake path.
4. Inspect the Pump
If the suction path is clear and properly sealed, continue diagnosis at the piston pump and applicable inlet valve components.
Common EPX2155 Suction Set Problems
Suction-side faults can resemble internal pump problems. Inspect the complete intake path and confirm that it is unrestricted and properly sealed before rebuilding the piston pump.
| Symptom | What to Inspect | Repair Direction |
|---|---|---|
| Sprayer Will Not Prime | Material level, strainer, suction path, fittings and pump inlet. | Remove restrictions and correct verified suction leaks before proceeding to internal pump diagnosis. |
| Intermittent Material Flow | Suction tube or hose, intake connections, strainer and material supply. | Check for restrictions, damaged intake components and unwanted air entering the system. |
| Reduced Pump Output | Inlet strainer, suction path, pump inlet connection and piston pump. | Restore unrestricted material intake, then inspect the pump if output remains reduced. |
| Air Appears in Material Flow | Fittings, connectors, seals and suction tube or hose. | Locate and correct the verified suction-side leak or damaged sealing component. |
| Frequent Intake Restriction | Strainer, coating condition and complete material-intake path. | Clean and inspect the applicable intake components and address the source of repeated contamination. |

Do not select a suction tube, hose, strainer, fitting, connector, seal or other intake component based only on appearance. Similar material-intake parts can differ by dimensions, connection style, sealing arrangement and sprayer configuration.
Confirm the EPX2155 model, P/N 0551104 where applicable, correct Suction Set Assembly diagram, numbered callout, component description, exact replacement part number and required quantity before ordering. Do not assume interchangeability with EPX2255, EPX2355, EPX2455, EPX2555 or another EPX-series sprayer unless the applicable parts information confirms compatibility.
Before Buying EPX2155 Suction Set Assembly Parts
Verify the exact sprayer model before selecting material-intake components.
Confirm the suction assembly reference before using its parts breakdown for component selection.
Check the strainer, suction path, fittings, connections and pump inlet before deciding which component requires replacement.
Match the required component to its numbered callout in the correct exploded diagram.
Confirm the exact replacement part number, description and quantity required before ordering.
