Erosion-Resistant Coatings for Pump Wear Rings & Shafts
Learn how HVOF erosion-resistant coatings help extend the service life of critical pump components, reduce wear-related failures, and maintain operational efficiency in demanding oil and gas environments.
The Challenge
Case and impeller wear rings, plungers, and shafts used in oil & gas pumping equipment are constantly exposed to erosive and abrasive media.
Wear on these close-tolerance components can lead to reduced efficiency, internal leakage, increased maintenance requirements, and costly unplanned downtime.
The Solution
Critical pump components manufactured from SST 416 base material are coated with a Jet Kote JK-135 (Stelcar) HVOF overlay to provide superior erosion resistance.
Following the coating process, cylindrical diamond grinding is performed to restore precise dimensional tolerances and ensure optimal component performance.
- Jet Kote JK-135 (Stelcar) overlay applied over SST 416 base components.
- Suitable for wear rings, plungers, shafts, and other close-tolerance rotating parts.
- Post-coating cylindrical diamond grinding ensures dimensional accuracy.
The Result
- Restored erosion resistance on critical pump components.
- Precise dimensional tolerances maintained after coating.
- Extended service intervals for high-value pump internals.
- Reduced maintenance requirements and improved equipment reliability.
