Power Transmission

Gicam technology can use DED laser resurfacing to restore precision rotating components in power transmission systems, such as gear shafts and housings, cylinder rods, and pump impellers and shafts. It targets only the worn areas—bearing surfaces, splines, and bores—while maintaining concentricity and balance tolerances.

Pump Shaft Sleeves and Wear Bushings

Sacrificial parts that protect the shaft at the seal: recharge rather than automatically replace them, especially for non-standard sizes.
These sacrificial parts protect the shaft at the mechanical seal or gland and wear down due to friction, corrosion, or abrasion depending on the pumped fluid, with wear concentrated across the entire surface in contact with the seal. DED allows these worn sleeves to be re-machined to their nominal dimensions, offering a cost-effective alternative to routine replacement—particularly for non-standard sizes where lead times are longer.

This repair method is particularly valuable for pump fleets operating continuously (industrial processes), where rapid replacement and the availability of spare parts are critical to minimizing production downtime. DED also allows for the selection of a filler material that is more resistant than the original, thereby extending service life when handling particularly corrosive or abrasive fluids.
Nominal dimension restored → Surface in contact with the seal was resurfaced, rather than systematically replaced.
Fewer production shutdowns → Increased availability of pump farms in continuous operation.

Key takeaways …

Gicam technology can rebuild pump shaft sleeves and wear sleeves to restore them to their nominal dimensions, offering a cost-effective alternative to routine replacement—particularly for non-standard sizes with long lead times. Selecting a repair material that is more durable than the original improves service life when handling corrosive or abrasive fluids.

FAQ

Why repair a shaft sleeve instead of replacing it?

This is especially true for non-standard sizes, which take longer to source: reloading restores the nominal dimension and minimizes production downtime.

Can the filler material be stronger than the original material?
