Titan 155-055 Minor Pump Service Kit for Fluid Pump Restoration
Titan 155-055 is an OEM minor pump service kit designed for the 155-559 fluid pump assembly on compatible Commander, Admiral, and PowrCoat spray systems. This maintenance kit contains the polyethylene/leather packings and seals required to restore pump performance when the cylinder and displacement rod are still reusable.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan minor pump service kit containing seals and wear components required for a minor pump rebuild on the 155-559 fluid pump assembly. |
| Function | The minor kit includes the upper and lower polyethylene/leather packings needed to restore sealing performance when the cylinder and displacement rod are reusable. It addresses fluid bypass caused by normal wear of sealing components. The polyethylene/leather construction provides durable sealing with good chemical resistance for most coating materials. |
| Industrial Applications | Professional sprayer repair, fluid pump maintenance, packing replacement, and rental fleet equipment servicing. |
| Compatible Titan Assemblies | 155-559 Fluid Pump Assembly used on Commander; Admiral; PowrCoat. |
| OEM Part Number | 155-055 Minor Pump Service Kit. Alternate part number 0155-055. |
| Related Parts Commonly Serviced Together | Loctite 426-051, 155-559 fluid pump assembly, cylinder, displacement rod, 155-505 major kit, 155-051 leather-only kit. |
| Common Problems Solved | Pressure fluctuation or surging during operation, fluid leakage from the pump packing nut, difficulty reaching or maintaining spray pressure, visible material seepage past the packing retainer, and loss of prime. |
| When Replacement Is Recommended | Use the minor kit when the cylinder and displacement rod are reusable. If the cylinder bore is scored or the rod surface is damaged, the major kit (155-505) is required. If only the leather packings are needed, the minor kit 155-051 is also available. |
| Service Guidance | When servicing the pump, thoroughly clean the cylinder bore and piston rod before installing new seals. Lubricate components during assembly and inspect the piston rod for scoring or wear that could compromise the new seals. Use the included Loctite sealant (426-051) on clean threads of the piston seat. |
| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in compatible spray systems. |
| Commercial Benefits | Restores proper pump sealing, prevents fluid bypass, maintains consistent system pressure, ensures reliable spray performance, and extends equipment service life. |
The 155-055 Minor Pump Service Kit is a practical replacement for contractors who need to restore pump performance without replacing the cylinder or displacement rod. As the pump operates, the reciprocating motion of the piston gradually wears the sealing components, allowing fluid to bypass the packing stack rather than being forced out to the hose and spray gun. When these components become worn, the pump loses its ability to build and maintain consistent pressure. Common indicators that a minor pump service is needed include pressure fluctuation during operation, material leaking from the pump section, difficulty achieving spray pressure, or visible material seepage past the packing retainer. If the cylinder and displacement rod are still reusable, this kit provides the packings required for a complete seal restoration.
