Metso horizontal slurry pump repair
A recent project carried out by the team at Hayley 247 Dexis saw the company tackle a critical challenge: repairing a heavy-duty 8-tonne high-lift pump designed for the most challenging abrasive slurry applications.
In the demanding world of quarrying, where equipment reliability is paramount, this wasn’t just a routine maintenance job – it was a comprehensive restoration of a vital piece of industrial machinery.
The Hayley team conducted an exhaustive diagnostic inspection, identifying critical wear points that could potentially compromise the pump’s performance. Then, the rehabilitation strategy was multi-faceted.
The work began with a strategic impeller replacement, utilising high-performance materials to restore optimal hydraulic efficiency. Advanced metal stitch repair techniques were employed to rebuild the pump casing’s structural integrity, addressing areas of critical wear.
Precision was key in manufacturing gland sleeves and reinstating original equipment manufacturer (OEM) tolerances to ensure perfect sealing and operational performance. The vacuum pump received a comprehensive refurbishment, further supporting the system’s overall reliability.
A specialised Belzona 1321 ceramic coating was applied to internal passageways, providing enhanced wear resistance and corrosion protection. The entire system was rebuilt using premium-grade components, including new gland packing, gaskets, bearings and seals.
Rigorous pressure testing validated the repair quality and system integrity, with a final protective painting completing the restoration process.
