Part 108-501 is a major service kit for the pump designed to restore performance, sealing integrity, and reliability on compatible PowrLiner airless sprayers. This kit includes critical wear components required for a comprehensive pump service, helping address pressure loss, leakage, and inconsistent output.
| Part Number | 108-501 |
|---|---|
| Part Description | Major Service Kit – Pump |
| Function | Complete pump service / performance restoration |
| Fits | PowrLiner 5000 |
| Condition | New |
The 108-501 Major Service Kit (Pump) is designed to support a full pump rebuild on the PowrLiner 5000 airless sprayer. Major service kits address multiple wear points at once, making them ideal for restoring pressure, sealing, and overall pumping efficiency.
As pump components wear, sprayers may lose pressure, leak material, or deliver uneven output. Installing a major service kit replaces critical internal wear parts in one service operation, helping extend pump life and reduce unplanned downtime.
| Seal restoration | Replaces worn packings and seals to restore pressure integrity |
|---|---|
| Wear correction | Addresses multiple internal wear points in a single service |
| Performance recovery | Helps restore consistent output and smooth pump operation |
| Loss of pressure | Sprayer cannot maintain consistent working pressure |
|---|---|
| Material leakage | Paint leaking from the pump or fluid section |
| Pulsing output | Uneven spray pattern caused by internal wear |
| Scheduled rebuild | Preventive service after extended runtime or heavy use |
Part 108-501 is compatible with the following airless paint sprayer. Always confirm pump configuration using the correct parts diagram before installation.
| Sprayer Model | Component |
|---|---|
| PowrLiner 5000 | Major pump service kit |
During major pump service, these components are often inspected or replaced at the same time.
Worn inlet valves can reduce prime and contribute to pressure loss.
Outlet wear can cause pulsing and inconsistent spray output.
Air leaks upstream can undermine the effectiveness of a rebuilt pump.
