Titan 0005311 Piston Spring
OEM Titan Pump Component
Titan 0005311 Piston Spring is a genuine OEM spring that provides the return force for the piston in the fluid section of compatible AirCoat, ProFinish, Impact, RentSpray, and SprayTech sprayers. It restores consistent pumping action when the original spring is weak, broken, or corroded.
Compatibility
Replace if the spring shows fatigue, distortion, breakage, or corrosion. A weak spring can cause erratic output or pressure loss even if not visibly broken. Always replace the spring during any fluid section rebuild.

Titan 0005311 Piston Spring for Sprayer Fluid Section Service
Titan 0005311 is an OEM piston spring designed to provide the return force necessary for proper pump operation on compatible AirCoat, ProFinish AS1130, Impact, RentSpray, and SprayTech systems.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan piston spring used in the fluid section to return the piston after each stroke, enabling the pump to draw in material and maintain continuous output. |
| Function | Provides the return force that pushes the piston back after each forward stroke, ensuring the pump can complete its full cycle and maintain consistent hydraulic pressure. |
| Manual-Documented Application | SprayTech ED655. The ED655 owner manual lists 0005311 as the piston spring in the fluid section parts list. |
| Catalog-Listed Applications | Titan AirCoat, ProFinish AS1130, Impact 1140, 1040, 1140I/IA; RentSpray 500, 600; SprayTech ED1150, ED2105. Confirm exact model and serial number. |
| Replacement Indicators | Loss of pressure, erratic output, failure to prime, visible breakage, weak spring not fully returning the piston, and reduced pump efficiency. |
| Related Parts Commonly Serviced Together | Piston, seals, O-rings, packing sets, and pump housing components. Inspect these when replacing the spring. |
| Installation Note | Inspect the spring for fatigue, distortion, or breakage during fluid section rebuilds. Replace if any doubt exists, as a weak spring can cause inconsistent operation even if not visibly broken. |
| Target Users / Markets | Painting contractors, rental fleets, maintenance crews, and repair shops running compatible Titan and SprayTech sprayers. |
| Commercial Benefits | Restores consistent pumping action, reliable pressure, and smooth spray performance while reducing downtime from pump failure. |
The 0005311 Piston Spring is a targeted fluid section component, not a complete piston or pump assembly. Before ordering, confirm the part number in the machine parts diagram. Always replace the spring during any fluid section rebuild to ensure proper pump function.
