Titan EPX2455 Pump Repair
Buy Genuine Titan EPX2455 Fluid Section Replacement Parts
The Titan EPX2455 Fluid Section Assembly is the pumping section responsible for drawing coating material into the sprayer, generating fluid pressure and delivering material toward the spray system. Its piston rod, cylinder, packings and check valves work together through repeated pumping cycles.
Over time, abrasive coatings, normal wear, inadequate cleaning and damaged sealing surfaces can affect pump performance. Worn packings may allow fluid leakage, while damaged valve balls or seats can interfere with priming and pressure retention.
AllTitanParts lists individual service components for Fluid Section P/N 0552155, allowing technicians and equipment owners to identify specific repair parts without automatically replacing the complete pump lower.

PUMP SEALING KIT
Titan 0551687 Repacking Kit
The Titan 0551687 Repacking Kit is a service kit intended for rebuilding worn fluid-section sealing components. Pump packings help maintain the seal around moving components during pressurization.
Consider a repacking service when the pump develops packing leakage or pressure loss caused by worn seals. Inspect the piston rod and cylinder before installing new packings.
DIAGRAM REF. 4
Titan 0552156 Cylinder
The Titan 0552156 Cylinder forms a key portion of the fluid-section pumping chamber and provides a working surface for the reciprocating piston assembly.
A scratched, scored or excessively worn cylinder may damage new packings and reduce sealing performance. Inspect the internal surface during pump rebuilding.
DIAGRAM REF. 5
Titan 800-355A Lower Packing Assembly
The Titan 800-355A Lower Packing Assembly provides a specified sealing arrangement within the lower pump section.
Worn or damaged packings can contribute to material leakage and reduced pressure retention. Confirm the required packing configuration and installation procedure before servicing.
DIAGRAM REF. 6
Titan 0552157 Cylinder Adapter
The Titan 0552157 Cylinder Adapter connects the pump cylinder to its designated mating components in the fluid section.
Inspect the adapter for damage to its threads, seating surfaces or body during disassembly. Use the exact specified part to preserve proper fit.
DIAGRAM REF. 7
Titan 0507732 Piston Rod
The Titan 0507732 Piston Rod moves within the fluid section as part of the reciprocating pumping mechanism.
Inspect the rod for scoring, pitting, bending or other surface damage. A damaged rod can accelerate packing wear and cause repeated leakage after repacking.
DIAGRAM REF. 21
Titan 0507229 Piston Rod Assembly
The Titan 0507229 Piston Rod Assembly is a listed pump rod subassembly used within the EPX2455 fluid section.
Check the assembly listing and diagram carefully when choosing between an individual piston rod and a rod assembly. Do not assume both product packages contain identical components.
Inlet and Outlet Valve Components
Titan EPX2455 Inlet Ball, Outlet Ball, Valve Seats and Cages
The inlet and outlet check valves help control material flow through the reciprocating pump. Valve balls and seats must seal correctly for the fluid section to prime and maintain pressure.
Titan 0507452 Upper Cage
Diagram ref. 9. A valve cage component that helps maintain the specified internal valve arrangement.
Titan 0507454 Washer
Diagram ref. 10. Replacement hardware used at the designated fluid-section location.
Titan 9841502 Outlet Valve Ball
Diagram ref. 11. A precision check valve ball that helps regulate material flow through the pump outlet.
Titan 0294516 Outlet Valve Seat
Diagram ref. 12. Provides the specified outlet ball sealing surface. Replaces Titan 944-043.
Titan 800-322 Lower Cage
Diagram ref. 14. A lower valve cage component associated with the inlet check valve arrangement.
Titan 51519 Inlet Ball
Diagram ref. 15. A precision inlet check valve ball. Replaces Titan 800-242.
Titan 00310 Inlet Seat
Diagram ref. 16. Provides the designated sealing surface for the inlet check valve ball.
Titan 800-148 Inlet Valve Housing
Diagram ref. 20. The inlet valve housing supports the specified inlet check valve components.
Fluid Section Operation
How the Titan EPX2455 Fluid Section Works
Material Intake
The inlet check valve allows coating material to enter the pump chamber during the appropriate pumping stroke.
Piston Movement
The reciprocating piston rod moves within the cylinder to change the pumping chamber volume.
Pressure Generation
The piston, packings and check valves work together to pressurize coating material.
Fluid Delivery
The outlet valve controls the passage of pressurized material toward the sprayer's delivery system.
OEM Part Number Cross-References
Titan EPX2455 Valve Part Number Replacements
The fluid section category identifies two replacement part-number references:
- Titan 0294516 Outlet Valve Seat replaces Titan 944-043.
- Titan 51519 Inlet Ball replaces Titan 800-242.
These references apply to the named components only. Confirm the replacement part against the EPX2455 fluid section diagram before ordering.

Repair Planning
Rebuild Your EPX2455 Fluid Section with Individual Parts
The separately listed complete Titan 0552155A Fluid Section Assembly is marked discontinued by the manufacturer. For an existing EPX2455 pump lower, rebuilding with available individual components may be an appropriate repair option when the housing and other critical parts remain serviceable.
A targeted rebuild may involve the 0551687 Repacking Kit, replacement valve balls and seats, or a piston rod and cylinder if their working surfaces are worn. The correct repair depends on inspection findings and the manufacturer's service requirements.
Check availability of every required component before disassembling the sprayer. If major structural parts are damaged or unavailable, consult a qualified technician about manufacturer-approved alternatives.
