Decanter centrifuge rebuilds and upgrades
Restore and improve decanter centrifuge performance for sludge dewatering and thickening
If your decanter centrifuge is showing signs of reduced performance due to wear and tear or changing process conditions, it may be time to consider a rebuild. Refurbishing or upgrading your decanter centrifuge can restore, or even improve, sludge thickening and dewatering performance. With decades of expertise in the industry, Alfa Laval can restore equipment to factory OEM specifications, with factory certified welders and mechanics.
A rebuild can be significantly less expensive than a new machine or full rotating assembly. By avoiding expensive engineering or structural expenditures associated with new equipment, you can significantly save time and money while ensuring that you continue to get the process results you need.
Typical scope of a complete decanter centrifuge rebuild
From the Sharples models dating back 20+ years, to the modern ALDEC G3 Vecflow design, the deep knowledge and technology portfolio at Alfa Laval allows for many older machines to receive modern upgrades that can dramatically improve performance and efficiency.
A typical rebuild includes:
- Bowl repairs
- Conveyor repairs
- Wear components (tiles, strips, inserts, etc.)
- Start-up and optimization (typically quoted as optional)
