Titan RentSpray 400 Fluid Section Parts List
Use these published component references to narrow your search for replacement parts. Diagram item numbers are included where shown on the category page. The list does not establish every item required for a complete fluid section rebuild.
Replacement identification: Some individual product listings reference earlier or replacement Titan part numbers. Confirm any supersession, the applicable equipment revision and the contents supplied with each replacement before purchasing.
How the Titan RentSpray 400 Fluid Section Works
The fluid section operates through repeated pumping cycles. Mechanical motion from the motor and gearbox drives the piston assembly, creating the pressure changes required to move coating material through the pump.
During the intake portion of the pumping cycle, material enters through the inlet flow path. The intake check valve allows flow in the intended direction and helps prevent reverse movement. The condition of the intake valve seat is important for this sealing function.
As the piston continues its pumping cycle, material moves toward the outlet valve. The outlet ball and seat operate together to control fluid movement. Damage or contamination at these sealing surfaces can interfere with pressure development.
The pump packing arrangement provides sealing around designated moving components. Worn packings may allow fluid leakage and affect normal operation. The Titan 0551533 Repacking Kit is associated with this maintenance area.
The bypass valve assembly controls its designated fluid routing function during priming and spraying. The filter assembly supports material filtration, while the pump block provides the relevant structural and connection arrangement for these components.
Because these parts interact, a pressure or priming problem may involve more than one service area. Inspect the relevant components using the manufacturer's diagnostic and repair instructions before selecting replacements.
Titan RentSpray 400 Fluid Section Troubleshooting
Pump symptoms may be associated with worn packings, damaged check valve components, intake restrictions or fluid routing problems. The following examples describe possible inspection areas, not confirmed diagnoses.
Sprayer Will Not Prime
Inspect the material supply, suction connections, intake valve and bypass valve arrangement. A restricted inlet or a valve that does not seal correctly may interfere with priming.
Pump Does Not Build Pressure
Review the inlet and outlet check valves, piston assembly, packings and bypass valve. A damaged valve seat or worn sealing component may contribute to pressure loss.
Fluid Leakage Around the Pump
Inspect the relevant packing and sealing locations after following the pressure relief procedure. The Titan 0551533 Repacking Kit or another specified seal may be required depending on the diagnosed fault.
Irregular Pump Cycling
Inspect the mechanical drive and fluid section for abnormal resistance, worn components or valve sealing problems. Pressure control and suction issues may also affect operation.
Restricted Material Flow
Check the applicable suction path, filter assembly and fluid passages for coating buildup or debris. Follow the specified cleaning instructions and inspect for damaged components.
Prime and Spray Switching Problems
Inspect the bypass valve assembly and its designated sealing components. Confirm whether the problem involves the valve mechanism, associated seals or another fluid control component.
High-pressure safety: Airless spray equipment can cause serious fluid injection injuries. Disconnect electrical power and follow the complete manufacturer-specified pressure relief procedure before servicing the pump, valves, filter or fluid connections. Never use your hands to locate a pressurized leak. Do not loosen fittings while the system is pressurized.
Maintaining the Titan RentSpray 400 Fluid Section Assembly
Appropriate cleaning and inspection help identify conditions that may affect pump operation. Follow the RentSpray 400 operating and service instructions for flushing, packing maintenance, valve inspection and storage procedures.
