Real-world Belzona repairs across the Pacific Northwest
Eastern Washington Potato Plant Impeller Repair
October 2024 • Pasco, WA
A potato processing facility was losing pump performance on their transfer line impellers within weeks of installation. The combination of potato starch, silt, and abrasive particulate in the slurry was aggressively eroding the impeller vanes and shrouds, opening up clearances and reducing flow rates. The plant was cycling through replacement impellers at significant cost, and every swap meant shutting down the processing line.
Roller Grip System
June 2024 • Shelton, WA
Conveyor drive drums, feed rollers, and brake test rollers lose grip over time as surfaces wear smooth, causing belt slippage, material misfeeds, and lost production. Traditional fixes like rubber lagging degrade quickly, weld-on cleats create stress points, and knurling polishes out within months — each requiring the roller to be pulled from service for repair.
PCA Pump Refurbishment
November 2023 • Wallula , WA
A local pulp mill was experiencing repeated failures on their stock transfer pumps. The combination of wood fiber slurry, chemical additives, and high flow velocities was eroding the pump casings and impellers, opening up clearances and dropping output. Each time a pump was pulled for repair, the mill faced days of downtime waiting on machine shop rebuilds and the cost of replacement parts that would erode again within months.
Ferry Bearing Rebuild
March 2023 • Seattle, WA
With drydock time running out, the customer confronted a major obstacle: the interior of a key bearing required rebuilding, but welding was off the table. They needed a precise, non‑welded repair method that could be executed in just a few days—without delaying the vessel’s return to service.
