Pump impeller and casing rebuilding
Erosion-corrosion and cavitation reshape impeller vanes and casing profiles, pulling the pump off its head curve and cutting efficiency.
What is failing
Erosion-corrosion and cavitation reshape impeller vanes and casing wear rings until the pump falls off its head curve. Efficiency drops, the unit draws more power for less flow, and energy cost climbs every running hour. A re-bladed or replacement impeller is a long-lead spare and a balancing job.
How AAS does it
AAS rebuilds vane geometry and casing wear areas with cold-cure metal composites such as Belzona 1311 and 1111, then applies a smooth low-friction overcoat to restore the hydraulic profile. The crew prepares the eroded surfaces, rebuilds to the design contour, and finishes for flow. No weld heat means no need to rebalance the rotor for distortion.
Typically applied with Belzona 1311, Belzona 1111, matched to the service conditions.
The pump recovers its design flow and efficiency, so it draws less power for the same duty. The unit goes back together without a long-lead impeller or a re-balance for weld heat.
How AAS delivers it
AAS performs Pump impeller and casing rebuilding work for Water & Wastewater, Oil & Gas, and Power Generation operations across Baton Rouge and Louisiana, cold-applied and in place wherever possible, on your turnaround schedule. Crews are factory-trained Belzona applicators, the repair system is matched to the service conditions it will see, and urgent failures are covered by 24-hour on-call response. The result is a permanent, engineered repair that returns the asset to service without the cost or downtime of full replacement.
