Part 441-238 Wear Ring is a sacrificial component designed for Hydra M and Hydra Pro Super series equipment. This ring fits within the pump assembly to provide a replaceable wear surface that protects more expensive components from abrasion and friction. Replacing a worn or grooved wear ring restores proper clearances, extends pump life, and maintains optimal performance.

The 441-238 Wear Ring is a precision-engineered sacrificial component used in Hydra M and Hydra Pro Super series pump assemblies. This ring is installed in areas subject to friction and abrasion, providing a replaceable wear surface that protects more expensive components such as the pump housing, cylinder, or end cap from damage.
Over time, continuous operation and exposure to abrasive materials can cause the wear ring to develop grooves, thinning, or surface damage. A worn wear ring can lead to increased internal clearances, reduced pump efficiency, and accelerated wear of adjacent components. Replacing with this new wear ring restores proper clearances and extends the overall life of the pump assembly.
| Sacrificial protection | Wears instead of more expensive pump components |
|---|---|
| Clearance maintenance | Maintains proper internal pump clearances |
| Friction reduction | Provides a smooth bearing surface for moving parts |
| Component alignment | Helps maintain concentric alignment of pump elements |
| Visible grooves | Deep wear patterns or scoring on the ring surface |
|---|---|
| Thinning | Ring thickness reduced from original specification |
| Cracks / breaks | Visible damage to the ring structure |
| Performance loss | Decreased pump efficiency due to increased clearance |
This wear ring is designed for the following models. Always verify your equipment's parts diagram to ensure correct fit and application.
| Brand / Model | Component |
|---|---|
| Hydra M | Wear ring |
| Hydra Pro Super | Wear ring |
When servicing wear rings, these associated components are often inspected or replaced at the same time.
Inspect for scoring or wear; replace if damaged.
Check for wear or damage in the area contacted by the wear ring.
Replace all seals disturbed during pump disassembly.
